Re: Bow locker floor replacement.....

Hi Tom,
I cut a trapezoidal opening in the new floor leaving 3” all around.  It’s enough of an opening to work in the chain locker but you’ll still feel cramped.  The floor is solid enough to walk around on without any “give”.

Pat,
Remember that Gross and Net Tonnage on your Ship's Papers IS NOT weight.  It is a measure of volume of cargo a ship can carry that goes back to setting tax rates on shipping. Net is total less machinery space conceptually, but the formulas are a bit arcane. You can get more info on the USCG or NVDOC web pages, which has an easy way to get an approximate measure.

Yours sounds exactly right - my Santorin, which weights some 22000 pounds, or 11 tons has a Gross Registered Tonnage (GRT) of 31 and 28 Net. Again, Registered Tons are cubic volume, not weight.

Re: Maramu anchor and chain suggestions

James Alton
 

Michael,

   Thanks for providing the link for the chain shackle, that looks like a positive way to connect a snubber.    As it turns out I am preparing an order through SVB so this was good timing.  We have always used a snubber since we also consider it to be essential  but I want to have several backups prepared and ready to add if needed.  It seems to be difficult for find Nylon line in Italian Chanderlies for some reason so I will bring more with us on the next trip over.  I have also decided  to try eliminating the original stainless anchor swivel used on my Bugel for the chain to anchor connection also over concerns of it potentially being a weak point though it has never given us a problem.  If I start having problems stowing the anchor due to twists, I will revisit the swivel options but otherwise fewer connections seems like the way to go.

   I think I will go ahead and order the 100m of the 10mm chain and try Tom’s solution to deal with the chain castle problem.  Worst case scenario I can always cut some off if it becomes too much of a problem.

   I just looked again at the weight of 8mm chain and this time what came up was 14kg for 10m.  I might have made a math error or typo in my previous post.

I don't think there will be any chance of it coming loose unexpectedly. I am also using just a standard quality shackle to connect the chain to the anchor. Not a fancy swiveling one. I don't deem those to be necessary and they are a weak point, and you normally cannot check the swivel for corrosion. But opinions differ about this topic.

Using a snubber is always a good idea and I cannot understand the people not using one. Just keep in mind that a snubber has a maximum extension, too. If that is reached in heavy weather you are back to the point where any additional force will reach the anchor unmitigated. But then there is not much else you can do at that point but pray.

I took the 13kg for the 8mm chain from catalog data. I think it might depend on the actual material used.

Hello, I'm new to the forum so i want to appologize if I post in a wrong group.
The question I have is: I am interested in buying an Amel Euros 41, build in 1975, well taking care of for all these years. But I'm curious if there are some specific points that have to be looked after. I have a general idea what to check out but it is a general idea suiting all sailing vessels.

Kind regards,

Re: Bow locker floor replacement.....

karkauai
 

Hi Thomas,
I also had the unfortunate experience of my chain getting rusted into a ball.  I managed to get it out with a pneumatic chisel while pulling the end of the chain up with a halyard, but it took about 40 man-hours.  I acquired the nickname Rusty for that project.

A friend’s slight 13 year old farm kid is great with all kinds of tools and heavy equipment. He crawled into the chain locker.  He used a vibrating saw to cut a 4”x4” hole in the false floor and found the area below it completely filled with mud and small particles of rust that he was able to remove with a shopvac.  We screwed an 8”x8” piece of StarBoard to the top of the cut out that keeps it from falling back into the bottom.

I was surprised that the exit hole where water leaves the chain locker was located just below the false floor.  So that space stays full of water all the time.  Not sure why the hole wasn’t at the bottom of the bulkhead at the V of the hull.

 I have since had to replace the floors of the bow lockers (there are a couple of threads here about this).  I used a very strong light weight sandwich board material (sorry, don’t remember what it’s called).  I cut access ports in the new floors and made them water-tight (the frames are screwed down on the remaining sandwich board with a rubber gasket, so access isn’t easy, but it is there if you need it.

Thanks to all for the words of wisdom I'm getting. Because I wasn't that careful with debris, the dust and wood chips combined with the mud already there to clog my anchor locker drain (entering through the permanent grating). While I was able to access the line to clear it out both from the T connection near the shower and the drain fitting inside the locker, getting the mud/other stuff out requires one to be inside the chain locker with some kind of vacuum poked through the grate, if it's really clogged. Which brings me to my question. I'm leaning towards an ingress hatch so I can get inside the chain locker. Just continually blowing the clog free with water/compressed air seems to be kicking the can down the road a bit. Thoughts ? Note- Since I achieved the age of 6, I lost the ability to pass through the bulkhead access door. I'm wondering if part of the reason my previous 5 year old chain became a ball of rust was incomplete drainage from the locker. I can't say I regularly emptied enough chain out of the locker to allow for a visual inspection. 


Re: Hawse Pipe Replacement

Thomas Kleman
 

Thanks to Mark for agreeing to post some pics for me. Today I installed my epoxy resin hawse pipe header/fillet under the windlass. The throat fits in my 4 inch PVC pipe, and it has a wide fillet for the back starboard windlass bolt, which now needs to be longer due to the 10 mm height of the fillet. It's held by 7 screws and half a tube of 5200, as well as the windlass bolt. The residual glassing from the original Amel hawse pipe made it difficult to get the mounting site perfectly flat; the windlass wires complicate getting a grinder in there. Eventually a wood chisel did the trick.

Since my crafter side is activated now, I'm going to make an epoxy resin sacrificial insert for the pcv pipe mounted where it exits the floor to help it last a bit longer. 


Re: Maramu anchor and chain suggestions

James Alton
 

Michael,

   Those are some interesting solutions that I have never heard of.  Apparently a lot of thought has gone into how to deal with chain castles.  I really appreciate your input on this.  Did you read Toms simple solution in the next post that has worked for 20 years for him?  I should have thought of that but it never occurred to me.

   Yes, I understand what you are saying about how having more weight in the rode will provide more catenary at the same load, all true.  Of course in higher winds even heavy chain will as you say begin to act like a rod so at that point having a really good snubber that won’t detach when the all chain rode is wanting to act like a rod is really important.  That is another subject that I have been studying since I have had so many chain hooks pop off when conditions got rough and they were really needed.  I have been tying my snubber to the chain in stronger conditions since the caribiner type hook that came with the boat does not look like it is strong enough for strong conditions but at least it never pops off the chain.  The icicle hitch seems to be a little better than a rolling hitch to make this connection but I still worry about the line working free.  I am open to suggestions. There is a lot to this anchoring business. (grin)

   Assuming a proper snubber handles the surge loads, would the same weight  of rode in 8mm or in 10mm provide the best holding?  I think that if this was the only issue that the 8mm would be the clear winner due to the longer scope but of course it is never this simple.  What options are there for instance to attach line to the 8mm that would be as strong as the grade 80 chain?  And what about the strength of the shackle to the anchor at the other end?  Those concerns bring me back to probably using the 3/8” chain.  And of course in a tight anchorage with limited swinging room so that scope is limited, the heavier rode would be better I think.  

   You might check the math on the weight of the 10m of 8mm chain, unless I have made an error (quite possible) I think it is a bit over 16KG so about a 7 KG difference per 10m.  

    I have learned a lot from this discussion, thanks!

Hi James,

I _think_ there should be enough space in the locker to install such a partial bulkhead. But remember that the locker hatch is not that big. So I imagine it will be a pain to both install the bulkhead and to put the first 20 m there each time you have used them. That said it might still be a feasible idea.

There are also other possible technical solutions that might or might not work like:

and
https://www.sailmagazine.com/cruising/anti-chain-pyramid-rod
So far I didn't try either of it.

Using 8mm chain would probably eliminate the problem alltogether but it comes with a big caveat:

As I pointed out earlier, with the smaller chain you also loose a lot of weight. While this is a desirable effect for the boat trim (more for light deplacement boats than for an Amel), it is abolutely undesirable when the chain is NOT in the locker but in the water.

10m of 10mm chain weigh about 23 kg while 10m of 8mm chain weigh only 13kg. For an anchor chain weight equals to damping. A lighter chain will come stiff like a rod much earlier than a heavier chain when swell and wind increases. As soon as the chain is solid stiff the damping and force absorption cease to exist and the full force of wind gusts and swell will take effect on your anchor thus increasing the danger for it to break out considerably.
This not so much a problem in light conditions, but in heavy weather it can make a big difference.

I consired switching to a 8mm Chrome Duplex chain myself but gave up on that thought when I realized the consequences.

The link is to a well known UK metallurgist who also lives on his sailboat, usually in GR.

I think you’ll like what you read…


Additionally, if you don’t mind the ticket price, think of a ULTRA anchor.  Their swivel is perfect for avoiding contact with the bow.


Good luck

Hello Maramu owners,

  I am not at my boat currently so need some help.  Can Maramu owners suggest modern anchors that are known to fit the original Amel anchor rollers on the Maramu?  I would like to upgrade from the original Bugel anchor to something with a bit better holding.  The Mantus,  Spade and the Rocna are of interest to me.    I am concerned about the tendency of the anchor to strike the bow when being stowed and how well the anchor stows in the original Amel hardware.

  I am also planing to increase the chain length to at least 100 meters.  Has anyone switched to high strength (I believe it is grade 80?) 8mm chain to help keep the weight and the chain piles down as compared to the 10mm?  I am not concerned about not being able to regalvanize the chain which I understand can weaken the grade 80.

  Short term cruising will be Croatia and Greece.  Hope to be in the Pacific in 4-5 years and I seem to recall suggestions to consider even more than 100 meters of chain?   

Thanks for any insight and suggestions.

Re: Maramu anchor and chain suggestions

Tom,

   I really like your solution.  It sounds pretty foolproof, just a bit of hands on work if you are using more than 200’ of your chain!  Thanks for the idea, I like this much better than adding the bulkhead.  I am also still considering the 8mm chain idea.  I feel like weight put into the anchor adds more holding power than putting it into the chain.    I am considering both the 85 lbs and the 105 pound Mantus.   The 105lb. Mantus is so wide that I am a little concerned that I might loose a degree or two on the wind from the windage!  (grin)  Glad to hear that your Bruce is treating you so well.  Thanks for all of the thoughtful and helpful input.
