Re: [Amel] Re: Power generators


Hi again, Jean,
After reading about the "keel cooler" I have a couple of questions.  Are you concerned at all about leakage of the exchanger into your fresh water tank?  Are both fridge/freezer units attached to the same exchanger?  How much room does the exchanger take up in the tank (ie how much volume do you lose by doing this?)  I've not gotten into my tankage system difficult is it to mount the exchanger in the tank?
Thanks again, this looks like a great idea.

Hi Kent
even easier for the fridge, model keel cool and put the exchanger directly into the freshwater tank .... same system, pumps less!!

Very nice, Ann-Sofie. Another question...Did raising the standing height in the cockpit require that the boom could not be pulled down as far? Did you have to recut the main sail? If the boom can no longer be brought down to a position perpendicular to the main, does the mainsail furl smoothly?
On Kristy (SM243) I have to ease the main a bit to open or stow the dodger extension that covers the cockpit. I would like to raise the headroom in my cockpit but am not sure there is room below the boom.

I am impressed with the efficiency of the water-cooled and reinsulated fridges. That looks like a modification worth doing.

How do you adjust your autopilot in different conditions to make it more efficient? That's something I never considered.

I LOVE this forum! Even with 20K+ nm under my keel I still feel like a rank beginner with an enormous amount to learn. Thais again to all for sharing!

Hi Danny
If you check the album Lady Annila, you will find some pictures of our fixed roof over the cockpit.
To protect us from wind, rain and chilly weather we have a zipper going around the whole roof that we connect 10 panels to, with big windows. If we have all of them closed we are very well protected from the weather. We can take all or some of the panels down. It is free of choice.

The roof is constructed so that you can stand up and navigate and beeing able to see over the cockpit.

The inside hasn't got the final finish yet. But we have mounted a LED tape on the sieling that we adjust with a dimmer.

We have changed our bimini to a fixed roof over the cockpit. On that roof we have mounted 24v solar panel 460 W. Our battery bank includes 8 golfcart batteries providing 520 Ah.
We have changed all lamps to LED, we have changed the compressors to fridge/freeze to fresh water cooling and changed the insulation on them aswell. Which was of big importans for the overall consumption profile

During day time (sailing) we are usually power neutral. Meaning we only have to start the diesel generator for washing or making water.

Our plans is to install a wind generator for additional power during night and cloudy days.

We think that it is better to use the diesel for making speed than making power. So for us, yes it is worth it.

We are intending to do extensive cruising. Staying out of marina's, and primarily living "On the Hook". We have AGM batteries. Filling the battery bank to 80-85% with a genset or hi capacity engine driven alternator is fairly efficient. The last part of the charge up to 100% is not efficient. (Could be many hrs of genset operation at low load to charge up to 100%). For this reasion we will probably install solar panels. AGM's in particular need to be periodically charged to 100% . Also, ask your battery manufacturer what voltage their particular batteries should be charged at. Charging, no matter what the source, at too low a voltage is inefficient, and at too high a voltage is damaging.
Thank You All for the wonderful Amel information. We loved the Joel Potter movie last night.

What my friend Paolo Liberati says is: use all possible system to have power. I.e. it is not a matter of cost benefit balance, when you are on passage, it is a matter of power needs in case of gen set failure. Solar panels never fail, and also windgen. I have sol pan plus wind gen and up to now (in the Med anyhow) now need of diesel genset. Craig with a Santorin and genset says that if you are not too power hungry (led lights etc) you can more safely survive without genset, or with a cheap portable Honda genset for emergencies only and solar panel - at least 2 x 90W - and one wind gen on top of mizzen mast, In total about 1500 euros

Hi firends,
I need your opinion concerning power generator (solar panels , wind generator, water generator) on amel supermaramu 2k; as we know she is a power consuming boat but it is worth to spend money for this kind power generator when we have to use generator for water maker, washer machine and more? In case which of these kind of power generators are more suitable for this boat? One story: during ocean passage I had to turn on generator 3h x2/day, a friend of mine with 2 panels and 1 wind generator has to turn on it 2h x2/ it worth????
Thanks for your help
