Re: [Amel Yacht Owners] Re: Mast prebend Amel 54

Beaute Olivier
 

Hello Nick and Alan,

originally, all the AMEL SA, SM and 54 had a slight prebend.
This means that in the harbor, the main mast is slightly curved aft (mast head above mast foot, but a little "belly" at half height. This was done in order that, under sails, especially with a full genoa, close hauling, the mast head would not go forward.
So, with that little curve without sails, the mast should be straight when sailing.
This was absolutely not done for performance.
A slight curve is OK. A big curve will for sure involve mainsail furling issues.

Before changing anything, look at your mast in the harbor, and while sailing, close hauling with the full genoa and mainsail, with 18/20 knots apparent wind. If you see the mast bending forward, you need more tension on the backstay, which may get the mast to bend a little backwards.

All the AMEL 54 main masts that have now been reinforced should have this "slight curve".

I'm sorry but this will not bring much performance...for this kind of sails.

Olivier.

Prebending a mast which has an inmast furling system is asking for trouble.
The furling foil needs to be vertical and the boom horizontal for the sail to furl correctly.

Re: [Amel Yacht Owners] HEADSAIL FURLING

Beaute Olivier
 

Hello Vladimir, and all the SA/SM owners potentially interested in "AMEL" genoa furlers,

AMEL was the designer, but the units and parts were manufactured in Switzerland.
I recently got in touch with the manufacturer of these furlers. The company name is VIKASA ENGINEERING, located in La-Chaux-de Fonds/Switzerland. 
The email contact is: vikasa.vignando@...
The man who knows all about it is Mr. Vignando. The problem is he doesn't speak and write much english.

I asked him a parts list with prices that I hope to get soon.

However, I'm not keen on dealing parts (shipping, etc...) and I have little time for that, so maybe one of you speaking both english and french could help the owners who would like to purchase parts...?

I will revert with the parts list asap.

Olivier.

Mast prebend Amel 54

kwzy6vgkpvtfohjddjsrotobzwf2pjeafjwalhur@...
 

Hello fellow Amelians, 


I notice that nearly all the Amels including the 54, which I have, do not have any prebend in the main mast.

A professional rigger in Antigua, who is very well qualified and rigs huge mega yachts, thinks that the boat would benefit by some prebend. This would be done primarily by tightening the staysail stay and easing the aft lowers. It would he says improve windward performance. I have seen his work on an Amel 54 and I have to admit it looks right. I have spoken with the owner who says it has improved windward performance dramatically. 


So I am keen to try this but I do have some reservations. I am concerned that any prebend that I introduce may cause trouble with the in mast furling possibly jamming. I know for example that if the mainsail clew is lashed too low to the outhaul car then the sail is prone to jamming. I have tried this and if it is as little as 5cm lower than the tack the sail jams. So I fear that by introducing mast prebend I might have problems.


On the other hand a modest amount of prebend might indeed be fine and improve performance. 


Does anyone have any experience with this issue?

Re: [Amel Yacht Owners] Re: Isolated alternators

Thomas,

I can not tell you what was "typically" fitted on an SM because our alternator in not original.

You are correct about the function of the ground relay on the engine, hence the requirement for all the sensors to be two wire style instead of grounding to the engine block.

You are also correct, the Amel floating ground is unusual on FRP boats, but not at all unique. It has nothing to do with having both 12 and 24 volt systems onboard.  Floating grounds are standard on metal hulled boats, especially aluminum hulls, for example. 

Even very knowledgable people will have passionate arguments about the pros and cons of a floating ground. It should be obvious to anyone that either system can work well.  My old boat had it's negative and bond connected together. It had no significant issues and it was 40 years old.  

Some types of corrosion are eliminated by one system, and some types by the other.  Some types of maintenance issues show up on one, and not the other.

The KEY is to be sure that you understand which system you have, and make sure you understand what is needed to keep it as it was designed.  Mixing and matching have to potential to set up stray currents that cause serious problems.

Thanks Bill, 

The original alternator and the replacement are both of the same type: case grounded. I’ll work towards isolating the alternator ext rnal case from the engine block. 

As an owner of an SM, could you indicate what type is typically fitted there?

As an aside, am I right in thinking the solenoid on the negative circuit connects the engine block to the negative terminal of the starter battery only during the start procedure and not all the time the engine is running?

Also, I’d like to understand the advantage of the floating negative in the amel design. It seems to go against the litterature I know of, that tends to indicate the bonding should be connected to the negative battery terminal (if I’m not mistaken). Is it to do with the presence of both 12V and 24V circuits?

Re: [Amel Yacht Owners] Re: Hookah System

Exactly, Craig.  I got the compressor on recommendation of a diver who was cleaning a boat bottom near me a couple years ago.  The CFM rating is 1 at 40psi, which is the pressure at 60ft depth.  Seems to be plenty at 7 ft depths, not sure if I needed to go 20 ft down to unfoul an anchor.

I did NOT add the filter.  It is an oil-less compressor that sits in the cockpit while in use, and the hose is not rubber, it's a PVC hose that the diver said is safe for breathing air.  i purchased a diving hose, but finding coupling adapters has proven difficult.

The only thing you didn't mention that David included is an air filter/water separator in the regulator supply line - trust you did put it in. 

BTW, what is the CFM rating of your compressor and how many gallons is the tank?

Thomas,


There are two significantly different types of alternators, depending on where the how the return circuit to the battery negative is made.
Tter
In a "case grounded" alternator there is usually an attachment on the alternator for the battery Positive wire ONLY.  The connection back to the battery Negative is through the alternator external case, and then through the engine block.  This will not work on an Amel because the engine block is not continuously connected to the battery negative. These are the common alternators used on automobiles.  

Occasionally, this type of "case grounded" alternator has a connection for a battery negative cable on it.  The way to check if your alternator is "case grounded" is to look for continuity between the Negative terminal on the alternator and the the alternator's external case. If the alternator is "case grounded" it will show near zero ohms on this path.  It is not suitable for an Amel UNLESS the case is electrically isolated from the engine block with the plastic inserts.  Putting one of these on an Amel without the isolation parts will make a continuous direct connection between the bonding system (connected to the engine) and the battery negative (connected to the alternator case).  This eliminates the "floating negative" that the Amel was designed with.  It would put all the underwater parts of the boat at risk for stray current corrosion.

The other type of alternator with an "isolated ground" has connections for both battery Positive and battery Negative on the alternator.  This is the best type of alternator, and hopefully the one you have.  On this type of alternator, if you test the resistance between the Negative terminal and the case you will see an open circuit--no connection.  If you have this type of alternator, it can be installed safely without the plastic isolation parts since it is already electrically isolated from its mount to the engine.
