Re: Shore power contactor burnt out
Eamonn Washington
Hi
the good news is that I found a competent electrician in Cagliari, Sandro (tel 3476327483, only speaks Italian), and a place to get the stator rewound (Matta Electromeccanica, tel 070 284 647). Without the helpful staff at Marina del Sole I would not have got this far. The stator weighs about 60kg, the copper had completely melted. The rotor was fine. Matta will charge 500 euros plus 22% VAT for the rewinding of the stator. I will install a double pole 20A breaker in a box in the aft lazarette like Bill suggested. (I don’t want this generator problem again.) Also I will install a manual relay switch in the galley to replace the burnt out contactor in the cockpit locker, with a middle OFF position, rated for at least 32A. Thanks for all the support on this forum, it provided invaluable help. Eamonn Washington Travel Bug Super Maramu #151 Currently in Cagliari, Sardinia, Italy.

Re: Water maker Questions
Thomas Peacock
Thanks to everyone who responded. I can’t say enough about this group!
toggle quoted messageShow quoted text
Some of the suggestions spurred me on to further research, down many rabbit holes. I’d like to give a synopsis of what I learned, read on only if interested, obviously. It was reassuring to find out that the 280 TDS is within a very reasonable range. I am going to clean the membranes, 2% citric acid solution for acid, and 2% sodium metasilicate for the alkaline. I’ll see if that buffs up the TDS at all. Indeed, the World Health Organization, and many governmental agencies has standards for TDS in drinking water, with a spectrum of acceptability, generally over 1,000 being unacceptable, but less than 500 as desirable. However, not all TDS are created equal. TDS is generally anions, cations, and organic molecules. They may occur due to leaching from the ground water table, or agricultural runoff. Where I live (northeastern US), many homes with wells have high TDS due to the wells being in limestone and other similar rock formations. The usual problem from high TDS here is “hard water”, due to excessive calcium and magnesium. This can cause buildup of deposits in plumbing, and poor washing with detergents and soaps. In other parts of the world, high TDS may be due to agricultural runoff, and include phosphates and organic molecules. For our purposes on a boat, TDS reflects residual anions and cations from the sea water. In this case, it is almost exclusively sodium and chloride. So, high TDS not associated with water makers is usually calcium, magnesium (plus or minus organics); indeed, San Pellegrino water, a highly regarded drinking water from Italy, has 1,100 TDS (mostly calcium, magnesium, and sulfate), unacceptable by some standards, but tasty to many people. High TDS on a boat with a RO water maker implies poorly functioning membranes, will be mostly sodium and chloride, and, for many people, becomes unpalatable above 400 TDS. There is not a USA EPA standard for sodium in drinking water, but the EPA does recommend not exceeding 250 mg per liter of chloride. This standard is predominantly an “aesthetic” one, and reflects the salty taste that a level of 250 or above will impart to the water. As per Dessalator’s specs, RO water with a TDS of 250 has 183 mg per liter of chloride. The conclusion that I would draw from this is a TDS of about 350 or above would exceed the EPA’s recommendation. Again, this is predominantly a taste concern, but there are some potential health effects. People with heart or kidney problems may not tolerate it well and retain fluid as the TDS rises.

Re: Water maker Questions
Mark McGovern
Craig,
Your summation lines up perfectly with all of my reading on the subject of Reverse Osmosis. The Mid-Chesapeake Bay area will be our cruising grounds for the next few years so my watermaker will only see brackish water for quite some time. I had read in numerous places online that I would "damage my membrane" if I ran it in the Chesapeake but research from source data shows otherwise. The Filmtec SW30 RO membrane used in our system is clearly NOT the ideal membrane for the Chesapeake Bay, but it does not seem that I will do any harm to it if I operate it at lower pressures like you mention. For any other "geeks" interested in RO information here is a link to the 197 page technical manual from Dupont Filmtec, maker of the RO membrane: https://www.dupont.com/content/dam/Dupont2.0/Products/water/literature/609-00071.pdf Riveting reading for sure! ;) -- Mark McGovern SM #440 Cara Deale, MD USA

Great thread, Thanks all. Question re the JSD and attachment points. We have a JSD and sadly no reinforced rear cleats. What would be the best attachment points on our 54 for both strength and chafe? Also for steering? We carry a good amount of amsteel of various lengths and widths for harness fashioning. (The JSD does come with a harness). I do have an idea but wondering if others have a solution.
As always very appreciated!

Just now looking at that, Eric. I was thinking/hoping that I could run the bridle thru blocks to the jib winches, but haven’t gotten far enough to know if that will work.

Hi All, Very interesting thread. Eric, the Ocean Navigator article did not specify, but for some reason I assumed you used the stock stern cleats to affix the JSD during your hurricane encounter, if so how did that work?, if not did you install chainplates as attachment points. Short of thru bolted chainplates, could one reinforce the existing cleats to allow for their use with the JSD. Tangentially, I am curious, as a relative novice Amel owner how best to 'de pressurize' the sails when in a seaway and building winds in order to reef without stressing the furling motors. Is releasing sheets generally sufficient or is it necessary to head to wind, which would seem to make a boat vulnerable or at least quite uncomfortable to beam seas.

Dave,
We always sheet out so the genoa flogs before reefing in, this way the rubber belt in the furler does not break. We do not find it necessary to change heading.

Re: Monastir Marina

I did haul out my 54, but not in Monastir... - when I was in Monastir I still had my SM GrosDoux.
Right hand guy of Mohamed Mrad (owner of yard) is Amor - he will know all relevant people. Mechanik is Fathi, stainless steel guy is Adel - good werk, but the raw material is not of the best quality. Not everybody is allowed to work there ... caution is necessary when using the canvas guys in the marina. they do a good job, but are never in time. Mohamed the father is ok, Adel who does all the work is very good, but his elder brother who behaves as he were the boss will promise the sky and not know about it afterwards ... fair winds -- Robin Hutter Carré d’As Amel 54 #54

Re: Water maker Questions
Regarding brackish water operation, that's one of those topics that's been burdened with a lot of myth and misunderstanding in the cruising community. It is absolutely OK to run your water maker in brackish or even totally fresh water. It will not damage the membrane as long as you do not exceed the membrane's rated product flow.
Think of it this way - the "green" zone is the pressure at which the membrane is passing it's rated flow of product water. If that is exceeded the membrane will start to tear apart and fail. Our pressure gauges happen to show a "green" zone for sea water and that's in the range of 800-850 psi / 55-58 bars which gives you your rated output for sea water. However, the "green" zone for water of lower salinity is at a lower pressure. So, for example, the fresh water "green zone" is only about 150-200 psi / 10-14 bars for the same rated output, and the brackish water "green zone" will be somewhere in between, depending on its salinity. The proper procedure for brackish or fresh water, then, is to bring the pressure up slowly until you are getting the rated flow of product water. Don't crank it up to the sea-water "green" zone or, yes, you will damage the membrane. And running sea water at 950 psi (65 bar) may shorten the life of your membranes, although that may be OK in the Med with it's very high salinity vs., say, the open Pacific or Atlantic as long as the product flow is correct. I'd guess the idea that running your water maker in brackish water will damage the membrane probably stems from having our pressure gauges show a sea-water "green zone" - some people have cranked the pressure up to that "green zone" in brackish water and damaged their membranes and hence the misinformation starts to circulate. Bottom line though - feel free to sail up the Guadiana or lock into Loch Ness or sail the Great Lakes - you can make water in any salinity - just don't crank the pressure up to the sea water green zone. Cheers, Craig, SN68 Sangaris

Re: Monastir Marina
Robin E. Hutter
I personally used the travel lift at the Monastir marina twice with my Super Maramu and I have seen a 54 on the hard there - you just have to remove the back stays.
The yard is good - try to get a quote before hand - they will stick to the quote given (at least did in my case), however it is not easy to get a reply from them by mail and it might help if you know somebody there to get things rolling. You have to check their works, but they know Amel very well indeed as a lot of French Amels go there. a Personally I did not like the port de pêche as safety is an issue there in my opinion while Cap marina Monastery r is very safe! fair winds -- Robin Hutter Carré d’As Amel 54 #54 www.sailing4ever.com
