Emergency 100A DC fuse

Hi All, I have a mate who, for his sins, is currently cruising on his yacht in the Indonesian Islands. He has a 12VDC anchor winch which has a 100A fuse on it that blew up the other day under load. He has now discovered that the spare that he thought he had isn't actually there. He has various gauge...

Thanks Coulomb,

I'll try and remember that for next time. Fortunately, not too much spam creeps in to this forum, a credit to the moderator(s) I expect.

Outboard Motor conversion

I agree that unless you're keen to spend more money building something that probably won't work as well as an off-the-shelf unit, I'd not go down that path. WRT cooling, most OTS units are direct drive, with the motor under water which makes cooling a non-issue. Lithbattboss, are you referring to a ...

EV2Go's - Lithium Powered Trike

I believe it blows down onto the fins but wouldn't really mattter as it would have quite a decent amount of passing air blowing on the controller fins. Yes, and the only time they probably really make a difference would be when you're stopped and presumably the controller wouldn't be working that h...

One trivial detail that I'm sure you've got weighed off but thought I'd mention just in case: Which way do the cooling fans on the controller blow? Presumably they're blowing with the slipstream rather than against it?

electric 40ft yacht - discussion and advice

Do you carry the 400L of diesel in case you need it for one long stretch due to sail failure? Actually, rig failure is more likely than sail failure - most cruising yachts have more than one set of sails on board. However, if your stick comes down you're a bit stuffed! And Murphy ensures it will ha...

electric 40ft yacht - discussion and advice

How much diesel would you need to carry in a 40ft'r. I would think that your 7-8 Hours on prop drive is at 1/2 power, is that fair enough? So if it consumes 10 litres of diesel in 1 hour you have a measurement of how much energy it takes to power the yacht by prop at cruising speed. Sorry, you'll n...

Ha! The sort of wind generator I was thinking of would do 22 kW in 10 knots of breeze, hence the 40K price tag. With a mast about 18m high you could carry a turbine blade dia of about 14m. Push the thing along at hull speed in any sort of breeze! Then you wouldn't need a genset or solar panels. Sou...

Hi Cram, I currently own a 39' blue-water cruiser, fibreglass ketch-rig with the regulation ICE diesel propulsion.

Hmmm, even "special web magic" doesn't work. Obviously the editor software on this site has a real grudge against apostrophes!

I tend to lean towards plastic for light weight and also corrosion resistance. However, here you may also have to worry about UV resistance, any idea how the plastic will stand up to UV?
