That sounds great, José, that Atlantic will add stiffeners. And, yes, leg-out pre-tensioning is what I did and what Atlantic's instructions said - a ratchet-strap is needed to pull the legs together to get them into the preinstalled deck mounts, although that's a finicky process and a rubber mallet helps.
Good luck with it,

Re: Solar Panel Arches

Thank you, James, Craig, and Ian for your thoughts.
James, nice to know that the Emek was only twice that of the Atlantic, I thught it was much more.  Also important to know that the wobbliness is an issue for both the Atlantic and the Emek arches that needs to be corrected by extra cables or struts  
James and Craig,
after several e-mails with the engineer of Atlantic discussing the direction of the pre-tension leg-in or leg-out, I concluded that the leg-out pretention should result in a stiffer and stronger structure than the leg-in pre-tension. This is both due to geometrical and structural considerations, too long to include here but that I would be happy to discuss offline.
So, at some extra cost, I have asked Atlantic to add lateral stiffness to the structure by reinforcing to the forward arch in the same way that they do for the aft arch.  That may not still be good enough and I may have to add a strut or cables to the structure.  It is not that I plan to carry my dingy on long passages but that I want to make the structure as strong as possible in case we are exposed to bad conditions.

Re: Earth bonding and watermaker

 

Arno,

Of course I do not know exactly the cause of the corrosion, but it may be saltwater caused corrosion and was not caused by a missing or poor bonding connection. 

I am not an electrical engineer. Let me attempt to give you a Bill Rouse explanation and answer to your question. Be sure to read all of the Electrical Warnings in your Amel 54 User and Owners manual (You may want to ask SAV at Amel, afterall, that is what they are there for):

Bonding Connections on your Amel 54 were designed to electrically connect devices in contact with water to the anodes on the rudder. There is micro voltage in this pathway and the least amount of corrosion between the bonding wire and the device will cause issues similar to no bonding connection. The metal where the yellow/green wire connects should be free of paint and very clean. The same thing for the bare end of the wire.

EARTH Connections on your Amel 54 are designed to protect you from electrical shock. These connections should cause either the Main breaker to open or the device breaker to open when a 220VAC load line connects to the yellow/green EARTH. An example would be your 220VAC dessalator pump motor has a EARTH connection. If possibly saltwater was spilled on the pump creating a connection between the 220VAC load line and EARTH, breakers will open cutting OFF the 220VAC load line to the electric motor. If in this example if the EARTH connection to the motor was broken, the possibility of electric shock will exist when you touch the motor or anything connected to the motor.

EARTH and Bonding are separate systems, but sometimes EARTH meets Bonding on your Amel 54. A good example of this is the original Calpeda A/C pump. It is connected to Bonding at the output pipe. The 220VAC EARTH is connected to the metal case inside the wiring box. And, of course, the metal case is connected to the output pipe, thus EARTH and Bonding are connected. I believe that the same thing is true on your Dessalator Duo.

I hope this explanation helps. 

Best,

Bill Rouse

Hi All,

I'm wondering about a thing after removing my Duo watermaker. I noticed quite some galvanic corrosion despite the fact that the green/yellow bonding wire was attached at several points to the watermaker.
I was actually just in time taking the thing apart as I'm still able to salvage all the important bits.
From traces I could see I'm guessing one of the endcaps on the pump has been leaking also given the amount of salt build-up at the chassis and pump-base.

What I'm wondering about is the bonding sytem. Is it also connected to the shore power earth lead? From earlier conversations I vaguely remember it was not connected.  If not then why is the earth connection of the 230 Volt pump connected to the mains earth?

Any advise appreciated.

[Edited Message Follows]

Pat,
Here's a link to the US Coast Guard's Simplified Measurement Guide I mentioned.USCG Simplified Tonnage Guide
You can use this for vessels under 79 feet. As Olivier points out different countries have different methods.

You should work it out yourself, but, for your SM it would be ABOUT the following (I had to guess at a couple of numbers but you can fine tune it.
GRT = (Hull volume + Deckhouse Volume) / 100
Where Hull Volume = S x K x L x B x D and Deck Structure Volume = Ls x Ds x Bs 
L, B and D are overall length, breadth and depth, but depth is measured from the deck edge to the bottom of the keel.
You consider the Deck Volume to be 0 if it is less than the hull volume, which it is.
S is a Shape factor which is 0.5 for sailboats. K is a Keel factor which is 0.75 for our shape of sailboat.

So, let's use Richard Colebatch's posting for your SM dimensions. That is 52.49' in Length and  15.09' in Breath.
Richard shows a Water Draft of 6.73' from the bottom of the keel to the water line and let me guess another 6' of freeboard to the edge of the deck.
That would be a Depth of 11.73' (which seems about right as my Santorin's Depth is 10.5')

So the SM Gross Register Tons (GRT) would be (they say to round feet to the nearest tenth):
  S  x  K    x  L     x   B    x  D   
0.5 x 0.75 x 52.5 x 15.1 x 11.8  = 3507  / 100  = 35 GRT
Then, NRT = M x GRT, where M is a Machinery factor which is .9 for sailboats, so
NRT = .9 x 35 = 31  (you are instructed to truncate any fraction)

So, it does seem your numbers are, indeed, way high and should be more like a GRT of 35 and NRT of 31.

Bill Rouse's GRT 27, NRT 24 comes from his Documentation Certificate, I'm sure, but seems low as my Santorin is 31 and 28 and the USCG calculation above is pretty straightforward. Anyway, there are lot of other numbers in this thread that may have their origin in countries other than the US and/or may be weight based. Numbers that have fractions are definitely not US GRT/NRT, which are always whole numbers. Also, in the US the documentation is pretty much self reported with, seemingly, very little checking by the NVDOC. Whatever, your's seems high.

The US Coast Guard's National Vessel Documentation center has a super new website that it very easy to navigate and you may be able to change your numbers on-line. Check it out.

Re: Sharki shaft alternator

Thank you Gerhard this is very interesting and useful information. I am compiling an inventory of my Sharki, do you think it is something all Sharki owners would contribute to and use? It could be invaluable for maintenance, replacing equipment and best practise tips. Do owners already have them? 
Incidentally Sea Hobo will welcome visitors from the EU and the rest of the world while we sort out our appalling attitudes on our forlorn little island.

Coming back to your picture of the gearbox.
I have been searching now for my gearbox sticker but it was difficult to read because this sticker was at baboard side of the gearbox.
As far as I can see the manufacturer is "Hurth" and the type should be "HBW-20-3R". Type HBW-20 is for sure but the ratio (3R) is guessed only because so hard to read.
However it is the same gearbox you have. The oil type is ATF-A and the oil quantity should be 0.3 liters. On top of the gearbox is no ID plate but only the ATF-A sticker.

Earth bonding and watermaker

Hi All,

I'm wondering about a thing after removing my Duo watermaker. I noticed quite some galvanic corrosion despite the fact that the green/yellow bonding wire was attached at several points to the watermaker.

Hi Paul,
This may apply although it involves the distribution manifold and might be of general interest.  When I was in the Amel shop in Le Marin (not that far from you), this caught my eye.  François, who had fabricated it explained that it was for an Amel 54 and I believe he said it was €800.  Looked like a really great idea to me....I took a pic and made a mental note to think about making up one back in the States using Bill's dimensions.  (For you SM owners) he did indicate to me that he would consider fabricating one for an SM.  Gotta love the individual ball valves. Plus acid cleaner possibilities....

Re: Gross tonnage on SM

Beaute Olivier
 

Hello,

a vessel's tonnage is indeed a volume (how much can this vessel carry). This international value is now expressed without unit's name. 
It was previously expressed in tons or tonneaux (for France). This "ton" is not equivalent to a metric ton which is the weight of 1000 liters of water, but it is equivalent to 100 cubic feet which is around 2.837 cubic meter 

Every country's authority has its own calculation for tonnage (from length, beam and inside height).
This is why the tonnage of a Super Maramu is 30.14 in France and is, for instance 33.24 (gross tonnage) and 23.35 (Register tonnage) in UK.
It will for sure be different for Australian or NZ or US flag.

However, Pat's tonnage seems high.

Olivier.
