Re: Maramu pole attachment to the mast broke off
Bill Kinney
Just to be clear, the "threaded inserts" are usually known in the trade as "rivnuts" I keep a selection of them onboard, they are very handy in a lot of situations. There are fancy tools to install them, but they can be installed with a bolt and a nut, it just takes a little longer.
They are available in a range of sizes and materials. For installation in an aluminim mast, I'd stick with the Aluminum versions. They are a lot stronger than just tapping the mast, and they last a lot longer than pop-rivets. Bill Kinney SM160, Harmonie Annapolis, MD, USA

Re: Depth Tranducer offset Santorin
Bill Kinney
Eric,
Can't tell you exactly what it is, but I can tell you what I used to tell my students to do every time they got on a new boat: Drop a weight on a line next to the boat at the dock. Measure the depth of the water, and compare to the actual reading on the instrument. Adjust the offset as needed. Sure to be right. REALLY important on any charter boat, where people frequently get lost in menus on the instruments and push buttons at random... No telling what the settings are.

Re: Maramu pole attachment to the mast broke off
Mike Longcor (SV Trilogy)
Hi Alex, I have a somewhat similar situation on my SM. A small cleat was ripped out of the mast and it pulled out the threaded inserts. I think the holes in the mast are deformed or enlarged just enough that the same size rivnuts/threaded inserts will not fit properly. If I drill the holes larger, then I don't think the next size up bolts will fit through the cleat. I'm still pondering how to go about this. Ideally I'd like to re-use the cleat I already have. Open to any ideas or suggestions. I think new rivnuts/threaded inserts is the way to go but clearly that comes with its own complications. I think you could modify the holes in your mast and the holes on the plate of your pole mount (if necessary) in order to fit new rivnuts and bolts. For me, I'm not sure drilling out the holes of the small cleat is a good option. FYI, a proper rivnut tool is very helpful when installing as opposed to using nut and bolt. The dissimilar metals in close contact may have accelerated the failure of your rivets. Try to insulate or use something like Tef-Gel when you put the new hardware in. Cheers, Mike Longcor SV Trilogy SM23 NZ

Re: Firefly batteries
Bill Kinney
Paul,
Our batteries are connected like this: ![]() (Except with 8 instead of 6). You might want to check the information about the maximum battery back that can be created. I KNOW that they do not recommend connecting more than 4 in SERIES (as you would if you were making a 48Volt bank), but I can think of no reason that the number of parallel batteries would be limited. My manual doesn't suggest any limit. I found the terminals of the Firefly G31 batteries to be slightly taller than the Lifeline batteries they replaced, but our fitting isn't tight, so a bit of expansion in footprint I would not have noticed. Generally, for any battery, it is not a great idea to have them pressed tightly together. They need a bit of air space to lose heat.. Firefly suggests a minimum of 1cm between batteries. I might be labeled a heretic but do you really NEED 12 batteries? We have never been in a situation where we felt we wanted more than the 8 our boat came with. The Firefly batteries are happy with a deeper discharge profile than the FLA batteries the 54 was designed with. Bill Kinney SM160, Harmonie Annapolis, MD, USA

Mickey, I do not know if you have seen it, but there is a very good explanation of what Henri accomplished in a timeline format on Amel's website. It is named "Our Story" and I have a pdf copy here, but the pdf is not as good as the link below to Amel's website: Visit the Amel Story here: https://amel.fr/en/our-story/ This could be the foundation of your presentation.

Re: Maramu pole attachment to the mast broke off
Alex BAIZEAU
Hey Bill, Thanks for the reply. It’s shiny and heavy so I’m positive it’s stainless steel. One other difference with the SM design is that the locking pin is not traversing, the pin is spring loaded in the lock position ( you can see it in the first picture of my original email ). You need to pull it down using the lanyard to unlock the small pole. I’m going to take it to a machine shop here in Portimao and see what they say regarding copying it in Aluminium.

Re: Maramu pole attachment to the mast broke off
Alex, Are you sure it is stainless steel? If it were my Maramu, I would have larger "small-pole mounts to the mainmast" fabricated in a machine shop from Aluminum and consider welding the larger aluminum mounts to the aluminum mast, although I am not sure if that would require a thicker mast or some sort of backing plate. Of course the new aluminum mount could be riveted. The Super Maramu small-pole mounts were made of aluminum and welded to the mainmast. Also, if you decide to have these fabricated, you might want to announce that in this Group, because I am sure that other Maramu owners would consider joining the order. SM "small-pole mounts to the mainmast" (circled in green) are aluminum and welded to the mainmast:

Maramu pole attachment to the mast broke off
Alex BAIZEAU
Hello everyone, We own a Maramu rigged with the system of twin small and long poles. The piece of stainless steel that attach the port small pole to the mast broke off while deploying the large pole. It's was held in place by rivets but they corroded away. The rivet holes have been enlarged (see attached picture) either by corrosion or when trying to drill the rivets out so I can't just re rivet the piece to the mast. I wonder what are my options to reattach this critical piece of equipement.
Here iare the 3 options that I've though of so far:
or
I would appreciate any suggestion
Thank you so much and have a great day

Re: B&G Sonic Speed failure
Stefan Jeukendrup
Hi David, Looks like you found the document: https://amelyachtowners.groups.io/g/main/files/B%20&%20G%20Sonic%20Speed%20Information/SonicSpeedTroubleshooting.pdf The red led not working means that somewhere in the "loop" there
is a problem: (transmitter on Sonic speed board, transmit sensor,
ultrasonic waves through the water, receive sensor, phased lock
loop, Automatic Gain Control amplifier) I guess you measured the internal power supply already, but did you measure AGC, is it between 1.8 and 2.5V?
Most likely causes: * something in the water path between the 2 crystals ( and that includes fouling and loose rubber caps although unlikely since your resistor values are good) * defecitive board, test by swapping with another one. I have several Sonic speed boards if you need one to test. Hope this is helpfull in some way.

Re: Amel 54 v Beneteau 55
I believe the reason they have twin rudders is solely because of the fat stern. On the lean, a centre located rudder would have to be very long to stay in the water. On my last sailboat, when it went over about 25 degrees of lean the rudder would lose effectiveness and she’d round up (sort of guaranteed it would never capsize even when over canvased.). Two rudders at each corner keeps one rudder submerged always so it makes sense (which is the same reason the Amel 50 and Amel 60 have them) even though they nearly double the drag when the boat is upright such as when sailing downwind. The fat stern also makes some sense as you get a longer waterline (which increases hull speed) on the lean and they plane if driven fast enough. These boats are designed to do better at beam reaches than dead downwind so it is not a bad trade off for them.
That said, putting the wheel(s) at the the very end of the stern is much more problematic on a cruising boat. I will admit it is fun and provides good visibility when under sail but as a cruising boat, you aren't at the wheel much on long passages and a protected helm station like on the Amels makes all the difference in the world when conditions deteriorate - as Eric’s stories aptly illustrate! I can’t imagine being out there in those conditions even with a lifeline on and being in a full immersion suit. We doubled up on ever watch because you just couldn’t spend 4 hours back there in boisterous conditions even in Caribbean climates (and you couldn’t reef the sails by yourself anyway). The racing boats don’t have their helm stations exposed like that and are either optimized for single handed sailing or have scads of crew available to do the changes and keep things optimized. I think Matt’s point is that he doesn’t see the point of twin helms at the ends of the stern for cruising boats and I fully agree with him. Looks great, shows well on test sails but it’s definitely not one of those things like the near centre well protected helm station that you just don’t get until you get “out there” in nasty conditions and then you realize the subtle brilliance of Captain Henri. I notice that the Amel 50 hasn’t abandoned that enclosed helm station even with the twin rudders. My cousin loves their Beneteau as they do fully crewed day charters with it and it has a huge cockpit to hold scads of paying customers and give them the thrill of open cockpit sailing in small chunks. It even allows all the customers to pretty much take over the entire cockpit area and the skipper can have their own little corner with good visibility. For that purpose, it’s a way better design than Amel’s system but that’s not the same use case as Amel’s. Like all things on a sailboat, it’s a compromise and you need to understand the pros and cons of both and compare it against how you actually will use your boat to see if it makes sense for you. There were things I loved about that Beneteau - that huge cockpit would be a wonderful place for all of my 6 grandkids on the hook but it was completely suboptimal for my intentions (long term cruising in different optimal locations separated by inhospitable oceans away from marinas with small crews) so isn’t remotely the boat for me no matter how pretty she was at the dock. My cousin absolutely loves the Beneteau as it is perfect for their uses and it never leaves the Caymans even in hurricane season. It the weather is tough, they don’t have customers that want to be out in it anyway. Good boats for both circumstances that would be lousy at doing each other’s missions. I wouldn’t slag the Beneteau for doing well what it was designed for. Neither would I want to cruise on a IMOCA 60. That’s sailing. Brent

i can’t see the advantage of twin wheels. We’ve seen some, that make it impossible to enclose (Moody deck salon series), making foulies mandatory for any helm work.

B&G Sonic Speed failure
David Crisp
Hi All,
The sonic speed on Wilna Grace has not worked for sometime so with the wisdom learned from this group I've been investigating. Adjusting the spacing knob on the processing unit I'm unable to get the red light to come on. I have disconnected the transducer cables and tested them and all seems okay: - 111.4kΩ on one transducer and 111.7kΩ on the other which seems in tolerance and infinite resistance between all cables and the shielding. Any advice on what I should check next? David Crisp SV Wilna Grace Amel 54 #58

Re: Firefly batteries
Hi Paul,
I doubt Amel changed the size of the cavity. I ordered the batteries with a fellow 54 owner with a much earlier hull number and he had he same problem. I do know the problem was in the few centimeters region but that is all it takes to prevent you from installing 13 (12+1) batteries in the cavity. Keep in mind that the cavity is much bigger then the hole you have to put the batteries trough. I’m not sure anymore but that may have been the problem in the end. It was like playing Tetris with very heavy batteries. Cheers, Arno SV Luna, A54-121

Re: Amel 54 v Beneteau 55
Thanks Danny. That confirmed my suspicions. We didn’t have more than 2-3m seas and 20kts of wind so I didn’t see her bend but like the difference between a Honda Honda Civic and a Mercedes, you can just feel it. (No disrespect to Honda Civic owners… I have both so can make the comparison fairly). Everything felt undersized for the size of the boat.
Pat, we only had about 2 hours upwind and I wasn’t hugely impressed by how well it pointed (I thought it would point better as the Genoa tracks are well inboard of the stays unlike the Super Maramu but I guess it’s beamy enough that it negates the difference. Downwind in 20 knots it did better occasionally surfing down the swells but it’s longer waterline helped a bit too. We saw 10 Kts pretty consistently without surfing and a bit faster when surfing although she’s a big boat so doesn’t accelerate quickly either. Nick, we had to motor sail too when the wind was below 10 knots. It’s a horrible place to be on that aft helm when motor sailing downwind as you sit in a fog of diesel exhaust. I’d be changing from side to side to get away from it. We couldn’t turn upwind on a bit of a reach as we were going by Cuba and didn’t want to get too close so had to put up with dead downwind for much of it until we rounded Cuba (headed for Isla Muerta.). Good thing you have two rudders :-) I saw a video somewhere (maybe here) where people were towing a dingy through that area and the orcas left the rudders alone and played with the dingy. Perhaps dragging some fenders or some such might distract them. Good luck!!! Brent

I have been so disappointed in the sailing performance of this boat…she just does not go..she has a clean bottom…my conclusion is that she is grossly overloaded for the design. The excessive wide stern and twin rudders seam to hold the boat back. In my racing days we used to talk about the “prismatic coefficient” the idea being that in light airs when running downwind boats that scored well outperformed. The excessive wide Beneteau would score poorly and a 54 or Supermaramu would score well. Only when there is sufficient wind to get the Beneteau up onto a plane will she take off…but by then one feels too exposed and reefs! I think the designers look at the super fast open 60’s and try to copy them, but then they add the thrusters and aircons and genset and it just does not work… Does anyone know about the Prismatic Coefficient? After Gib we have to run through Orca alley…which is a bit of a worry. Nick S/Y Amelia AML54 -019

I had one experience with a Beneteau Sense ,heading north past St.Vincent. I was very surprised , I came up from behind ,overtook him and in a matter of a couple of hours lost sight of him along with several production cats we passed.He had a full set of sails flying and they were trimmed well. I always look to be certain that the other boat is trimmed well. I would thought that he would have been the faster boat.

I was in Vuda Point Fiji a couple of years ago and a new Bene Oceanis 55 was alongside me. The professional skipper was delivering her. He had just completed an ocean passage to Fiji. He referred to the boat as a "Bendyto" He was so concerned at the degree of hull flex they had experienced that he was going throughout the boat to check for delamination of stringers before he was prepared to continue the delivery.
I agree the Beneteau is a superb charter and inshore vessel, that's what they are designed for. This applies to many of the other charter designed production boats. They are not designed for ocean crossings, particularly not short handed. I know there are many doing ocean passages but in extreme weather and massive seas I believe they would be dangerous. Not least because of the wide open spaces in the cockpit and below. Serious injuries from falling are a big risk. Likewise, the hulls are not constructed to withstand extreme conditions. Two years ago a Bavaria that had circumnavigated was overwhelmed in a storm just out from Cape Brett at the entrance to the Bay of Islands NZ. A wave broke over her, the cabin windows blew out and she sank in about 20 minutes. Through incredible skill of the rescue services all the crew were rescued but sadly the skipper succumbed to hypothermia.
