Bill,

I think that you are making a very important point. If the tank were accidentally pressurized to only 10 PSI (City water pressure I believe is usually around 40, so this would actually be easy to do) and we assume that the tank top is roughly 24 square feet in area, the force acting to “blow the lid” would be more than the designed weight of the boat… A warning label at the tank fill might not be a bad idea?? I have noticed on our boat that the tank fill pipe ID is pretty close to the OD of a normal water hose male end so it would not be hard to have it jam in the hole and that could be bad. I was thinking of always using a short section of hose screwed on to the male hose end so that only the smaller hose would be in the fill pipe which would prevent pressurization of the tank. The air vent will not give you much protection once the vent line was also filled with water when the tank is overfilled, especially if the fill rate is rapid. I doubt that the access plate seals would go before the bond between the tank top and the hull. Perhaps there is a built in relief valve somewhere in the system but I have not seen it anywhere on my tanks or in the plumbing so as you point out, careful filling procedures might be the only protection.

Re: [Amel Yacht Owners] Salt water manifold leaking
Bill Kinney <greatketch@...>
Ben,
Be careful… that leak might be evidence of significant weakening of the part. It would not make for a good day if you were offshore and a branch of the manifold broke off. Bill Kinney SM #160, Harmonie On the Hard, Fort Lauderdale, FL “Ships and men rot in port."

Salt water manifold leaking
Recently there were several forum comments on salt water manifolds. Specifically, concerns about failures on older boats. Today mine failed - actually just sprung a leak. As I will be at Amel Caribes in December I will source new manifold there. Has anyone had experience sourcing this item from Amel? Specifically in Martinique? Ben Driver La Bella Vita Sam 347

Thanks Kent.

A very helpful data point! Harmoinie's previous owner used RTV in some places. And there was a still a touch of water in the oil, but nothing scary. On the other hand, the o-ring on the hub was significantly flattened and dried out. I have a day before my new o-rings arrive and I have to decide what to do. I am sure it’s not a critical decision either way, just hoping for input on what people have found to be “best practice”. Bill

Re: [Amel Yacht Owners] My first bow thruster service...
Hey Bill. My BT always leaked a little several months after replacing the seals. My oil always had water in it when I did my maintenance change with every bottom paint job. Since using RTV, Ib had no water come into the boat or in the oil. I'm careful about how I apply it, and even if the seals looked good, I would change them anyway. Kent Kristy SM243

Re: [Amel Yacht Owners] Minor flood
Bill Kinney <greatketch@...>
Another thought on water tanks that people with lots of years on boats will know through their own, or someone else’s, painful experience: When filling a water tank do NOT jam the water hose down the fill pipe and turn it on at a high flow rate.
It is possible for water to go into the tank faster than air can vent. It takes very little over-pressure before access hatches and such blow their seals. They are not designed as pressure vessels! The resulting leak can be either catastrophic, or subtle and hard to find. In the case of boats built without integral tanks, failure of an entire tank seam can occur. Do not try to fill any tank faster than the liquid can go down the fill pipe by gravity. Patience is a virtue!

My first bow thruster service...
greatketch@...
First thruster service and everything is going fine--much better than the "typical" boat project! Thanks to a great design, and great maintenance from the previous owner. But I have a few detailed questions for the experienced Amel folks. First, the lip seal on the retracting shaft. It is a standard Type 35, rubber coated 60x80, single lip seal. EXCEPT: the new seal I received from AMEL, and the old one that was previously installed, have had the lip spring removed. I can see it was removed from the new, unused part because the impression of the spring is still on the inside of the rubber lip. I am working on the assumption that this is by design and for some reason in this application the spring is not desirable. Correct? Second, the use of RTV on all the joints. I am used to o-rings and lip seals being more than good enough by themselves--when installed properly. When covered in RTV, o-rings become essentially single use because cleaning upon disassembly becomes impossible. Once the RTV hardens, it prevents an o-ring from adjusting itself to small movements of the parts. It is also just messy and hard to keep away from places it shouldn't be. On the lip seals, the rubber coating is designed to "stick" to the wall of the chamber it sits in, and coating it in RTV actually makes it less secure. The posted procedure in the forum basically has every possible joint (including several that are not actually sealing surfaces...) being slathered in RTV during assembly. My 20 year old instructions on bow thruster repair from AMEL do not mention this. Have people found this to be an important addition to the sealing of the thruster assembly? Or do some people do it because "it can't hurt"? If it is important, I'll do it. But left to my own devices I'd skip it and let the seals work as they were designed.

Bow Thruster Jack Screw on 54
hodginsbob@...
I need some help with the wiring circuit for the jack screw that drives the bow thruster up and down. I understand that the set up of the thruster on the 54 is very different that all previous models? I can hot wire 24 VDC to the jack screw motor and make it move up and down. The challenge is in the circuit that is supposed to control the motion and the lights and buzzers at the helm. The circuit has 2 limit switches and 4 relays forward, and the switches and lights at the helm. On Gallivant, I am not the original owner, and there appears to of been multiple attempts by semi knowledgable mechanics (one of them me) at fixing it, so at this point I don't know how it was built originally. The wiring diagram supplied in the Amel manual is not detailed. It does not show indicate when a relay is activated if it opens or closes a circuit, and there are no wire colors marked. Has anyone sorted this out and is there a good schematic? Does anyone know the specifics on the relay that I can buy a complete set? How about a source for those tiny fragile limit switches?

Re: [Amel Yacht Owners] Saints anchorage
Patrick McAneny
Ben , We love Les Saintes , probably our favorite place in the Caribbean . The town is safe and an interesting place to hike about , plenty of places to eat. Years ago there was plenty of places to anchor , now they have placed mooring everywhere , can't remember ,but prices weren't bad. You need to arrive by early afternoon on weekends to get a mooring . New Years Eve is a blast ! If you leave the town astern and go around the first point to port you will see boats anchored there , with snorkeling all around there , consult a dive book for locations.
Wish we were there,

Re: [Amel Yacht Owners] Saints anchorage
ianjenkins1946 <ianjudyjenkins@hotmail.com>
Hi Ben and Gayle,
You will enjoy the Saintes. We anchored happily off Bourg, the main settlement ( whose only hazard is a wonderful dress shop shop with Caribbean coloured dresses, so, Ben, hide your credit card from Gayle). We also anchored on the W side of Ilet a Cabrit and Anse a Cointre.
Good walks ashore. Do go up the hill to the N of Bourg to visit Fort Napoleon. When we were there ( 2009) the fort contained three large glass topped tables with models of 18th century men of war. Being then ignorant of my naval history I saw from the first table that the English and French fleets were lined up in opposition; the second showed the English doing rather well; the third showed the French fleet routed or sunk. It was the battle of the Saintes, 1782, the great victory of Lord Rodney ( he of Rodney Bay in St Lucia ) and it secured the West Indies for England for a very long time.
I told the concierge that I thought it very generous of the French to display this battle, which must be a cruel memory for them. His answer
" Francais ? Nous ne sommes pas francais! Nous sommes de Bretagne ! " I then learnt how the Bretons had settled les Saintes, not the French. Three centuries later they were not about to let anyone forget it. As anyone visiting Brittany today will know , they still pride themselves as being Celts and rather separate from the rest of France.
Have fun.
Ian and Judy, Pen Azen ( named after a rock in Brittany which has huge tides. Nearly 40 years ago in our first, 27 ft boat, we misread guiding lights at 0200 and sailed innocently over a rock called Pen Azen. Only the next day did we see from the chart that at low water the rock dries 28 feet! by chance we had sailed over at the top of a spring tide--which rises 35 feet. Pen is a Celtic word menaing Head and Azen is old French for donkey ( think asinine). The rock has a profile of a donkey's head at low water. We were certainly donkeys on that night and we decided to pay homage to Neptune by calling subsequent boats Pen Azen. Our SM is the fifth by that name. So far, Neptune has repaid our respect )

from experience on our Maramu, opening up all ( tank top hatches to Survey the gelcoat coating condition & the earth plate, the only tank which can easily overflow, once all hatches have been securely bolted & seals properly greased & inspected in position, is the aft tank, Under the sink; easy to access even though tricky to inspect (Mirror or camera needed). 4 openings up top to let pipes through (filling, float, foot pump & electric water pump); however all are well above the high level of water. check also for obstructions on all tanks (forward of #2) give free access to water when filling up (2 holes between each compartment, bottom of tanks). the float measures height of water in tank #1 only. then last resort is to check if leak does not come from faulty connection on copper tubing feeding cold & hot water from pressure bottle, as the tubing is fed through from the engine compartment to location Under the fridge & in time tends to break at the elbow (not easy to reach as this is covered in resin to support tubing, and located Under the pumps shelf in the engine compartment). fair winds & dry feet to you christian alby - Maramu #168 'Désirade VIII' in Canet South of France Christian Alby - France home fixe +33 (0)5 34 39 06 02 home Internet +33 (0)9 60 37 22 72 mobile +33 (0)6 42 69 07 80 De : "James Alton lokiyawl2@...

Re: [Amel Yacht Owners] Minor flood
Graham, I've overfilled my tanks (SM, not Maramu) with the same results. Recently I'm finding fresh water in the bilge when the tank gauge is reading only a little over 900 L (1000L Capacity on SM's). I've checked the inspection ports in the aft two tanks and they are sealed as best I can tell. I've still not been able to access the forward tank. So far I haven't found the cause, but wonder if the float on the gauge could be riding lower than it should. Kent Kristy SM 243

Minor flood
Graham Cresswell <grahamjcresswell@...>
We were on a starboard tack setting out on a passage between Martiniique and Barbados when we noticed quite considerable amounts of dirty water sloshing around in the port bilges and behind the stove and later noticed that there was evidence of dirty water on the sole of the forward heads.
We had topped up our water tank beforeo leaving Martinique. It was already quite full when we started- it had been filled to overflowing a few days earlier. We were surprised it was taking such a long time to fill so stopped before it had reached overflow. It would seem likely that this second water fill had somehow misdirected itself but we are mystified as to the explanation. Has anyone had experienced a similar event. Graham Cresswell Maramu #240

Re: [Amel Yacht Owners] Rudder dismantle
Donato Valente
James, yes we did. The crack looks deep and suspicious and in a position very difficult to inspect. Unfortunately we have a very poor connection and can't then post pictures today. We have finished to prepare the work and tomorrow should unload the rudder. Will also check the nylon (or teflon ? ) bushing inside the central support of the rudder (femelot) but guess not expected to be changed (unless made in two parts ?). Thanks again to Christian for his very detailed step-by-step suggestions.

Deep cycle batteries used in UPS and telecommunication applications are rated in reserve capacity, which is the number of minutes the battery will maintain a constant 25A load at 80 degs. F until voltage drops to 1.75 volts per cell. To provide an approximate conversion to amp-hours, multiply reserve capacity by 0.6.

What would you consider to be a reasonable amperage to consider shutting off your charger. Obviously, there is a law of diminishing returns here. A well respected friend, another Amelian, recommended a shutoff when the pack is down 80ah. This would only be a scenario where the gen set is powering the charger. Obviously a full charge would be attempted with shoreside power. Jeff Spirit Amel54 #14
