Re: Mainsail furler gasket.

Mark McGovern
 

It can be a complete disaster causing the tapered roller bearing inside the furler to rust and fail completely.  This can cause the furler to seize and make it impossible to unfurl the main sail or worse, make it impossible to furl it in.  To see if yours is damaged, drop it down to manual mode.  It should be relatively easy to turn.  If it is not, you need to tear down and rebuild the furler like I had to do.

See this post I made:  https://amelyachtowners.groups.io/g/main/message/47988

And here is the entire thread on the topic:  https://amelyachtowners.groups.io/g/main/topic/29770769#47988

Mainsail furler gasket.

Gregory Dmitriev
 

Hi guys,
Does somebody know how important can be the damage of this gasket?


Mainsheet traveller Broken on SM#72

Stephen Davis
 

We just broke the attachment point on our mainsheet traveller during our passage from Seattle to San Francisco. We  have SM #72 with the original style track and traveller. Amel changed to a different style system shortly after our boat was built, and changed again with the SM2000. I cannot find any markings on the traveller indicating who’s product it is, and also who would of made the track. I guess the choices would be Goiot, Lewmar, or Antal. Do any of you experts out there know who made these early systems? I bet Olivier, Bill R, or Joel would know. 

We are on our way south, and need to get this sorted out quickly. I suspect due to the age of everything, I may need to replace the track with something more modern. Have any of you ever removed your track from one of the older hulls like mine? How difficult was it to get the screws out. My understanding is the screws are tapped into a steel plate inside the deck. Is this assumption correct? I’m guessing with stainless screws through an aluminum track into a steel plate, I’m likely to shear most of the screws off trying to get them out. 

Any advice on how to repair or replace my traveller system would be greatly appreciated. I’m trying to get the help of a rigger, but all the ones I’m finding seem to be busy for months, and I may be on my own with this. I’ll attach a few pictures of the broken traveller, and what it looked like prior to failure. The attached blocks with soft shackles are something I added recently when the sheaves on the stainless attachment piece fell apart.

Great work, Bill.  Much appreciated.   I am most impressed with the quality of construction of the Incidences Sails and I‘ve bought a lot of sails over the years from all the major makers like North, Doyle, Quantum etc.  The Incidences sails are holding up beautifully and I‘ve yet to have so much as a thread opening up!  

One thing I would like to investigate is whether to have my next main and mizzen built with full length vertical battens like was suggested in a recent post on this site.  I see that Elvstrom is building these types of sails for all the Halberg Rassy boats with furling mains.  Bill, have you discussed that option with Incidences by any chance?

It is very important to inspect the end of the cooler nearest the sea chest. This is where debris will accumulate and reduce water flow. According to Bowman the number 1 failure of the Bowman Cooler is the overtightening of the boot hose clamps on each end. The metal is soft enough that a overtightened hose clamp will squeeze the tubes closed.

Here is a short story for many Amel owners. I had a client who had purchased my Amel Book and 24/7 Support. After about 5 years he decided to sell his Amel. When it was being surveyed the surveyor insisted on running the engine at WOT, the Onan, the water maker, and 3 Air Conditioners. The engine overheated. The surveyor's conclusion was that the Amel sea chest and manifolds were inadequate. My client called and was very distressed. I suggested to him that the Bowman oil cooler had debris inside the boot nearest to the sea chest. Nobody agreed with me and thousands were spent. The sea trial was done again under the same circumstances. The engine overheated again. This time the client removed the large clamp on the end of the Boman Cooler nearest the sea chest and found it full of debris. In 5 years he had never done this, although I recommended it and it is in my book. The moral of this story is easy to figure out. The page from my book is below.

Hi Mark;

 

Thank you for sharing your experience. We removed and had all of the heat exchangers professionally cleaned in 2018. However, it is not possible to identify wear. Therefore I’d like to order a couple of the heat exchangers and replace ours and have one as spare. It is hard to read the part number on the cooler, without removing it.

 

Does anyone know if all A54s used the same part number too, or are there different parts for different hull numbers?

Subject: [Special] [AmelYachtOwners] Bowman DC60-XCC Transmission Oil Cooler Failure; ZF Hurth ZF 25; Yanmar 4JH3-HTE #lessons #lessons

 

In the spirit of Pat from Shenanigans "Lessons Learned" post a few week's back I thought I would share what I learned when my Bowman DC60-XCC oil cooler failed while motoring up the coast of Maine a few days ago.  Thankfully, we caught the failure relatively early in large part due to the fact that when cruising in Maine you have to remain hyper-aware at all times because of the lobster pots that are literally all over the place including in marked channels and anchorages. Because of that, both my wife and I were in the cockpit doing nothing but looking out for lobster pots and calling out their positions to whomever was at the helm. There were no podcasts, no music, no book reading, no headphone, just hyper-vigilance with two people, 4 eyes, and 4 ears on watch at all times. 

The first symptom we noticed was what sounded like a slight misfire of the engine.  It sounded like the RPM increased ever so slightly for just a second.  It was just a "blip" and was not large enough to actually even register on the tachometer.  After hearing it a few times, a minute or so apart, I asked my wife if she was hearing it. She said she was. My first thought was a clogged fuel filter despite the fact that my last fuel fill ups were from fairly busy harbors in Annapolis, MD and Onset, Massachusetts and that we had only ~60 hours on the Racor filter.  In addition, the RPMs of the engine seemed to increase not decrease like I would expect from fuel starvation from a clogged fuel filter.  In any case, I switched over to the second Racor but the occasional engine “blip” did not go away. In fact it got more frequent and it actually started to register on the tachometer just barely.  I put my head over the side to take a look at the engine exhaust.  I did not see any white or black smoke coming out of the engine exhaust.  However, I did see an oil slick trailing behind us the likes of which I have never seen before.  My immediate thought was that the engine oil cooler had failed and was leaking engine oil into the raw water system.  We had no choice but to shut the engine down ASAP.  There was only 6-7 knots of wind directly behind us but we also had a bit of favorable current so we just put out the main sail, turned off the engine and called Towboat US.  We are not at all familiar with this area and we did not see any decent anchorages looking at the charts. We were only 2 nm from our destination of Belfast, Maine and the Towboat captain said it would take him about an hour to meet us at the entrance to the harbor.  So we sailed at 1.5-2 knots with just the Main and met the Towboat captain at the entrance to the harbor where he towed us the last mile to our mooring ball where we still sit right now waiting for our replacement oil cooler to arrive from the UK.

 

Once we were safely moored, I went down to the engine room to check the oil in the Yanmar.  It was perfect.  Not a drop appeared to be missing.  After a brief “wtf?” moment, I checked the transmission dipstick.  The fluid level did not even register on the dipstick at all.  However, I could see that there was some ATF left in the transmission case.  That was a bit of a relief but not much.

 

All of this happened on a Saturday and I do not carry a spare oil cooler so I would have to wait until Monday to order a replacement.  First thing Monday morning I started to call all of the USA dealers for Bowman marine products listed on Bowman’s website.  Of those who actually answered the phone, none of them had the DC60-XCC in stock or even just the DC60 (oil cooler with no end caps). One actually told me that he didn't think DC60-XCC was a valid Bowman part number. I said “I’m looking at their catalog online right now.  It is.”

 

I then called Bowman in the UK and asked if they knew anyone in the USA who might have one of these in stock and they hesitated and said the only one who might have one is Tradewinds Power Corporation.  When I had previously called Tradewinds Power Corporation they said "our computer system is down right now" so we will need to call you back.  They never did.  

Luckily, I had also asked Bowman who in the UK would definitely have them in stock and would ship to the USA.  Without hesitation, they told me that Lancing Marine will definitely have it and they ship around the world.  So I called Lancing Marine (https://www.lancingmarine.com/) and had a wonderful experience buying from them.  Not only were their prices the lowest by far that I had seen anywhere online (79 GBP/~109 USD including new couplers) but the ordering experience was fantastic despite it being phone order only.  The person I spoke to also obviously knows these transmissions well.  His name was Mike and I'm pretty sure he is the owner and founder of the company - founded in 1970!  He gave me his opinion on the state of my transmission (he thinks it’s probably fine) and advice on how to test it to see even before the replacement cooler arrives.  On top of all that, despite it being about 3pm their time when I called, the coolers (I ordered a spare) shipped out the same day.  Last, he said that if I do need to get the transmission rebuilt, that he would highly recommend a company in the lower Chesapeake Bay called Transatlantic Diesels. He says that they know these ZF transmissions better than anyone and he has done business with them for years.  It was really just a great overall buying experience that seems to be so rare in these days of anonymous Amazon purchases.

 

The moral of the story is that for ~$109 plus shipping and an hour of my time I should have replaced the transmission oil cooler PROACTIVELY soon after I bought the boat back in July 2017.  Especially given that I did not know the age of this critical part.  Or I should have replaced one of four times that I have replaced the transmission fluid.  At the bare minimum, I should have had a spare oil cooler already on board.  The engine, and I assume the oil cooler, just surpassed the 2000 hour mark.  Researching this site after the fact I found at least two other SM owners who had the same failure at around the 2000 hour mark. Both, I believe, lost their transmissions.  Hopefully, I have not. I will know in a few days time.

 

So in the spirit of the #lessonslearned, don’t be like me.  If you are not sure how old your transmission oil cooler is, replace it.  If it’s approaching 2000 hours, replace it.  At a minimum, get yourself a spare oil cooler.  And if you can’t find it locally, get it from the nice people at Lancing Marine in the UK so that we all have at least one place in the world that keeps these things in stock.

Thanks very much, Mark, for the post!  My oil cooler on the 55 looks like the photo Bill posted.  When I get back to the boat in September, I can take a look to see what make and model it is and report back to the group.  I‘ve cleaned it out twice - once after 2 years from the boat being new, there was a surprising amount of debris in it.  The next time, after 3 years, there was none.  It was all copper inside and I think it‘s likely a smart idea to replace the cooler after 5 years or so.

In the spirit of Pat from Shenanigans "Lessons Learned" post a few week's back I thought I would share what I learned when my Bowman DC60-XCC oil cooler failed while motoring up the coast of Maine a few days ago.  Thankfully, we caught the failure relatively early in large part due to the fact that when cruising in Maine you have to remain hyper-aware at all times because of the lobster pots that are literally all over the place including in marked channels and anchorages. Because of that, both my wife and I were in the cockpit doing nothing but looking out for lobster pots and calling out their positions to whomever was at the helm. There were no podcasts, no music, no book reading, no headphone, just hyper-vigilance with two people, 4 eyes, and 4 ears on watch at all times. 

The first symptom we noticed was what sounded like a slight misfire of the engine.  It sounded like the RPM increased ever so slightly for just a second.  It was just a "blip" and was not large enough to actually even register on the tachometer.  After hearing it a few times, a minute or so apart, I asked my wife if she was hearing it. She said she was. My first thought was a clogged fuel filter despite the fact that my last fuel fill ups were from fairly busy harbors in Annapolis, MD and Onset, Massachusetts and that we had only ~60 hours on the Racor filter.  In addition, the RPMs of the engine seemed to increase not decrease like I would expect from fuel starvation from a clogged fuel filter.  In any case, I switched over to the second Racor but the occasional engine “blip” did not go away. In fact it got more frequent and it actually started to register on the tachometer just barely.  I put my head over the side to take a look at the engine exhaust.  I did not see any white or black smoke coming out of the engine exhaust.  However, I did see an oil slick trailing behind us the likes of which I have never seen before.  My immediate thought was that the engine oil cooler had failed and was leaking engine oil into the raw water system.  We had no choice but to shut the engine down ASAP.  There was only 6-7 knots of wind directly behind us but we also had a bit of favorable current so we just put out the main sail, turned off the engine and called Towboat US.  We are not at all familiar with this area and we did not see any decent anchorages looking at the charts. We were only 2 nm from our destination of Belfast, Maine and the Towboat captain said it would take him about an hour to meet us at the entrance to the harbor.  So we sailed at 1.5-2 knots with just the Main and met the Towboat captain at the entrance to the harbor where he towed us the last mile to our mooring ball where we still sit right now waiting for our replacement oil cooler to arrive from the UK.

 

Once we were safely moored, I went down to the engine room to check the oil in the Yanmar.  It was perfect.  Not a drop appeared to be missing.  After a brief “wtf?” moment, I checked the transmission dipstick.  The fluid level did not even register on the dipstick at all.  However, I could see that there was some ATF left in the transmission case.  That was a bit of a relief but not much.

 

All of this happened on a Saturday and I do not carry a spare oil cooler so I would have to wait until Monday to order a replacement.  First thing Monday morning I started to call all of the USA dealers for Bowman marine products listed on Bowman’s website.  Of those who actually answered the phone, none of them had the DC60-XCC in stock or even just the DC60 (oil cooler with no end caps). One actually told me that he didn't think DC60-XCC was a valid Bowman part number. I said “I’m looking at their catalog online right now.  It is.”

 

I then called Bowman in the UK and asked if they knew anyone in the USA who might have one of these in stock and they hesitated and said the only one who might have one is Tradewinds Power Corporation.  When I had previously called Tradewinds Power Corporation they said "our computer system is down right now" so we will need to call you back.  They never did.  

Luckily, I had also asked Bowman who in the UK would definitely have them in stock and would ship to the USA.  Without hesitation, they told me that Lancing Marine will definitely have it and they ship around the world.  So I called Lancing Marine (https://www.lancingmarine.com/) and had a wonderful experience buying from them.  Not only were their prices the lowest by far that I had seen anywhere online (79 GBP/~109 USD including new couplers) but the ordering experience was fantastic despite it being phone order only.  The person I spoke to also obviously knows these transmissions well.  His name was Mike and I'm pretty sure he is the owner and founder of the company - founded in 1970!  He gave me his opinion on the state of my transmission (he thinks it’s probably fine) and advice on how to test it to see even before the replacement cooler arrives.  On top of all that, despite it being about 3pm their time when I called, the coolers (I ordered a spare) shipped out the same day.  Last, he said that if I do need to get the transmission rebuilt, that he would highly recommend a company in the lower Chesapeake Bay called Transatlantic Diesels. He says that they know these ZF transmissions better than anyone and he has done business with them for years.  It was really just a great overall buying experience that seems to be so rare in these days of anonymous Amazon purchases.

 

The moral of the story is that for ~$109 plus shipping and an hour of my time I should have replaced the transmission oil cooler PROACTIVELY soon after I bought the boat back in July 2017.  Especially given that I did not know the age of this critical part.  Or I should have replaced one of four times that I have replaced the transmission fluid.  At the bare minimum, I should have had a spare oil cooler already on board.  The engine, and I assume the oil cooler, just surpassed the 2000 hour mark.  Researching this site after the fact I found at least two other SM owners who had the same failure at around the 2000 hour mark. Both, I believe, lost their transmissions.  Hopefully, I have not. I will know in a few days time.

 

So in the spirit of the #lessonslearned, don’t be like me.  If you are not sure how old your transmission oil cooler is, replace it.  If it’s approaching 2000 hours, replace it.  At a minimum, get yourself a spare oil cooler.  And if you can’t find it locally, get it from the nice people at Lancing Marine in the UK so that we all have at least one place in the world that keeps these things in stock.

Looks a bit different than that. Says “C9” on it.

There is a different oil cooler that Amel used in the A55 (possibly all hull numbers). I am not sure of the brand, but the same thing applies to the end closest to the sea chest. Here is a photo of the oil cooler on the A55.

Scott, same Bowman cooler on Yanmar SMs and 54 D3s.
It is very important to inspect the end of the cooler nearest the sea chest. This is where debris will accumulate and reduce water flow. According to Bowman the number 1 failure of the Bowman Cooler is the overtightening of the boot hose clamps on each end. The metal is soft enough that a overtightened hose clamp will squeeze the tubes closed.

Here is a short story for many Amel owners. I had a client who had purchased my Amel Book and 24/7 Support. After about 5 years he decided to sell his Amel. When it was being surveyed the surveyor insisted on running the engine at WOT, the Onan, the water maker, and 3 Air Conditioners. The engine overheated. The surveyor's conclusion was that the Amel sea chest and manifolds were inadequate. My client called and was very distressed. I suggested to him that the Bowman oil cooler had debris inside the boot nearest to the sea chest. Nobody agreed with me and thousands were spent. The sea trial was done again under the same circumstances. The engine overheated again. This time the client removed the large clamp on the end of the Boman Cooler nearest the sea chest and found it full of debris. In 5 years he had never done this, although I recommended it and it is in my book. The moral of this story is easy to figure out. The page from my book is below.

Hi Mark;

 

Thank you for sharing your experience. We removed and had all of the heat exchangers professionally cleaned in 2018. However, it is not possible to identify wear. Therefore I’d like to order a couple of the heat exchangers and replace ours and have one as spare. It is hard to read the part number on the cooler, without removing it.

 

Does anyone know if all A54s used the same part number too, or are there different parts for different hull numbers?

 

Respectfully;

In the spirit of Pat from Shenanigans "Lessons Learned" post a few week's back I thought I would share what I learned when my Bowman DC60-XCC oil cooler failed while motoring up the coast of Maine a few days ago.  Thankfully, we caught the failure relatively early in large part due to the fact that when cruising in Maine you have to remain hyper-aware at all times because of the lobster pots that are literally all over the place including in marked channels and anchorages. Because of that, both my wife and I were in the cockpit doing nothing but looking out for lobster pots and calling out their positions to whomever was at the helm. There were no podcasts, no music, no book reading, no headphone, just hyper-vigilance with two people, 4 eyes, and 4 ears on watch at all times. 

The first symptom we noticed was what sounded like a slight misfire of the engine.  It sounded like the RPM increased ever so slightly for just a second.  It was just a "blip" and was not large enough to actually even register on the tachometer.  After hearing it a few times, a minute or so apart, I asked my wife if she was hearing it. She said she was. My first thought was a clogged fuel filter despite the fact that my last fuel fill ups were from fairly busy harbors in Annapolis, MD and Onset, Massachusetts and that we had only ~60 hours on the Racor filter.  In addition, the RPMs of the engine seemed to increase not decrease like I would expect from fuel starvation from a clogged fuel filter.  In any case, I switched over to the second Racor but the occasional engine “blip” did not go away. In fact it got more frequent and it actually started to register on the tachometer just barely.  I put my head over the side to take a look at the engine exhaust.  I did not see any white or black smoke coming out of the engine exhaust.  However, I did see an oil slick trailing behind us the likes of which I have never seen before.  My immediate thought was that the engine oil cooler had failed and was leaking engine oil into the raw water system.  We had no choice but to shut the engine down ASAP.  There was only 6-7 knots of wind directly behind us but we also had a bit of favorable current so we just put out the main sail, turned off the engine and called Towboat US.  We are not at all familiar with this area and we did not see any decent anchorages looking at the charts. We were only 2 nm from our destination of Belfast, Maine and the Towboat captain said it would take him about an hour to meet us at the entrance to the harbor.  So we sailed at 1.5-2 knots with just the Main and met the Towboat captain at the entrance to the harbor where he towed us the last mile to our mooring ball where we still sit right now waiting for our replacement oil cooler to arrive from the UK.

 

Once we were safely moored, I went down to the engine room to check the oil in the Yanmar.  It was perfect.  Not a drop appeared to be missing.  After a brief “wtf?” moment, I checked the transmission dipstick.  The fluid level did not even register on the dipstick at all.  However, I could see that there was some ATF left in the transmission case.  That was a bit of a relief but not much.

 

All of this happened on a Saturday and I do not carry a spare oil cooler so I would have to wait until Monday to order a replacement.  First thing Monday morning I started to call all of the USA dealers for Bowman marine products listed on Bowman’s website.  Of those who actually answered the phone, none of them had the DC60-XCC in stock or even just the DC60 (oil cooler with no end caps). One actually told me that he didn't think DC60-XCC was a valid Bowman part number. I said “I’m looking at their catalog online right now.  It is.”

 

I then called Bowman in the UK and asked if they knew anyone in the USA who might have one of these in stock and they hesitated and said the only one who might have one is Tradewinds Power Corporation.  When I had previously called Tradewinds Power Corporation they said "our computer system is down right now" so we will need to call you back.  They never did.  

Luckily, I had also asked Bowman who in the UK would definitely have them in stock and would ship to the USA.  Without hesitation, they told me that Lancing Marine will definitely have it and they ship around the world.  So I called Lancing Marine (https://www.lancingmarine.com/) and had a wonderful experience buying from them.  Not only were their prices the lowest by far that I had seen anywhere online (79 GBP/~109 USD including new couplers) but the ordering experience was fantastic despite it being phone order only.  The person I spoke to also obviously knows these transmissions well.  His name was Mike and I'm pretty sure he is the owner and founder of the company - founded in 1970!  He gave me his opinion on the state of my transmission (he thinks it’s probably fine) and advice on how to test it to see even before the replacement cooler arrives.  On top of all that, despite it being about 3pm their time when I called, the coolers (I ordered a spare) shipped out the same day.  Last, he said that if I do need to get the transmission rebuilt, that he would highly recommend a company in the lower Chesapeake Bay called Transatlantic Diesels. He says that they know these ZF transmissions better than anyone and he has done business with them for years.  It was really just a great overall buying experience that seems to be so rare in these days of anonymous Amazon purchases.

 

The moral of the story is that for ~$109 plus shipping and an hour of my time I should have replaced the transmission oil cooler PROACTIVELY soon after I bought the boat back in July 2017.  Especially given that I did not know the age of this critical part.  Or I should have replaced one of four times that I have replaced the transmission fluid.  At the bare minimum, I should have had a spare oil cooler already on board.  The engine, and I assume the oil cooler, just surpassed the 2000 hour mark.  Researching this site after the fact I found at least two other SM owners who had the same failure at around the 2000 hour mark. Both, I believe, lost their transmissions.  Hopefully, I have not. I will know in a few days time.

 

So in the spirit of the #lessonslearned, don’t be like me.  If you are not sure how old your transmission oil cooler is, replace it.  If it’s approaching 2000 hours, replace it.  At a minimum, get yourself a spare oil cooler.  And if you can’t find it locally, get it from the nice people at Lancing Marine in the UK so that we all have at least one place in the world that keeps these things in stock.

Re: Bowman DC60-XCC Transmission Oil Cooler Failure; ZF Hurth ZF 25; Yanmar 4JH3-HTE #lessons

 

For A55 owners and possibly A50 owners (an A50 owner please verify)

There is a different oil cooler that Amel used in the A55 (possibly all hull numbers). I am not sure of the brand, but the same thing applies to the end closest to the sea chest. Here is a photo of the oil cooler on the A55.

It is very important to inspect the end of the cooler nearest the sea chest. This is where debris will accumulate and reduce water flow. According to Bowman the number 1 failure of the Bowman Cooler is the overtightening of the boot hose clamps on each end. The metal is soft enough that a overtightened hose clamp will squeeze the tubes closed.

Here is a short story for many Amel owners. I had a client who had purchased my Amel Book and 24/7 Support. After about 5 years he decided to sell his Amel. When it was being surveyed the surveyor insisted on running the engine at WOT, the Onan, the water maker, and 3 Air Conditioners. The engine overheated. The surveyor's conclusion was that the Amel sea chest and manifolds were inadequate. My client called and was very distressed. I suggested to him that the Bowman oil cooler had debris inside the boot nearest to the sea chest. Nobody agreed with me and thousands were spent. The sea trial was done again under the same circumstances. The engine overheated again. This time the client removed the large clamp on the end of the Boman Cooler nearest the sea chest and found it full of debris. In 5 years he had never done this, although I recommended it and it is in my book. The moral of this story is easy to figure out. The page from my book is below.

Hi Mark;

 

Thank you for sharing your experience. We removed and had all of the heat exchangers professionally cleaned in 2018. However, it is not possible to identify wear. Therefore I’d like to order a couple of the heat exchangers and replace ours and have one as spare. It is hard to read the part number on the cooler, without removing it.

 

Does anyone know if all A54s used the same part number too, or are there different parts for different hull numbers?

Re: Bowman DC60-XCC Transmission Oil Cooler Failure; ZF Hurth ZF 25; Yanmar 4JH3-HTE #lessons

Colin - ex SV Island Pearl
 

Mark, congrats on a great post as the transmission oil cooler is particularly important learning for all new or existing SM and/or 54 owners. We had a similar experience on SM Island Pearl II (2001 build with Yanmar 75HP) when she had only approx 1400 engine hours, but was aged approx.10 years old from new. In our case, we had just completed a gentle 12nm motor sail and on coming into a safe anchorage after dropping anchor we noticed she would not engage reverse (or later fwd either) gear to pull back on the anchor. Fortunately, we noticed it just when it occurred so were able to immediately replace the part, and also immediate do 5-6 oil changes back-to-back, each with new transmission oil to be totally sure that absolutely all moisture was drained out ... and ..... for years later ... that transmission was absolutely perfect for a circumnavigation, and many more motoring years ahead. Remember the cost of oil is cheap compared to the hassel and expense of replacing that transmission.
 
Based on our experience, and what we saw on other Amels during our circumnavigation, I would personally always carry a spare oil cooler and replace this part every 7 years or 2000 hours, and also immediately if ever purchasing a 2nd hand 53 or 54 where the prior owner was not certain (with receipts) about when it was last replaced.

Losing your engine drive power can be extremely dangerous, and here is just one example ... 

In 2018 we were buddy sailing in the Indian Ocean with friends on a beautifully maintained late 2014 SM and, just 9 hours out to sea after leaving the very remote "Bally Bay" on the mid western horn of Madagascar to cross the notorious Mozambique Channel for Mozambique and Richards Bay, South Africa, they hailed us looking for an urgent boat to boat transfer of most of our spare transmission oil supply. After devising a cunning plan we successfully did the ship to ship transfer of oil at sea but the other captain was still sure his oil was just too low as his 100HP Yanmar was in excellent condition (still looked like new!) and so was intent on still proceeding down to South Africa with us despite our urgent suggestion that this could in fact be a failed oil cooler, and for them to rather turn immediately north, and safely down wind, directly for French based Mayotte Island where they could potentially safely sail almost all the way in to a large safe harbour without engine, and where a tow boat could be possible too, plus where that part could be freighted relatively quickly from Amel in France. 

After adding more oil and immediately losing it again, they eventually realised the gravity of their situation took our advice to head for Mayorette where two days later they did infact manage to sail safely in and have the part air freighted in from Amel too. 

As per Murphey's Law when at sea, this decision did indeed become a life-saver as there are absolutely no safe "sail in" anchorages along this section of the Mozambique coast before Maputo, and despite some very fast sailing on the latter third part of this leg, sometimes sitting on 10.5kts SOG pretty much for many hours on end with many peaks over 12kts!, we were still later faced with extreme conditions which our South African weather expert was repetitively calling "extreme life-threatening survival conditions ... divert immediately for Maputo!!..." with a huge unexpected SW gale coming up fast against the very fast moving southerly Augulas currents. In the end we decided to motor sail hard direct for Richards Bay with the last 150nm being extremely heavy going  as the wind against current conditions immediately lifted up what appeared to be huge mountainous waves and really nasty angry seas with winds shreeking through the rigging (I hope we will never see again!) and it was only thanks to having a good reliable motor pushing hard for many hours that we eventually safely got in safely behind the big concrete walls of the Richards Bay harbour just one hour before the real storm conditions really hit creating havoc and destruction along the coastline. We certainly could not have got back to safety without that engine and were so pleased that our friends decided not to press on direct for South Africa.

Moral of the story ... check your oil coolers ... and proactively replace them (they are not that expensive) as you never want to have this fail at the wrong time when you may really need it.

In fact it got more frequent and it actually started to register on the tachometer just barely.  I put my head over the side to take a look at the engine exhaust.  I did not see any white or black smoke coming out of the engine exhaust.  However, I did see an oil slick trailing behind us the likes of which I have never seen before.  My immediate thought was that the engine oil cooler had failed and was leaking engine oil into the raw water system.  We had no choice but to shut the engine down ASAP.  There was only 6-7 knots of wind directly behind us but we also had a bit of favorable current so we just put out the main sail, turned off the engine and called Towboat US.  We are not at all familiar with this area and we did not see any decent anchorages looking at the charts. We were only 2 nm from our destination of Belfast, Maine and the Towboat captain said it would take him about an hour to meet us at the entrance to the harbor.  So we sailed at 1.5-2 knots with just the Main and met the Towboat captain at the entrance to the harbor where he towed us the last mile to our mooring ball where we still sit right now waiting for our replacement oil cooler to arrive from the UK.

 

Once we were safely moored, I went down to the engine room to check the oil in the Yanmar.  It was perfect.  Not a drop appeared to be missing.  After a brief “wtf?” moment, I checked the transmission dipstick.  The fluid level did not even register on the dipstick at all.  However, I could see that there was some ATF left in the transmission case.  That was a bit of a relief but not much.

 

All of this happened on a Saturday and I do not carry a spare oil cooler so I would have to wait until Monday to order a replacement.  First thing Monday morning I started to call all of the USA dealers for Bowman marine products listed on Bowman’s website.  Of those who actually answered the phone, none of them had the DC60-XCC in stock or even just the DC60 (oil cooler with no end caps). One actually told me that he didn't think DC60-XCC was a valid Bowman part number. I said “I’m looking at their catalog online right now.  It is.”

 

I then called Bowman in the UK and asked if they knew anyone in the USA who might have one of these in stock and they hesitated and said the only one who might have one is Tradewinds Power Corporation.  When I had previously called Tradewinds Power Corporation they said "our computer system is down right now" so we will need to call you back.  They never did.  

Luckily, I had also asked Bowman who in the UK would definitely have them in stock and would ship to the USA.  Without hesitation, they told me that Lancing Marine will definitely have it and they ship around the world.  So I called Lancing Marine (https://www.lancingmarine.com/) and had a wonderful experience buying from them.  Not only were their prices the lowest by far that I had seen anywhere online (79 GBP/~109 USD including new couplers) but the ordering experience was fantastic despite it being phone order only.  The person I spoke to also obviously knows these transmissions well.  His name was Mike and I'm pretty sure he is the owner and founder of the company - founded in 1970!  He gave me his opinion on the state of my transmission (he thinks it’s probably fine) and advice on how to test it to see even before the replacement cooler arrives.  On top of all that, despite it being about 3pm their time when I called, the coolers (I ordered a spare) shipped out the same day.  Last, he said that if I do need to get the transmission rebuilt, that he would highly recommend a company in the lower Chesapeake Bay called Transatlantic Diesels. He says that they know these ZF transmissions better than anyone and he has done business with them for years.  It was really just a great overall buying experience that seems to be so rare in these days of anonymous Amazon purchases.

 

The moral of the story is that for ~$109 plus shipping and an hour of my time I should have replaced the transmission oil cooler PROACTIVELY soon after I bought the boat back in July 2017.  Especially given that I did not know the age of this critical part.  Or I should have replaced one of four times that I have replaced the transmission fluid.  At the bare minimum, I should have had a spare oil cooler already on board.  The engine, and I assume the oil cooler, just surpassed the 2000 hour mark.  Researching this site after the fact I found at least two other SM owners who had the same failure at around the 2000 hour mark. Both, I believe, lost their transmissions.  Hopefully, I have not. I will know in a few days time.

 

So in the spirit of the #lessonslearned, don’t be like me.  If you are not sure how old your transmission oil cooler is, replace it.  If it’s approaching 2000 hours, replace it.  At a minimum, get yourself a spare oil cooler.  And if you can’t find it locally, get it from the nice people at Lancing Marine in the UK so that we all have at least one place in the world that keeps these things in stock.

Thanks Bill.
Greatly appreciated. Don’t need sails yet, but it’s a great feeling to have this solution.


Flexible Solar Panels

Matt & Michelle Day, SM#208 SV Talia
 

As Michelle and I are preparing to do our electrical system upgrade (arch, rigid panels, inverter/charger, LiFePO4 batteries), I came across several new CIGS flexible panels.  The white papers on these panels are interesting.  Their advertised wattage is lower, but they are much more tolerant to decreased performance due to high  temperatures.  Therefore, your daily output may actually be higher than traditional flex silica panels.

Does anyone here have any real world experience that can validate/invalidate the lab tests?

Thanks Scott.
The problem with fear is that it has an irrational component and so defies logic.

Paul,

To assuage the Admiral's fears, we've been cruising more or less full time since 2018 and were in Panama when covid hit. Sailed to Hawaii, had a great 6 months and then sailed to French Polynesia, which we love.

We left the boat during the January worldwide surge and I (as an American) had no trouble getting into Europe despite the travel ban.

Sadly there's a surge here now and tomorrow, we are flying from Tahiti to the US and then to Europe. The bigger issue is that many maritime borders are closed. But that's surmountable too as we got into FP via a 2 page exemption form. When there's a will, there's a way. 

Karen - Sorry for thread drift.

All,

 

I have been negotiating with Incidence Sails for some time to get special pricing for Amel owners. As many of you know Incidence is the supplier of sails to Amel. The terms and prices I negotiated for HydraNet sails for most model Amels are the same or less than the terms and prices that I negotiated with QSails. As most of you are aware, I negotiate these prices for my clients. I leverage the size of my client base (currently over 250) for a discount for my clients. There is absolutely nothing for me in this because I never accept payments or commissions of any kind from anyone except my clients. I place advertisements in my Amel Book and on my website for the vendors that offer discounts to my clients, but there is no cost to the vendor. This way I can be a totally unconflicted third party in helping my clients. 

 

I will release the final terms and prices shortly. These prices and terms will apply to all of my clients and any member of the Amel Yacht Owners Group. The negotiated prices are especially good on HydraNet, saving thousands on a complete set of sails. I also negotiated very good prices on lesser quality sails for your Amel from Incidence. Anyone wanting the information right away, email me at brouse@...

 

Nick, 

 

I am sending you the information directly.

I am also thinking of Q sails in Turkey, now that the Greek/Turkish border has opened. Should be VA T free!

Anyone have any good or bad experiences with Q sails?

Good morning Eric, 

I might have some plastic slider left.

I wrote to Maud and asked for the plastic sliders foe the curtains on the windows, hatches , and shower curtains.

Maud mentioned they no longer stock them.

Does anyone have a source for them?

 

When I received my new engine, I was surprised that Yanmar has an option for an oil cooler attached to the engine.

It is so nice. I was always worried about the rubber end caps on the oil cooler on the 4jh3.

You're on a 54, right? Is it the same part number as on a SM?
