Kent , Pretty sure this is what I bought and it fit perfectly , there is several sizes available , but I think 1/2" X 1/2" is what I ordered. Take a measurement of your hatches to be sure. It comes from 25 ft. to 100 ft. rolls. I had plenty on board, could have given to you in St. Michaels. Say Hi! to Iris .

RigRite says it will be a month or more before they have Goiot Tradition hatch gaskets available. Does anyone have another source? Joel, is there anyone in S Florida who would have them? Has anyone used another gasket material? Does anyone have the dimensions and hardness of the Goiot gaskets? HatchMasters says they've sold a round profile gasket for these hatches, but won't give a size recommendation. Thanks for any help. Kent SM243 Kristy Currently Ft Lauderdale

Re: [Amel Yacht Owners] Re: Generator charging question
Eric, are the timers on the three cabin air conditioners for staggered starting that you referred to part of the later version SM design or something you retrofitted? It’s an awesome idea as three compressors firing up at the same time can draw a lot of current. Thanks!

Re: [Amel Yacht Owners] Re: Shore power cord
Ryan Meador
Hi Jose, Your usage of the chargers makes sense, particularly given that one is dumb-ish. I don't think most of us need two on a day-to-day basis; I might add a second for redundancy and just not use it unless the first fails. My shore power cord is wired the same as yours, and it's how it was when I bought the boat. I'm certain that is the correct way to hook it to the US power system. There should be no special risk of electrolysis from the ground connection; the only reason you read zero volts between ground and neutral is because they're connected together on shore. There is still the normal risk that all boats face of a DC voltage being present on the ground conductor which could complete a circuit with nearby boats. My boat is equipped with a galvanic isolator to protect against this. Thanks, Ryan

Re: Shore power cord
Jose Venegas
Ryan, as Peregrinus, Ipanema has I a semi-dumb (30 amp) and a smart (60amp) charger, which use together when charging batteries with the generator. When the batteries are accepting less than 60 amp I turn off the dumb charger. So far no issues.
The European voltage in 3 phases is 440 between phases and 220 between phase and neutral while in the US is 220 between phases and 110 between phase and neutral. To get 220 shore power in the US I connect the life and neutral of the cable between two phases of the 60 amp outlet and have the ground connected to the ground of the outlet. Clearly here the two lines going to the system have a voltage relative to the ground. I am not sure how much additional electrolysis this may cause but it is the way it was connected when I bought it.

Re: [Amel Yacht Owners] Re: Generator charging question
eric freedman
Looking at the wiring on Kimberlite Amel Super Maramu #376 it appears that you can draw 25 amps from the genset or shore power without any problem. I don’t know where the 16 amp figure comes from.
The genset I believe is 7.5 kw , yet 25 amps is only 5.75 kw The original Amel wire is also rated at 30 amps as is all the wiring coming from the transfer case to the main electrical panel. Kimberlite does not have a circuit breaker in the aft lazarette, just a breaker on the side of the AC panel. Fair Winds Eric Kimberlite Amel Super Maramu #376

Ryan;
The ACs draw about 4-5 A at 230V. So with all three running and the charger and other systems you will exceed the 16A. At the recommendation of Bill Rouse of Ex BeBe and now AmelSchool.com (had to give Bill a plug, he has been of tremendous help to every one here), we installed a power meter which helps greatly in monitoring the current being used on board so we do not exceed the limits of the type of connection that is feeding the panel. In this manner we can turn systems on-off based on what we need to do on board.
I'm not sure about the SM, but there should be another breaker just for the shore power, before it gets to the main breaker at the panel. On our 54 it is in the aft lazarette, which is the closets point to the shore power connection. I would think that it would be prudent to have a breaker right where the shore power comes in, so that the wires from the shore power connection to the main panel are not left unprotected.
We have spent one winter sailing the Greek Isles. It was the coldest winter in 50 years with temperatures typically in the 30s and winds of force 6-9. We managed to heat the entire boat and run all systems on 16A shore power in most occasions by managing the systems that were used simultaneously. The Amels are extremely well designed to function well in most conditions.
We have not made any modifications to the factory installed systems for the past 3 years that we have owned her, and are very happy with the systems as installed by the factory. The suggestion to us from every one when we first joined the group, which we have now come to appreciate, was to not make any modifications until you have used the boat extensively for over a year.

Interesting that so many marinas as so limiting on power. Is it possible to run all three air conditioners on 16A? I've never measured the draw.
My SM has a shore power cord and main breaker sized for 35A (I was under the impression this is true for all SM). I believe the generator runs through that same 35A breaker, so that's the max there as well (it's basically moot since it's a 9kW generator). My shore power cord could use a replacement, so I've been investigating the possibility of upgrading it to handle 50A. It would be handy to have the extra power to run the heat in the winter. My boat came from the factory with extra dedicated heater circuits, which I don't think are standard, so it would be no trouble at all to exceed 35A draw from the panel.

Shore power cord
eric freedman
Ryan, I bought 100 feet of 10 gauge round black rubber coated wire from Home depot about 8 years ago. It is rated at 30 amps. I hooked it up to a 50 amp USA twist-lock plug and use only the red, black and green ground. DO NOT HOOK UP THE WHITE NEUTRAL. It works well with everything on board running including 3 AC units. The AC units are on timers so they all do not start at once. I have never seen over 16 amps when everything is running. It looks exactly like the factory stock wire supplied by Amel. 100 feet is long but on occasion it comes in handy. I am currently working to make a box to connect into the wire near the pedestal plug with a 35 amp circuit breaker in it. This is because the breaker on the 50 amp pedestal is 50 amps.
Fair Winds Eric Kimberlite Amel Super Maramu #376
I pulled the wire all the way from the stern to the transfer case so there are no splices. I have made a number of adapters for the 30 and 50 amp European plugs that just plug into the 50 amp twistlock.

Re: [Amel Yacht Owners] electrolysis on jib furling gearbox? [1 Attachment]
Danny and Yvonne SIMMS
Hi, welcome to the group. The grease dripping out of the bottom of the gearbox is most likely from the forestay although after 20 years if it has not been replenished there would not be much left. Amel grease the forestay inside the foil to eliminate friction. In hot climates this grease softens and comes out the bottom. Messy. I had my forestay off a couple of years ago and regreased mine as we fed it back into the foil using most of two grease cartridges. The furling was noticeably quieter afterwards. I had been contemplating using a needle point grease gun to pump grease in at the top of the foil in situ but took the opportunity while it was down to do the job. As to the corrosion, salt and water in a situation with two plates and access for water between for 20 years.... I suspect that to be the cause. Regards Danny SM 299 Ocean Pearl Mangonui New Zealand

Re: [Amel Yacht Owners] electrolysis on jib furling gearbox?
Ryan Meador
It's been a while since I've studied this, but I don't think this is electrolysis in the typical sense (even though in most cases people misuse that word to mean "galvanic corrosion"). Galvanic isolators and zincs only afford protection to submerged metal where the ocean completes the circuit. Dissimilar metals in direct contact with each other will galvanically corrode on their own, no ocean required. The solution is to make sure they don't touch using some type of isolating grease. I think Tef-Gel is the brand usually recommended for this type of thing. Ryan

Re: Generator charging question
svperegrinus@yahoo.com
Ryan,
We've run both Mastervolt chargers at the same time for years (100A & 30A). No, if the chargers are properly set to charge at the voltages recommended by the battery manufacturer, it is impossible to overcharge the batteries, because each charger senses what the other one is doing. Cheerio,

Mystery Part
Hi All, I had some work done on the bow thruster. When the person finished up and left this was left on the forward berth. I queried a few people but they had no idea. So I put the question to the masses. Thanks for your time. Regards, Chuck s/v Joy SM2K #388

Peter, I have one end of this grouper permanently attached to the bonding at the fuel fill bonding clamp. As soon as I pull into a marina I always drop it over the side. I had to rig a line to the groupers cable so there was not stain on the wire. You would be surprised how quickly the grouper gets dissolve in some marinas.

Peter,
While you are waiting to install a galvanic isolator, consider buying an additional easy to install (i.e. no haul out required) sacrificial anode like this one or similar: https://www.amazon.com/Martyr-CMGROUPERZ-Alloy-Grouper-Hanging/dp/B001TK98LM
It can be connected to the green/yellow bonding wire at a terminal in the Aft locker and then just hung off the back of the boat. It will give you some additional protection of your underwater metal until you get the issue sorted.
