I think I can speak for us 54 owners: we are listening closely. 
Can the rest of the discussion be public and include us?  

Many thanks

Hi Bob,
Amel has sent me their work instrucition for doing this, which I have attached. Interestingly they do not say to lower the bow thruster first, and also their procedure looks to be quite a bit more complicated than just removing just a few bolts. So I'm not sure which procedure to use. I'd be interested in your view on this, especially as you have done this before. Is it the same arrangement on the 55?

Re: [Amel Yacht Owners] Re: How much anchor chain?

I have an Amel 54 (Amelia #019 2006) she is my third boat and my largest.  I have concerns that 10mm chain is not strong enough, for such a large vessel. She has very rusty 10mm chain. Unknown grade, but presumably supplied by Amel from new.

Does anyone know what grade 10mm chain Amel supplied 

My last boat was 46 ft and 10T, a Bowman 46. I cruised her extensively and used 10mm Aqua 4 chain. Never felt like it would break.

My previous boat to that was a 35 ft Gaff cutter (Faith of Norfolk) Also 10T that I circumnavigated and used 10mm chain. I am not sure what grade it was. I also felt than the chain was super strong.

The sheer size and windage of Amelia suggests to me that she needs 12mm chain not 10mm.  Not to mention the massive bow rollers and well built bow structure and anchoring system sporting what to my eye looks like puny chain!

However looking at the (aquachain.it) Maggi chain web site I find that if I use Aqua 7 10mm grade chain then I will have a breaking strain that is more than the 12mm  grade 4.

The drawbacks are price and re-galvanising. Apparently re-galvanising grade 7 may weaken it slightly though not by very much.

Any thoughts out there?

As a default, it is a perfectly rational and safe assumption to never use a connecting link. You will never have a failure because of that decision.  But properly sourced and assembled they are safe and useful.

One of the interesting things you learn hanging out in yards around really big boats is that in larger sizes, chain comes in "shots".  One "shot" of chain is 15 fathoms, or 90 feet.  On large yachts and ships, anchor chains are all assembled from "shot" lengths using riveted "c-links" to connect them.

Properly made, drop-forged, heat treated, c-links should be as strong as the chain itself.  The issue is:  how do you know you have a properly made one and not some brittle cast steel POS from an anonymous Chinese steel mill? 

With any "mission critical" shackle or other such metal part, I have always tried to source through an industrial supplier who specializes in such things. That means NOT West Marine, who seems to buy from whoever is cheapest that week.  I have a love/hate relationship with WM.  This is one of those areas I go somewhere else.

Good suppliers who sell parts that are used to lift heavy loads over people's heads tend to be REALLY careful about where their parts come from. They know they are one lawsuit from being out of business. They always have documentation all the way back to the original mill heat that made the steel. And you will pay for that care!

A downside about even the best such connectors is they tend to have very thin galvanizing, and need to be inspected and replaced on a schedule because they rust much faster than the chain they are holding together, especially the rivets that were peened to hold everything together.

Hi Bill

Yes, we had pre-marked that spot on our plotter the night before entering but customs would not have any of that. We were instructed to go to a specific location on the other side and then had to hunt around for 45mins in 50m+ to find a little spot with 42m.

Thanks for the tip about the chain, and yes, Amel are super friendly and helpful. The factory is extremely busy this month with the new 50's, and they have pushed our job in, plus been totally reasonable with the price. Being a management consultant myself, this is the sign of an amazing company, I mean being prepared to drop things and help the 2nd owner of a 16 year old boat!

A lot of corporations could learn a thing or two from this company who's brand is "GOLD" right now. That was not an accident, and yes, of course the guys on Delos have helped quite a bit too.

Best regards to you and Judy.

Colin,

For what it is worth from a SM owner that has been there/done that:

You didn't find the tiny shallow (16 meters) spot at the Male Customs/Immigration lat/lon? There is a little bump in the bottom very close to the lat/lon they publish. However, only 1 or 2 boats can anchor on this tiny spot.

I think 120 of chain is overkill and overweight on your bow. 100 will work, and remember required scope decreases as depth increases. If you still want 120 meters, splice 20 meters of anchor rode to your 100 chain.

I was happy to hear that Amel is making you a new bow thruster. I think all SMs worldwide increased slightly in value with that news.

Thinking all Amel SM's came with 100m chain (instead of 80m) unfortunately stupidly without first measuring it, I cut off 15m chain to leave on our spare anchor (the lovely Stainless CQR that came with this boat from Amel) we now only have 65 m 10mm chain, and getting our 30m rode joined on is a real pain due to the small opening into the chain locker. This has turned out to be the biggest mistake I have yet made with this boat!

Finding anchorages under 20m here in Maldives has been a real challenge. There are no cruising guides yet, just positions from previous cruisers blogs, and two very outdated guides from 1998 and 2005 which have yet to find us an single acceptable anchorage. This has meant pushing the boundaries in crossing un-chartered reef passes almost every single afternoon, to enter lagoons hunting for an anchorage shallow enough. Fortunately we have an aluminium dinghy with a depth sounder fitted, and I send that ahead most afternoons to check depths of reefs before crossing them, but with sufficient chain this would often not be required.

With the balance of the Indian Ocean crossing, South Atlantic, and then the Pacific still in front of us, where there are probably plenty issues finding shallow anchorages, first chance I get we will be moving to new 10mm 120m chain! 

Hope nobody repeats my mistake!

Re: [Amel Yacht Owners] Bowthruster spinning

Bill & Judy Rouse <yahoogroups@...>
 

Dimitris,

This is valuable information about the SidePower Thruster on the 54.

The pin that you mention: 
  • Are you referring to the propeller locking pin (possibly shear-pin)? 
  • There is 1 of these pins for each of the two propellers. I assume that if 1 propellor isn't working it would probably be the pin for that propellor. 
  • Did you experience both of the propellor pins failing at the same time?
  • And, is the pin designed to shear?

Re: Baby on Board and where to go in the Bahamas -

Congratulations!

We live in the Bahamas, on land, with our SM at our sea wall. From 2002 to 2007 we lived aboard our Nordhaven at Grand Bahama Yacht Club, which was closed for awhile but I think it has re-openned.

Since Alex was here, some things have changed. I, personally, would not stay at Port Lucaya— way to noisy and a bit run-down, especially after the last 2 hurricanes, Matthew and Irma. But, across the way, is a small club-like marina with beautiful grounds run by a delightful couple, Barb and Laurie (Laurence) Sykes.

Also, another choice, Ocean Reef has more of a community feel with many boaters returning annually. Also has a pool.

Internet on island is dicey, at best. Rather than depend on any marina, I would suggest getting a sim card from Aliv and getting their unlimited data and cell for about $120/ o or just the unltd data.

Feel free to contact me.

Re: [Amel Yacht Owners] Batteries

Bill & Judy Rouse <yahoogroups@...>
 

Paul,

I respectfully make the following points:
  • My recommendation is to always buy simple lead acid batteries like the DEKA brand DC31DT made by East Penn Manufacturing in the US. Or buy something similar in other parts of the world.
  • These Vmax batteries are AGM...are all of your charging devices capable of AGM charging curves?
  • The Vmax website has no indication of where the batteries are made, or who they are. I suspect a China re-brand, but don't know.
  • Since there are so many distortions of the truth among battery suppliers, how can you trust this? 
  • BTW, I really like how they designed the connections on the battery...I have seen this 8mm bolt connector from other Chinese battery manufacturers.
  • When I Googled the Vmax address I find a small commercial building, apparently not a manufacturer...so I believe that Vmax is a distributor of of re-branded batteries made somewhere, probably China.

Re: How much anchor chain?

greatketch@...
 

Bill R,

I have always set my depth offset so the fathometer reads the actual water depth.  It minimizes the chance for me making careless mistakes in arithmetic because I spend a LOT more time comparing my fathometer reading to the chart than anything else.  

Other people do other things, of course, but I did make the (possibly rash?) assumption that when I talk about "water depth" to sailors they understand how to convert their own fathometer reading to a water depth. If anybody is using the depth under their keel to calculate anchor scope, they have probably already lost their boat.

I guess I was not clear in making my main point. I did not mean to imply that I could anchor with ONLY 60 meters of chain in 10m of water.  I said I could anchor in nearly 10m of depth (@ a scope of 7) without the splice touching bottom. That was apparently unclear, so here is what I meant...

If I am anchoring in 10m of water, and adding 2m for the height of the bow roller (mine is actually 1.6m, but let's round up just for fun!):  I need 7*12=84m of scope.  if I let out all my chain that's a scope of 5:1, and if I let out an additional 12 meters of line, I am at 6:1 and my splice is JUST touching the bottom in dead flat calm conditions.   Of course if I have let out 12 meters of line, there is no need to add extra for a snubber.  

I hope you'll grant me that I wasn't too far off when I wrote that I can go to NEARLY 10m of depth without the splice touching bottom.  

Of course if ALL you have is 60m of chain, then 10 meters of water depth is out of range in anything except reliably mild conditions.

Bill,

I am writing this to clarify something in your recent post about anchor scope. I am sure you know this, but there wasn't enough detail in your post that newbies will certainly need. 

10 meters indicated on the depth instrument is actually 10 meters of water, only if you have the depth Datum set to water depth rather than actual transducer depth, or keel depth. If you have the Datum set to keel depth (as many do), you need to add this to the scope computation. Unless the Datum is set to indicate actual water depth, you are probably closer to 12 meters. You can find information on the Datum offset in your depth instrument manual. 

FYI, I was recently in an Amel that someone had attempted to set the Datum to indicate the depth of the keel. That person then relied on his depth instrument in shallow water, but because he set the Datum wrong, when his keel touched bottom, his instruments indicated 3 meters. When this boat was hauled out, there were more than 10 large chips on the cast iron ballast and a large chips in the rudder.

Additionally, your bow roller is about 2 meters above the water, so when computing scope you'll need to add this to the computation. The easiest way is to add it to the indicated depth.

Also, many of us like to have a lazy loop of chain between the snubber connection to the chain and the bow roller.

Chances are that with 10 meters depth indicated on your depth sounder, you need to use somewhere between 12 and 14 as depth in the scope computation. I doubt that you can get 7:1 in 10 meters of water with 60 meters of chain...I believe that the most that you could have is between 4 and 5:1.

Look here for great information on C-links to connect two lengths of chain. (but look quick!  His web hosting expires soon!)

Batteries again,


Does anyone have any experience or knowledge about the Vmax batteries?

They have two interesting batteries

SLR125 and the XTR-135 125/135 Ah for a group 31 type batteries, with the 135 I would get 540 Ah instead normal 420 Ah a significant difference. Price looks ok 2268 $ for 8 batteries free delivered, cost for the 8 125 Ah 1840 USD delivered. Good prices for AGM batteries

Not very much reviews on internet but a few on Y tube but one do not know who behind the reviews

Re: How much anchor chain?

Bill,

I am writing this to clarify something in your recent post about anchor scope. I am sure you know this, but there wasn't enough detail in your post that newbies will certainly need. 

10 meters indicated on the depth instrument is actually 10 meters of water, only if you have the depth Datum set to water depth rather than actual transducer depth, or keel depth. If you have the Datum set to keel depth (as many do), you need to add this to the scope computation. Unless the Datum is set to indicate actual water depth, you are probably closer to 12 meters. You can find information on the Datum offset in your depth instrument manual. 

FYI, I was recently in an Amel that someone had attempted to set the Datum to indicate the depth of the keel. That person then relied on his depth instrument in shallow water, but because he set the Datum wrong, when his keel touched bottom, his instruments indicated 3 meters. When this boat was hauled out, there were more than 10 large chips on the cast iron ballast and a large chips in the rudder.

Additionally, your bow roller is about 2 meters above the water, so when computing scope you'll need to add this to the computation. The easiest way is to add it to the indicated depth.

Also, many of us like to have a lazy loop of chain between the snubber connection to the chain and the bow roller.

Chances are that with 10 meters depth indicated on your depth sounder, you need to use somewhere between 12 and 14 as depth in the scope computation. I doubt that you can get 7:1 in 10 meters of water with 60 meters of chain...I believe that the most that you could have is between 4 and 5:1.

Best,
