Thanks everyone! My setup has me in 4 groups of 100AH 12V Battle Borns @24v (400AH). I have each group's positives and negatives aggregating to corresponding bus bars that then lead to the battery

Re: A question about coppercoat
We put our own copper coat on in Trinidad, just the two of us. In the heat it did need thinning down. We did a third of the hull at a time. We did not put a barrier coat on as it is an epoxy mixture

Re: A question about coppercoat
Can coppercoat be applied by an owner or does it need to be applied by a dealer ? If it can be installed by an owner ,what would you estimate the cost of materials would be . I had the impression that

As suspected and expected  did Bills's step by step, literally in 5 mins crisis is over!
Thanks you all. Now another thing, the gear seem to be weak / maybe finished (from before the episode), and

Re: Bow Thruster Amps rating.
Our SM#160 bow thruster draws about 485 Amps when it is running. The exact power calculation is complicated because the voltage is not steady at 24 volts, but drops quickly, and significantly, under

Agree  but this mainly apply to no normal furl / unfurl under normal circumstances. this must be the reason that in 10 years never had this issue before...

Re: Main Furler  Sail stuck / jammed
The trick I have found is to make sure there is plenty of outhaul tension. It needs to be tightly rolled in and out, always keeping the outhaul as tight as possible. Keeping a really good eye on it

Re: Main Furler  Sail stuck / jammed
We furled too loosely and jammed once. We got ours loose the same way. Back and forth, tighten the furler, tighten the outhaul, loosen a bit, then repeat... a lot.

Re: Bow Thruster Amps rating.
The bow thruster is If I recall correctly is 10 HP. 10 hp x 746 watts is 7460 watts without any loss .I would add at east 10% for that, 8200 watts/24=342 amps.
That would be dismissing and loss in

Re: Bow Thruster Amps rating.
Chris,
We shouldn't get into a discussion of what is right or wrong, but rather work to help you. Maybe the math is French math or Texan math, but it will draw as much as around 500 amps.

Re: Bow Thruster Amps rating.
It s forbidden to violat W=VxA, :) so you have to make a deal with 7000 and/or 510. I guess 24 is right.
Possible you can see W on the motor ?

Bow Thruster Amps rating.
Hi maybe someone can help me understand... The Super Maramu 2k Manual shows that the bow thruster draws 7000W and 510A at 24V. Is this correct? If so, how does the math work out? W=VxA is violated
