Re: [Amel Yacht Owners] Re: Xantrex battery monitor
Regarding "Lithium" batteries....
The battery in your phone, tablet etc etc is Lithium ion. The Tesla batteries are made up of hundreds of Panasonic lithium ion button cell batteries The "Lithium" batteries that people are talking about for use in boats are not these. They are Lithium iron phosphate (LiFePO4) batteries - very different. As Bill rightly says, ANY change in battery technology will require a reassessment of all your charging equipment to verify whether or not it is compatible with the proposed battery technology. For example, both our Victron 100A and Promariner 30A chargers have settings for LiFePO4 batteries but neither our engine alternator regulator nor solar MPPT regulator have these settings. This is important as the charging regime for LiFePO4 batteries is completely different than lead acid based batteries...no float phase is one example. Advantages of these LiFePO4 batteries are: Constant voltage during discharge the ability to run them completely down and then recharge again - resulting in nearly 100% useable capacity (eg if you have 600Ah lead -acid batteries you can only reliably use about 25% of that capacity, so to have the same capacity with LiFePO4 you only need 170 Ah...a great space and weight saving. Disadvantages are: Price - they are still very expensive Different charging requirements that my require new equipment to be installed. For further information there is a long, long thread on Cruisers Forum which is very detailed. Cheers Alan Elyse SM437 |

I agree with you. The cost right now doesn’t make much sense. But the cost and safety of lithium is dropping substantially and it is the future. So I like keeping abreast of emerging technologies and it doesn’t hurt to go through the exploration exercise. The fact is that solar is an addition/change to Amel boats that has reaped rewards for it’s adopters. I see the same happening with Lithium. But as you say, it is not just changing batteries - it’s everything associated with it. So the cost would be roughly $20K but you would end up with more usable ah. Don’t know that it would be worth it for most if not all cruisers. I can see the cost coming down substantially as it has over the past 5 years. If it was in the $10k range, then for me it would be worth the investment to get faster charging (saving money on running the generator), lower weight (1/3 the weight), more consistent power release, among other benefits. But as you, I don’t think changing anything on an Amel is smart. Must be a clear and decided advantage/gain for it to make any sense (like solar panels now). Thanks for your feedback. Take care, Rick Gutierrez

Re: Dessalator Fuses
Hi Ian,
Our dessaltor setup has a 40A cct breaker on the box in the engine room to the right of the dessalator membranes. I don't knoiw if there is a fuse in the 24V solenoid control line or not. BUT I don't see how you can have 24VDC on the motor but not on the solenoid. Where are you measuring ? The way the system is wired is the switch on the dessaltor control panel in the galley directs 24VDC positive to the coil connection on the solenoid. The other side of the coil connection is connected to the 24VDC negative that is wired directly to the motor. The big terminals on the solenoid are 24VDC positive to the solenoid contact and then 24VDC positive to the motor. When the dessaltor control switch is OFF, you should read 24VDC between one of the big solenoid terminals and the 24VDC negative on the motor...if not, then the cct breaker has tripped or has failed. When the dessalator switch is ON, you should read 24VDC from the coil contact on the solenoid to 24VDC negative on the motor .... if not then there is an issue in that control cct wiring. If you do read 24VDC at the control contact then the solenoid should have energised and you should read 24VDC on both the big terminals on the solenoid....and of course the motor should be running....if the motor is not running then there is an issue with the motor. If you still only read 24VDC on one of the big terminals then the solenoid is not working. I wouldn't advise hitting things with hammers. There has to be a reason the system is not working. Let us know how you get on. Cheers Alan Elyse SM437 |

Re: [Amel Yacht Owners] Re: Xantrex battery monitor
John Clark
Hi All,
Bill Rouse is right to warn us about the interrelated nature of the systems on our yachts. My boat has AGM batteries and has had them through several replacement cycles over the last 16 years. She is an older SM which has a functioning shaft alternator that charges batteries while sailing, and works great. Additionally there is a belt driven alternator on the main engine...and two 220v powered battery chargers that need to be started in a sequence to play nice together. Previous owner left lots of instructions ...which were developed over the nearly two decades of ownership. The chargers are programed for AGMs and to talk to each other. The cabling is set up and sized for maximum charge rate....if I changed to lithium batteries the chargers would require reprogramming...if they even have a lithium battery charge profile, the alternators would need new regulators that monitor charge state of batteries, the battery bank monitor would surly need to be replaced, and the cabling would need upsizing to take advantage of the high amp charge abilities of lithium batteries. All that said if I had a blank slate and had to build from scratch...perhaps I would try lithium but not now when I would have to toss perfectly functional infrastructure. By the way. The shaft alternator at 8kts carried the load of the full nav suit, two frig/freezers, radar, and an ice maker...yes I like my glacons. Does anyone know if allowing the propeller shaft to free spin causes appreciable wear to the c drive seals and bushings? John Clark SV Vent de Soleil SM 37 Le Marin, Martinique |

Bill & Judy Rouse <yahoogroups@...>
Hanspeter, Remember, I am the guy that is 100% Amel and I am also the guy that warns of change...My job is a hard job, but somebody has to do it. 400 hours/year comes from cruising 12 months a year, and actually going places around the world - without ruining sails which are just as expensive as an engine. Most of the people that I know with low engine hours have ruined sails and/or low annual miles. You are probably an exception. Maybe one day, you will catch up with me. 🤔 Bill X-BeBe On Thu, Mar 16, 2017 at 3:00 PM, 'hanspeter.baettig@...' hanspeter.baettig@... [amelyachtowners] <amelyachtowners@...> wrote:

Ho Bill you are serious I knew but an average of 400 h engine per year for bluewater sailing; means about 2400 nautical miles with engine in a year, I never did that... ok, fair ,different people different things, and pls be not so hard with your opinions to all others, mainly new SM owners, not for us oldys even from the source of Amel.. technology changes quickly so Lithium batteries are a thema which we have to consider. Nothing to do with batterie chargers, alternator, electronic monitors etc. even the price will drop essentially in the forecoming years. It will be the future .

Re: Bilge / Sump pump
danielmfrey63@...
Bilge Pump Replacement - After 25 years of heavy duty I had to replace HEUREKAS (Santorin No 64) bilge pump. Unfortunately the original is not available in a 12V version at the moment. And nobody knows what time frame the Italian manufacturer has. So I decided to install the RM 69 bilge pump. It can be bought here: https://www.svb.de/de/rm-69-faekalien-und-bilgenlenzpumpe.html AMEL purists: relax! The RM69 brand is well known to AMEL. It has been a supplier for many years. The RM69 is much stronger than the AMFA pump. And it sucks in the water from the bilge, even when the vacuum is not perfectly tight. I will tell you in 25 years whether it also lasts as long as the AMFA. Daniel - SN 64, HEUREKA |

Re: [Amel Yacht Owners] Re: Xantrex battery monitor
Bill & Judy Rouse <yahoogroups@...>
Rick, The other side of the lithium issue for an Amel built for cruising: We all need to take extreme care when considering changing the design of integrated systems by changing one component of the system. The batteries are one component of a system which contains:
Yes, lithium is great and could be great in an Amel, albeit, not as available or safe as what we have. But, if lithium batteries are not integrated into the boat with correct chargers, regulators, alternators, MPPTs, etc., you could create a huge problem. And, if lithium is properly integrated into an Amel, how much does it cost to change everything? To get all of the advantages of a 660 amp 24VDC lithium house bank wouldn't you have to have 300 amps @ 24VDC chargers? But, most Amel owners are cruisers. Amels have generators which will be run with regular frequency to power convenience items like clothes washers, watermaker, etc...a great time to charge and/or top-off your conventional batteries. The main engine is also run with frequency by cruisers on Amel yachts (averaging about 400 hours/year)...this also tops off the batteries. Some Amels have solar and/or wind charging systems which charge at a slow pace, but for hours...not what a lithium battery wants, but fine for what we have. I own lithium batteries. They are in my tablet, phone, laptop, camera, etc. I would never recommend the extensive change in the boat's electrical system that lithium batteries would require.

Looking for diagram or part number
Steve Morrison <steve_morrison@...>
Hi all,
I am at home in Cincinnati (away from SM #380), and have the gearbox to the mainmast furler on the counter here as I try and disassemble it, clean it out, lubricate it and change out bearings. Do any of you have a diagram of the gearbox, know the part number and manufacturer of the gearbox, or have experience opening up and overhauling the gearbox that can share some information. I tried to have Lauderdale Battery repair the motor on this unit but they were unable to and so as I await a replacement from Maud, I thought I would clean, lubricate, reseal, and paint the gearbox. Also looking into installing grease fittings on the gearbox as others have mentioned. Any assistance or photos from your own tinkering would be useful. Also Maud has said that the original Leroy Somer motor is not available thugh they have a suitable replacement motor that she has ordered for me. Doe anyone have this newer/different motor on their Super Maramu? All the best, Steve Morrison SM #380 TouRai Brunswick, Georgia |

Dessalator Fuses

Our D50 stopped working after 45'. Sanded the solenoid terminals. Serviced the brushes. Knocked solenoid and motor with hammer. 24V is at the motor but not solenoid. I figure broken solenoid or a blown fuse. Can't find the fuses though. Anyone help me find where they are? Ian Townsend SM153 Loca Lola II George Town, Exuma |

Re: [Amel Yacht Owners] Tiny lights on 24V panel
Bill & Judy Rouse <yahoogroups@...>
Wow! $150 for LEDs! When I was in Guadalupe years ago, I bought several different color 24VDC LED panel lights a/k/a "idiot lights" for a few dollars each in a general Marine Supply shop. Although the panel light on the 220VAC panel got dimmer over the years, I did not replace it, rather I installed a digital meter for volts, amps, Hertz. I would imagine a Google search will help you. Or ask Sri or Alexa. CW Bill Rouse Admiral, Texas Navy Commander Emeritus Galveston Island Sent using Google Fi +1(832) 380-4970 On Mar 14, 2017 20:52, "divanz620@...

Re: Xantrex battery monitor
devaxmangor@...
Late to the party here Thomas. I just came across a youtube video by Gone with the Wynns talking extensively about Lithium Iron batteries. Sounds very attractive, especially the shorter charging times, lighter weight, consistent output, etc.etc .etc. Price is still high.
Here's a link to a solid company that appears to have excellent customer service and international support: I'm still 4.5 years away, so I can't share direct experience. But here is a blog post with more info from the Wynns: At the bottom of this post is a link to another very tech blog couple, technomadia, who are switching from RV to boat. They go into very great details about numbers (also their cell info as well as WiFi stuff is great). Anyway - hope this helps and is relevant. Cheers, Rick Gutierrez Los Angeles, CA |

Languedoc looks to be in exceptional condition from the photos. If you happen to stop in Titusville, Florida on your way up, drop me a note at: Lokiyawl2 at aol.com. The marina basin is well protected. I would very much like to see some of the upgrades that you have done and perhaps take some measurements of the helm seat since I need to scratch built one for Sueno. I have access to most things marine and a shop close by if needed. The cove stripe is a nice touch btw. James Alton SV Sueno, Maramu #220 (also a 1987 model)

Re: [Amel Yacht Owners] provenciales
greatketch@...
Jeff,
Having just stayed at both, I would recommend Blue Haven if you were going to leave the boat unattended. At Turtle Cove we were side tied to a rather rough bulkhead. Not terrible, but the fenders did take a bit of regular tending to keep the boat safe from pilings and harsh edges. At Blue Haven you'll be in a proper finger pier slip. And all the amenities that have already been enumerated for you! Of course if you are not there... they don't really matter... We left Turtle Cove because we felt "bottled in"--only being able to go out sailing on a high tide. We are a bit different than a lot of cruisers because we frequently go for day sails and day fishing trips. So not having free access to the ocean was a serious drawback for us.
