Re: Storm tactics
Hi Mike,
toggle quoted messageShow quoted text
We got caught in a slow moving front last spring with 35-40kts with gusts over 45 from the N (where we wanted to go). We didn’t want to run S with the storm and lose a lot of ground, and tacking into 8-12 ft seas didn’t seem like much fun (and probably wouldn’t have gotten us very far N). We hove to for almost 48 hours with a small handkerchief of jib and about 1/2 of the mizzen, drifting directly downwind. The slick we created to windward calmed any breakers (only one small breaker slapped the boat in all that time), the motion was benign, and we lost only 50 miles in two days. In thunderstorms with high winds, I reduce sail as the storm approaches, and if there is room, I keep the wind on the aft quarter until it abates. It often changes direction continuously as the storm passes, it can take an hour or more until the prevailing winds return. Kent SM 243 Kristy

Re: Water maker Questions
Bill et al,
World Health Organization to the rescue; but anything <500 ppm is good. "TDS is a measure of Total Dissolved Solids in Water which comprise of inorganic salts, principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides and sulfates, and small amounts of organic matter that are dissolved in water. TDS in drinking-water originates from natural sources, sewage, urban runoff, and industrial wastewater. Concentrations of TDS in water vary considerably in different geological regions owing to differences in the solubility of minerals. According to WHO report on Drinking water standards, NO health-based guideline value is proposed for TDS in Drinking Water which essentially means that human body can ingest any amount of TDS in water without any health impact. Now the question is …Why high TDS is considered bad in Drinking Water? The simple reason is the palatability or taste! Yes, you heard it right. High levels of TDS in drinking-water may have a certain objectionable taste because of salts. The palatability of water with a TDS level of less than 600 mg/liter is generally considered to be good; drinking-water becomes significantly unpalatable at TDS levels greater than 1200 mg/liter. Also, TDS may be high because of certain chemicals which are harmful and hence purification is required to eradicate them. However, this is not a concern in naturally available water. Thus, we can drink the water of any TDS level if it is devoid of harmful pathogens, chemical, and other unacceptable impurities.Hence…high TDS does not lead to any health problem. The presence of high levels of TDS may also be objectionable because of excessive scaling in water pipes, heaters, boilers, and household appliances. Alternatively, water with extremely low concentrations of TDS may also be unacceptable because of its flat, insipid taste.Most purification techniques such as filtration, membrane processing or sedimentation aim to eliminate the impurities that form high TDS. Water is treated or purified to maintain palatability as well as purity in terms of microbial and chemical composition. It has nothing to do with TDS or mineral content. Purifiers in the market with TDS modulator or a Mineral Booster are just for marketing promotion for naïve customers and do not have any rationale behind it. To know more about TDS in drinking water, go through the following research published by WHO.WHO Guidelines for drinking-water quality -2008

Re: Dessslator HP hoses
eric freedman
Alan, You can go to any hydraulic shop—they can make you up the hoses for you. They are usually rated at 4000 psi and have swaged on fittings. Probably for 50-60 dollars. If I remember correctly the fittings are called JIC fittings. I have been using these type of hoses for my stove, the hydraulic brake hose as a spare, and my watermaker. They do have drinking water quality hoses on special order , however I use regular hoses and my TDS meter always reads around 200.

Here is the fitting in steel- granger might have it in brass or ss.

Hi All, im about to order new HP hoses from the dessalator rep in the US. The end fittings are reusable and so you only need to buy the hose unless like me one of your ends are damaged.

Re: 1986 Amel Maramu 46 Mainsail Furling Motors
"... if they would just give us the spec of the motor - or an equivalent..." They don't do things that way, and Martinique is the wrong place to ask because they order all of the parts they sell from La Rochelle. If you follow the instructions I gave you, you will get an answer, but since it will require them ordering a part for a 33 year old Amel, your request probably will not get the priority that another will get ordering a motor for a 15 year old Amel and that part is still stocked by Amel. Note, that one part of the instructions I say, "In an emergency you can phone SAV at +33 (0) 546 55 00 75." Call them. French or English.

Hi I own a 85 Maramu and have had to have these motors repaired. They may be rusty but a good DC motor rebuilder can usually get them working again. They are just a old 12Volt dc starter motor. The problem sounds like a stuck or warn out brush. I don’t know where you are but there is usually a rebuilder that can help you out. Good luck. Fair winds Bill Fletcher Tahitian Dream Maramu 179

Samantha Jane Bartlett
Thanks Bill,
We have asked for a quote from both Amel in Martinique and SAV in France - my husband has spoken with them in French (he's French) and we are still getting no joy. I understand it's a 33 year old boat but if they would just give us the spec of the motor - or an equivalent, we can work with it! He's going to try and call again tomorrow to France... but this has been going on a long time now and we're no further forward. Our old motors are just too rusty to get any info from!

Re: Auto pilot for a Santorin 46
smiles bernard
Hi there
toggle quoted messageShow quoted text
Just some thoughts related to reliance on the autopilot. We bought our Maramu to sail short handed, long distance with young kids onboard and this led me to consider our reliance on a single autopilot. The electric autopilot has been excellent but I did want a reliable plan B. I looked into replicating the very nice SM dual autopilot system with the addition of a linear drive unit on the steering quadrant. In the end, for true resilience (ACU, control head, rudder sensor, drive unit) the costs and instal complexity led me to a wind vane instead. I’ve used various wind vanes before on long trips - both servo pendulum and independent rudder systems. In each case the vanes quickly became one of the most essential things on the boat. Almost zero maintenance, very robust and zero electronics and battery draw and they work better as the wind blows harder. In the end for our Maramu I chose a Hydrovane as it operates independently of the boats steering system and works well with a center cockpit arrangement. It’s has been steering our boat faultlessly since we installed it. In fact I’ve hardly used the Raymarine autopilot since we added the Hydrovane. I believe the windpilot Pacific 2 is similar in nature in that it steers the boat whilst the main rudder is locked off but Ive not had the pleasure of trying one out yet. . I wonder if the SM is getting a little too big for a wind vane. Anyone tried a wind vane on the SM? All the best Miles Maramu 162

Re: Water maker Questions
Tom,
250 ppm is what you are looking for as far as TDS goes. The EPA’s recommended maximum level of TDS in water is 500 ppm. Note, it's not a limit, just a recommendation. The 500 number you saw may have been for Conductivity (proxy for Salinity) which is measure in microSiemens/cm (µS/cm). You want that between 200 and 800 and I think Dessalator claims 250 TDS and 550 Conductivity in their marketing material. I picked up this kit from Amazon to test it: https://www.amazon.com/gp/product/B077SQTKH4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 I have no idea how accurate it is, but it gives me reasonable results for tap water, distilled water, Chesapeake Bay water and watermaker water so it appears to be accurate enough. -- Mark McGovern SM #440 Cara Deale, MD USA

Re: Water maker Questions
Might "not taste anything," but most people cannot tolerate their drinking water with anything over 500ppm. Most people will retain water at 500ppm. Before you start abusing your body to save a few euros on membrane costs, you might want to ask your doctor. Tom, I can't answer your question about "acceptable" in your situation because I don't believe you gave specifics in ocean water. Watermaker output depends on many things, including pressure, membranes, pressure maintained, salt content of the water, and even temperature. Your D60 new membranes should produce 1 liter a minute +/-10% when making freshwater from ocean water and a pressure of 50 BAR on the outside of the membranes. If your membranes are 2 years old, the TDS should be around 250 after about 5 minutes of production. In 1 hour the TDS may improve slightly. It is true that Dessalator has waffled on what is good quality in terms of TDS. The WHO states 500ppm or less. Spectra Watermakers say 1000ppm, or less (a laugh everytime I hear this). Judy and I changed membranes about every 4 years because we could definitely tell when the TDS moved above 325-350. I hope this helps.

Re: 1986 Amel Maramu 46 Mainsail Furling Motors
BE CAREFUL. A Maramu is a 12 volt boat and a Super Maramu is 24 volt. The motors are different: Apples:Oranges. Samantha, it may not be possible to replace with OEM devices on a 30 year old boat, but if anyone can do it, it is Amel. You should follow the instructions on the attached to order a part. If you are asking Amel where you can buy the motor or how to contact Leroy Somers, you are absolutely asking the wrong question. You should be requesting a quote and you should include all of the steps outlined in the attached. Best, CW Bill Rouse 720 Winnie St Galveston Island, TX 77550 +1(832) 380-4970

Hi Tom,

500 ppm is considered the upper limit, anything below that is acceptable for drinking water. However once the membranes get to the point of delivering either 500ppm of close to it they are arriving at replacement time. 280 is acceptable and of course at start up you will see higher levels. My duo 60 has manual controls and I run product water to waste for a couple of minutes after start up. So long as the tds goes down to an acceptable quite quickly dilution would deal with it. 0.75l/m is not far off 60 l/h the and if you give the watermaker some long use you may find you get it up there. So in summary. 500ppm is the upper limit but you wont die if it is a little higher. Anything in the mid 300 and below is quite acceptable. Once my tds gets over 400ppm on a regular basis I start planning for replacement. Like anything, the best treatment is regular use. Regards Danny SM 299 Ocean Pearl
