Re: Membrane Tube end caps

I find the endcaps extremely poorly designed and made in such a way that removal because a needlessly complicated struggle. Even the black ones are silly expensive and prone to deterioration over time. The plastic becomes soft at the inside where it's exposed to salt water.

I'm sure there must be better designs for this.

Re: Where to put the life raft

Teun BAAS
 

When replacing my OEM 8 person raft last year I was told similar; you don’t want a life raft much larger than the expected occupancy. Having 2 people in an 8 persons raft makes it also vulnerable to being blown/turned upside down in which case you will never be able to right it again in heavy sea: thus virtually impossible to survive as the top of the life raft can NOT function as a solid bottom.

 

So I got a new 4 person life raft to replace the 8 person ZODIAC. Also – since ZODIA was no longer produced/available & all replacements were deeper it necessitated a welding adjustment to the cradle in the rail.

For what it's worth, I was talking to a coast guard guy about rafts recently. I was about to replace my 6 person zodiac with another 6 person raft. He cautioned that most bail out injuries happen after you're in the raft getting thrown around. He said 2 people in a 4 person raft was probably safer as you tend not to be propelled from one side to the other. It's also lighter obviously when deploying it.

Switch on Bilge Float Tube

Ian Townsend
 

When cleaning our bilge, we noticed the cap had come off of this (see pictures). It is attached to the tube that houses the bilge float and appears to be a switch. But I am not really sure what this is. It's not our float switch. We have the standard version of that. But maybe it's an old high water alarm with relay to the bilge pump? Can someone enlighten me? I need to source or to fabricate parts to cover it properly. The parts that remain are a plastic disc shape cap that used to be attached to something rubber that is either a membrane or a seal, and a piece of a metal gasket.

Re: Membrane Tube end caps

Germain Jean-Pierre
 

Hi Eric, 

I had a pair of white end caps made by EMEK marine and these were not good. (I discarded them after just looking at them)  But even from the factory, immediately after installation, the black ones leaked and were badly drilled out.  Dessalator refused to replace under warranty even when supplied with photos….

I took a well turned end piece to a NZ shop and had a dozen made locally; they are done but I cannot pick them up due to lockdown…. Other Amel owners participated to a small group buy.  (About 60% of Dessalator price without delivery and GST costs)

What I’m most interested in is any modifications done to the tubes, end pieces or complete replacement of the Duo 100 membrane setup to deal with too many leaks.  

Kind regards,


Jean-Pierre Germain, SY Eleuthera, SM007, NZ

Re: Excessive usage of water maker membranes

Thomas Peacock
 

Hi Eric,

No idea. Need to be on more intimate terms with the governor. I heard today from the dockmaster in the marina where Aletes is that a captain of a mega yacht flew in, told the authorities that he was going to quarantine on his boat. They told him no way, and he is now spending 14 days at the airport hotel. Not what he had planned.

My only thought is like others, make certain that there is no chlorine. Obviously, there shouldn’t be if all you do is make RO water. Do you ever put water in the tank from the marina? We often have both RO and shore water, tough to tell how much chlorine, although you can buy test strips. I will sometimes flush with a couple of gallons of RO water drawn from the control panel tap, rather than flush with water from the tank.
 
 
This details some of what can go wrong, including post-mortem pictures. Interestingly, there are several causes for physical damage to the membranes (as opposed to chemical) that might have some bearing on your issue.

AMELIT’s previous (original) owner replaced the OEM DESSALATOR, after 4 years, with the SPECTRA NEWPORT II.

I can NOT contribute anything on the DESSALATOR discussion nor want to hijack this thread.

 

But I do have a specific AMEL question on my SPECTRA NEWPORT II – are there any AMEL (54???) owners also with a SPECTRA NEWPORT II? I would like to Email you with the question/issue.

 

Thanks for the help.

There are times when you must take marina water and thus can only flush with marina water. I find it hard to believe that the makers of the membranes would not have considered this possibility in the boating world. Then again it might be pure science and I must make water in dirty marinas and harbors come what may. I have a good supply of pre filters.

Apologies for the late response.

Please put Nomad on the list tentatively  as we, weather depending (again), may shove off from Martinique of the 24th of April.

I believe with Zoom it can be recorded as well. Perhaps a repository possibility for those that miss the gathering?
Be safe all!
