We too were concerned about this but as Bill and Mark rightly say it just goes away as an irritant after a short time on board.

Re: Wave slap / banging under the stern
Mohammad Shirloo
Hello Stefan;
After the first season aboard Kokomo about 5 years ago, we started looking for a solution for the “banging” you refer to. After a few iterations of trying different solutions, we came up with our final solution that we affectionately refer to as the “slap slap device”.
It basically consists of two layers of mesh fabric (the same material cargo straps are made of), strengthened by 1 inch mesh straps sewed in both directions every 18 inches. The two layers are then sewed together forming several pockets that we have inserted 2 mm waterproof foam for floatation and sound insulation. This is custom made to fit the entire stern from the trailing edge of the rudder to the back of the transom and all the way to the sides about 12 inches above the water line. It has several long straps for attachment to the lifelines/stanchions.
We simply deploy from the stern and slip it under the stern from the sides. We just attach four of the straps to the lifelines (just at the forward/rudder end) and let the rest happily float and move up and down with the water movement, under the stern. This provides an insulated barrier between the water line and the hull, where the hull rises out of the water at the stern and the sound originates from.
It takes one person about 5 minutes to deploy and retrieve. We simply fold and hang on the life lines, after retrieval, to dry.
This will handle almost all conditions that we typically anchor in, where the boat is facing the wind and waves. It does not do as well when larger waves are coming from the stern, but does help to dampen the sound (this is not a common condition). We also deploy her at marinas/harbors where small wavelets are present. As soon as deployed, it transforms the master cabin from a drum machine, into a quiet place to rest and relax. It is on extremely rare occasions that we have to move to the forward cabin due to sound.
We have now utilized our slap slap device for 5 seasons in the Med. It has been used in all conditions from 2-3 knot currents to 35-40 knot winds. She is almost like new and should last for a few more years. It has made a huge difference for us, as the master cabin was one of the major selling points of the 54 and we could not imagine, not being to utilize it.
Happy Sailing;

Re: Wave slap / banging under the stern
Hi Stefan,
In the past, we have effectively used swimming noodles. Put a rope through about three of them and attach each end of the rope to the furthest aft cleats on the toe-rail (level with the portholes of the aft cabin). Pull the noodles into position under the stern.
No that we have been living on the boat for quite some time, the noise no longer bothers us. At first it was very annoying.
With best regards,
Mark

Andrew, You will not find 24 volts in your Euros. Later model Amels have 24 volts, beginning with the Super Maramu. --

Re: Wave slap / banging under the stern
Stefan, I know that this is hard to believe, but the number one cure is time. Over a period of months, this will become less of a distraction to you and you will become more accustomed to it. There are many things you can do and/or buy, but none really changes the waves or the shape of the hull. The slapping issue is caused by the waves or swell, not the Amel 54, although the Amel 54 will be worse than the SM. The 54 has a wider flatter stern hull...more area to slap. --

Re: Final on the genset exhaust fan wiring
Thanks Eric. Your description reflects that the fuse and capacitor are each in series on the load, with the fuse and capacitor parallel to one another. I assume that wiring the
fuse and capacitor parallel to one another and in series on the load is the same as each being wired in-line and in series to the load. I suspect that either way the fuse and capacitor will do their job. Since I am not an electrician, I would wire them in-line and in series to the load with the fuse between the load source and the capacitor and the capacitor between the fuse and blower. But, my method probably isn't as clean and neat. One day I will go back to school, maybe.😀 --

Re: Wave slap / banging under the stern
I notice it in harbour, not at anchor so much, but if I run the fan all night it helps drown it out.

WE have an SM, so we have the same problem perhaps worse. We use large clothes pegs and attach a blanket overboard across the transom .. its a bit of a faffff but it reduces the wave slap. After the condition, we wash the blanket . Good luck. Jean-Pierre Germain, SY Eleuthera, SM 007, Opua, NZ jp.germain45@gmail.com

Raw water pump on Volvo D3
I have another question for the group.
Two years ago in Trinidad I replaced the bearings and seals on the raw water pump on my Volvo D3 as it was dripping sea water. Not ideal since the 12v alternator is directly below!!! Since then it has not leaked a drop it until now. I noticed a few crystals of salt on a little plastic tray, I keep below the pump, whilst putting the boat to bed for the winter. The rebuild two years ago was some 500 engine hours ago. Is that normal? I am a bit disappointed. I was hoping for double that. What to do? 1. Buy whole new pump at a cost of £525. 2. Buy the rebuild kit that includes a new shaft. £225 3. or just fit a new lip seal that costs very little about £5 Nick S/Y Amelia AML 54-019 Bazimakopolos yard, Greece

Wave slap / banging under the stern
Stefan Schaufert
Hello to all,
today a less technical issue. Do somebody got a (temporarily) solution against the banging (and often really annyoing) waves under the stern/ owners bed of the AMEL 53/ 54/ 55 - when on anchor? Best regards Stefan A54 119 Lady Charlyette - Porto Santo

Re: Bowthruster Gear Oil
Thanks James and everyone else. I am home in the UK for the winter. October was gorgeous in Greece. The sea was warm enough to swim and the air pleasantly warm in the day and almost chilly at night.

Ahh, so it has finally cooled off in Greece. But what a nice October we had this year eh? As you have already suspected I am sure that the difference in the flow of the oil is just the viscosity has increase from the temperature. This is the same reason that changing engine oil with the engine warm, much easier. In the future if you have the same problem, just put some gentle heat on the unit such as a 100 watt clamp light or a small thermostatically controlled heater (in a pinch a hair dryer, but keep an eye on these things, not rated for continuous use) . No need to get anything really hot, just bring the oil up to 100F or so and it will be much thinner and should flow. It might take hours of gentle heating to accomplish this, especially if the 54’s have fibreglass cases on the lower units of the bow thruster which does not conduct heat very well. Hope you also had a good season in Greece this year. James SV Sueno Preveza, Greece Also now high and dry..

Re: Desperate plea for an alternator/charging problem - Amel Euros 41, 1976, MD21a engine
Andrew Eaves <andyeaves@...>
Hi John
Thanks for the offer and advice! Sorry for the delay, yes an auto electrician found it in 20 mins. It was the alternator bulb/lamp. What usually comes on when your alternator is faulty in a car, but I never knew this bulb was in the circuit as it never had worked. Lesson learnt here now. Still one alternator to repair and batteries would benefit from being changed. Also to my knowledge this system is now just 12v, I haven't found any 24v lying around anywhere yet.
Thanks for your help, learning curve here!
Regards

Final on the genset exhaust fan wiring

Hi Bill ,Here is how the genset fan is wired: green yellow in the cable to the fan green yellow Blue in the cable to the blue on on the fan Red from the cable to the fuse. Then one side of the capacitor and the brown wire from to the fan connected together to the other side side of the fuse. Black wire from the fan connected to the other side of the capacitor.

Re: black wire on the genset exhaust fan
Eric, There should be two things spliced in series to the load (brown) wire; fuse and the capacitor. The capacitor is likely closest to the fan (blower). Best, CW Bill Rouse Amel Yacht Owners School - www.AmelYachtOwnersSchool.com 720 Winnie St Galveston Island, TX 77550 +1(832) 380-4970
