Re: [Amel] Refrigeration Cooling

karkauai
 

I like it too, Craig. What do you think about my idea of putting a filter in the line from the tank to the pump? A couple of valves would make it easy to change and with good water in the tank it shouldn't need changing often? Any idea how much water is moved by that pump? Would turn over the tank water pretty frequently, I think. You'd have to put the intake very low (is the tank flat or does it have a shape like the hull?) to keep it from sucking air when underway.

I've started a new thread since that was buried.

The best solution I've seen, Kent, was on Burger and Nancy Zapf's boat Halekai (not an Amel). They very simply just feed fresh water to the refrigeration pump from the tank and have the outlet go back to the tank.

That way you've got a closed loop of fresh water going from and to the fresh water tank. No possibility of sea water in the tank and no need for a complicated keel cooler.

Our Amels with the water tanks in the keel will dissipate the heat nicely and you can even run the refrigeration while the boat is on the hard.

A perfect solution that I'll be swtiching to.

Amel Euros 41 questions to ask

jcluddite <jcluddite@...>
 

Hello,

I am considering a Amel Euros 41. As an older Amel can any group members provide insight onto the boats possible trouble spots? Are there any particular questions I should ask outside of the typical old boat questions(engine, rig, sails, ect)?

Thank you.


Re: [Amel] Maramu holding tank

jjjk12s <jjjk12s@...>
 

Andy,

I put in a holding tank which sounds like the same arrangement as Air Ops but ours is in the aft head.

I removed the fascia covering the storage area and had it resprayed and then reused it, although it would be easy enough to make a new one with the cutouts in different places. I cut segments out of some of the shelves behind the fascia which are thin plywood - not right to the edges where they are laminated or totally removing the shelves, but just enough to make space for the tank. What is left of the shelves is likely just as strong as original and the remnants of the shelves chock the tank in place.

The outlet from the toilet goes up behind the fascia on the left side of the tank to the side at the top of the tank. The outlet from the tank is at the bottom of the tank just above the seacock on the left side. A vent comes out of the top of the tank through a charcoal filter which sits on top of the tank and to a stainless steel vent fitting in the near upright part of the deck molding by the portlight. There are no pump out facilities here so I don't have a pump out but that could also be added.

The only problem is that there is not much room so the tank is not huge. The only valve is the seacock and there are no Y valves. The tank I used was previously mounted on the bulkhead under the sink and was emptied (when the pump worked) by a diaphram pump. As the tank is semi-transparent it is possible to just see the level or easy to see the level by shining a torch but some other means of checking the level could be used. The tank should not be allowed to overfill or the charcoal needs to be replaced. I can't think of a simpler system and nearly all the pipework is behind the fascia which can be removed if necessary to access the tank, vent filter and pipes.

Hi Dave,

Just going through some old posts.

We're having to install a holding tank on our Maramu. The set up you have in your forward head sounds good. Do you have any photos ??

What system did you end up retro fitting for your aft head.

Any information much appreciated.

Thanks

Hi Ross,
Air Ops (Maramu #104) has a holding tank foward which was installed in the boat when we bought her in 2000. It was supplied by Amel and is mounted behind the head storage panel, in the aft upper half. The head pumps up into the tank and then gravity feeds overboard if the single valve at the thru-hull is open. There is a vent/pump out fitting on the deck next to the toe rail. We've had no issues with it.
There was no holding tank in the aft head so we installed a LectraSan which fits nicely but we've never been happy with it and wouldn't get one again. The boat is now in Mexico and we primarily use the forward head but will have to figure out a solution before we return her to the US. The holding tank from Amel would work just as well in the aft head but it's unlikely they still have them. Might be worth asking, though...

Hmmm. Good points, Jean. Was thinking I could put a filter in line and maybe clean up any sediment that stirs up from the tank bottom while under way.

Hi again, Jean,
After reading about the "keel cooler" I have a couple of questions. Are you concerned at all about leakage of the exchanger into your fresh water tank? Are both fridge/freezer units attached to the same exchanger? How much room does the exchanger take up in the tank (ie how much volume do you lose by doing this?) I've not gotten into my tankage system yet...how difficult is it to mount the exchanger in the tank?
Thanks again, this looks like a great idea.

Very nice, Ann-Sofie. Another question...Did raising the standing height in the cockpit require that the boom could not be pulled down as far? Did you have to recut the main sail? If the boom can no longer be brought down to a position perpendicular to the main, does the mainsail furl smoothly?
On Kristy (SM243) I have to ease the main a bit to open or stow the dodger extension that covers the cockpit. I would like to raise the headroom in my cockpit but am not sure there is room below the boom.

I am impressed with the efficiency of the water-cooled and reinsulated fridges. That looks like a modification worth doing.

How do you adjust your autopilot in different conditions to make it more efficient? That's something I never considered.

Hi Kent,
the height under the fixed bimini roof is 1.80m in the front and
1.84m close to the missen based on a laminate that is 20mm thick based on
15mm Divinycell core and GRP layers on each side. We mounted teak core
where we needed to mount things so the screws could get a good grip.
Regarding our mainsail we have done nothing, we have a laminated
material and the design is the based on the standard measurements giving
us no problems in using the furling functionality.
Using the Raymarine Auto Pilot with self learning functionality you
could influence the reaction time and sensitivity of the Autopilot which
results in a dramatically less power consumption. We bought our unit
2007/8 and we know that later units have been improved from this angle.
The first to do is starting to use the Sensitivity factor that you adjust
on the instrument in the cockpit. This combined with sailing on wind
angle instead of using magnetic course is making a difference.

I do agree with you that despite a similar amount of milage under the
SM keel you learn every day and the respect for the late Mr Amel grows
day by day (from a high position from the beginning).

All the best,

Howard, we have a Super wind generator on top of the mizzen and never hear a thing. Paul, what brand do you have?, I wonder if it makes a difference. The superwind has blades that feather in strong winds so that peak revolutions are controlled and we have no concerns even in gales.

Yes we saw you come into Francis Bay

When we mounted the wind generator on the mizzen we used a thick piece of rubber to dampen the vibration. We still can hear the wind generator when it is working in winds above 15 knots. It can be bothersome but it also alerts us to when we are experiencing high winds to check our position.

Thanks again,
As a general rule, under what conditions do you decrease the sensitivity of the autopilot?  Mine is not set up to sail with the wind angle, only by the compass.  Do most of you use the wind angle or the compass when on autopilot?

Hi Kent,
    the height under the fixed bimini roof is 1.80m in the front and    1.84m close to the missen based on a laminate that is 20mm thick    based on 15mm Divinycell core and GRP layers on each side. We    mounted teak core where we needed to mount things so the screws    could get a good grip.
    Regarding our mainsail we have done nothing, we have a laminated    material and the design is the based on the standard measurements    giving us no problems in using the furling functionality.
    Using the Raymarine Auto Pilot with self learning functionality you    could influence the reaction time and sensitivity of the Autopilot    which results in a dramatically less power consumption. We bought    our unit 2007/8 and we know that later units have been improved from    this angle. The first to do is starting to use the Sensitivity    factor that you adjust on the instrument in the cockpit. This    combined with sailing on wind angle instead of using magnetic course    is making a difference.

    I do agree with you that despite a similar amount of milage under    the SM keel you learn every day and the respect for the late Mr Amel    grows day by day (from a high position from the beginning).

On Kristy (SM243) I have to ease the main a bit to open or stow the dodger extension that covers the cockpit.  I would like to raise the headroom in my cockpit but am not sure there is room below the boom.



I am impressed with the efficiency of the water-cooled and reinsulated fridges.  That looks like a modification worth doing.



How do you adjust your autopilot in different conditions to make it more efficient?  That's something I never considered.

Hi
We have changed our bimini to a fixed roof over the cockpit. On that roof we have mounted 24v solar panel 460 W. Our battery bank includes 8 golfcart batteries providing 520 Ah.
We have changed all lamps to LED, we have changed the compressors to fridge/freeze to fresh water cooling and changed the insulation on them aswell. Which was of big importans for the overall consumption profile
During day time (sailing) we are usually power neutral. Meaning we only have to start the diesel generator for washing or making water.
Our plans is to install a wind generator for additional power during night and cloudy days.
We think that it is better to use the diesel for making speed than making power. So for us, yes it is worth it.

Re: [Amel] Maramu holding tank

I can't tell you what Air Ops did for their aft head but we are installing a composting toilet from a company called Natures Head.

Hi Dave,

Just going through some old posts.

We're having to install a holding tank on our Maramu. The set up you have in your forward head sounds good. Do you have any photos ??

What system did you end up retro fitting for your aft head.

Any information much appreciated.

Thanks

Hi Ross,
Air Ops (Maramu #104) has a holding tank foward which was installed in the boat when we bought her in 2000. It was supplied by Amel and is mounted behind the head storage panel, in the aft upper half. The head pumps up into the tank and then gravity feeds overboard if the single valve at the thru-hull is open. There is a vent/pump out fitting on the deck next to the toe rail. We've had no issues with it.
There was no holding tank in the aft head so we installed a LectraSan which fits nicely but we've never been happy with it and wouldn't get one again. The boat is now in Mexico and we primarily use the forward head but will have to figure out a solution before we return her to the US. The holding tank from Amel would work just as well in the aft head but it's unlikely they still have them. Might be worth asking, though...

Re: [Amel] Re Hard bimini top

Ann-Sofie Svanberg <kanalmamman@...>
 

Hi Danny,
we have not done any changes to the standard measurements for the main and do not experience any problems with the furling functionality. We have the following measurements, close to the standard doh house 1.80 m and close to the missen mast 1.84 m. We have seen a French 54 with a molded unit, we have so far used a slightly convex form built with Divinycell base and glassfibre layers for a total dimension of 20mm which work fine and cost much less to produce. We do agree that the fully molded version is much nicer to look at but we will wait changing until there are more SMs that are interested of buying such a solution.

Thanks Ann,

Always good to see a new way of doing things. We have extended the bimini to the back of the cockpit (removable) and put zip removable curtains all round so we get the full protection. However we have not raised the height so we don't get your advatage of being able to stand and see forward. We have seen a number of SM that have raised the bimini very effectively and attractively, yours is the first we have seen with a hard top. It looks good. I have seen a 54 that had a hard extension professionally constructed in Opua at a cost of NZ$20,000. but it was a fully molded unit.

Thanks again

Hi Kent,
the keel cooler solution is absolutely a possible solution, we choosed our solution based on that the water temperature tends to get above 26-27 Degree Celsius which puts a lot of pressure on the cooling part of the compressor and we did not want a keel cooling unit permanently installed in our water tank. However that solution is a quite solution. The sound from our circulation could be heard but is very low dispite its installed under the sofa in the main cabin.
Good luck

On Kristy (SM243) I have to ease the main a bit to open or stow the dodger extension that covers the cockpit. I would like to raise the headroom in my cockpit but am not sure there is room below the boom.
I am impressed with the efficiency of the water-cooled and reinsulated fridges. That looks like a modification worth doing.
How do you adjust your autopilot in different conditions to make it more efficient? That's something I never considered.
I LOVE this forum! Even with 20K+ nm under my keel I still feel like a rank beginner with an enormous amount to learn. Thais again to all for sharing!

Hi Danny
If you check the album Lady Annila, you will find some pictures of our fixed roof over the cockpit.
To protect us from wind, rain and chilly weather we have a zipper going around the whole roof that we connect 10 panels to, with big windows. If we have all of them closed we are very well protected from the weather. We can take all or some of the panels down. It is free of choice.
The roof is constructed so that you can stand up and navigate and beeing able to see over the cockpit.
The inside hasn't got the final finish yet. But we have mounted a LED tape on the sieling that we adjust with a dimmer.

Hi
We have changed our bimini to a fixed roof over the cockpit. On that roof we have mounted 24v solar panel 460 W. Our battery bank includes 8 golfcart batteries providing 520 Ah.
We have changed all lamps to LED, we have changed the compressors to fridge/freeze to fresh water cooling and changed the insulation on them aswell. Which was of big importans for the overall consumption profile
During day time (sailing) we are usually power neutral. Meaning we only have to start the diesel generator for washing or making water.
Our plans is to install a wind generator for additional power during night and cloudy days.
We think that it is better to use the diesel for making speed than making power. So for us, yes it is worth it.

We are intending to do extensive cruising. Staying out of marina's, and primarily living "On the Hook". We have AGM batteries. Filling the battery bank to 80-85% with a genset or hi capacity engine driven alternator is fairly efficient. The last part of the charge up to 100% is not efficient. (Could be many hrs of genset operation at low load to charge up to 100%). For this reasion we will probably install solar panels. AGM's in particular need to be periodically charged to 100% . Also, ask your battery manufacturer what voltage their particular batteries should be charged at. Charging, no matter what the source, at too low a voltage is inefficient, and at too high a voltage is damaging.
Thank You All for the wonderful Amel information. We loved the Joel Potter movie last night.

Hi firends,
I need your opinion concerning power generator (solar panels , wind generator, water generator) on amel supermaramu 2k; as we know she is a power consuming boat but it is worth to spend money for this kind power generator when we have to use generator for water maker, washer machine and more? In case which of these kind of power generators are more suitable for this boat? One story: during ocean passage I had to turn on generator 3h x2/day, a friend of mine with 2 panels and 1 wind generator has to turn on it 2h x2/day....is it worth????

Re: [Amel] Maramu holding tank

Andy Croney
 

Hi Dave,

Just going through some old posts.

We're having to install a holding tank on our Maramu. The set up you have in your forward head sounds good. Do you have any photos ??

What system did you end up retro fitting for your aft head.

Any information much appreciated.

Thanks

Andy

Hi Ross,
Air Ops (Maramu #104) has a holding tank foward which was installed in the boat when we bought her in 2000. It was supplied by Amel and is mounted behind the head storage panel, in the aft upper half. The head pumps up into the tank and then gravity feeds overboard if the single valve at the thru-hull is open. There is a vent/pump out fitting on the deck next to the toe rail. We've had no issues with it.
There was no holding tank in the aft head so we installed a LectraSan which fits nicely but we've never been happy with it and wouldn't get one again. The boat is now in Mexico and we primarily use the forward head but will have to figure out a solution before we return her to the US. The holding tank from Amel would work just as well in the aft head but it's unlikely they still have them. Might be worth asking, though...

Re: [Amel] Re: Power generators

Hi again, Jean,
After reading about the "keel cooler" I have a couple of questions.  Are you concerned at all about leakage of the exchanger into your fresh water tank?  Are both fridge/freezer units attached to the same exchanger?  How much room does the exchanger take up in the tank (ie how much volume do you lose by doing this?)  I've not gotten into my tankage system  yet...how difficult is it to mount the exchanger in the tank?
Thanks again, this looks like a great idea.

Hi Kent
even easier for the fridge, model keel cool and put the exchanger directly into the freshwater tank .... same system, pumps less!!
NO NOISE

Re: Bundaberg Port Marina

Barry <seagasm@...>
 

Bundaberg Port Marina has survived the storm as far as I have heard. Currently, the Burnett river and Bundaberg is flooded, Tradewinds III has survived so far as she did in the 2011 floods. We have been lucky, some have not. I have no knowledge of the other two Amels up on the hard storage. If they are OK, they will survive the floods.as the storm has passed Brisbane on its way south, still on the coast. We had flown to NZ on holiday and cannot return until this flooding has subsided, I am confident TW3 is OK.

Best regards

Hello Giovanni,
 
Bundaberg Port Marina, less than a mile up the Burnett River, is a modern facility with a large yacht hoist.  The other boat yard (near the city, 12 miles up the river) is less upscale with only a sled to haul boats and as my Maramu was too large for them, your SM will also be too large for them.
 
We are hauled out and in storage for the cyclone season,.  We have not had the opportunity to use and evaluate any of the services (i.e. SS fabrication, riggers, etc.).
 
Our insurance contract specified that we had to be south of Lat 25 S during the cyclone season but we were able to negotiate a change to the contract to read Lat 24 S.
