Re: Bifacial Solar Panels for yachts

I've seen bifacial panels mounted vertically, aligned north-south. They get only reflected sunlight at noon, but generate more power in the morning and evening.

The arrangement yields no more...

Re: Pushing the limits of electric cooking

Yep. Even a 3A draw adds up to a lot, when it's running 24x7.

Re: Pushing the limits of electric cooking

Running an inverter uses power, and loses power. That is, simply having an inverter on uses some power, and putting a load on it loses some in the conversion. Modern inverters are very efficient, but...

Re: Why do we still use cigarette-lighter adapters?

You should have a 10A fuse in circuit. Because the socket itself will start to overheat at currents higher than that.

Re: Why do we still use cigarette-lighter adapters?

12V automobile sockets can handle 10A at most. 120W.

The latest USB-PD spec supports up to 240W, though I've not been able to find a panel mount converter to support that, yet.

Re: Why do we still use cigarette-lighter adapters?

A power converter would need to output as much as 48V to match the highest level outputs in the US PD spec.

But that says nothing about it's input. It's common for these devices to boost voltage....

Re: respirator for bottom sanding

I prefer the ones with full-face shields and space for optical inserts. Mask + goggles just don't work for me.

The next question is what kind of filter, and I've had assumed that any particulate...

Re: Boats with Shallow Draft for Florida, Bahamas, Chesapeake

The usual suggestion is to head to Mobile via the Tenn-Tom canal.

I always feel a sense of accomplishment when I've successfully moved my 6 ton boat on the hard.

Re: Elco electric outboard props?

With a gas engine, exceeding max RPM with a flatter prop is a real concern. With an electric it is not. The motor controller will not exceed safe RPMs.

Re: Elco electric outboard props?

Actually, in my use case I'm more interested in increasing thrust at low speed, than in achieving higher speeds.

Actually, it doesn't. That "peak" corner is supported by a full batten, there's no attachment point for a second halyard.

It may not be clear from the picture, but the luff is on the right, the...

Nomenclature for a square-head sail?

Most boats have triangular sails, these days, and hence their parts are referred to by their well-known names, luff, leach, foot, head, tack, does.

Mine was originally gaff-rigged, and gaffs use...

Re: What kind of traveller track?

The track and the rollers are in fine shape. I may do that, if I decide I need a traveler for the type of sailing I end up doing. Thanks.

Re: What kind of traveller track?

There are padeyes at both ends of the mizzen track, there aren't on the main. They'd be easy enough to add, the main track is on the coach roof, and Curlew doesn't have a headliner.

Googling around about NF 1169 travellers I've seen posts claiming that the Ronstan Series 32 I-beam tracks are dimensionally identical, and their cars and controls will fit.

So that might be...

The way I see it I have four choices:

let the car slide freely, or
lash the car to the center line, or
find control blocks for the existing track, or
replace the track,

Re: What kind of traveller track?

That's the mizzen sheet, yes, and it's necessarily short because it's a very narrow boat - 37 feet in length and only eight foot beam. By the time you've moved back to the stern there simply isn't...
