Re: acrylic dome over the companionway hatch

Peter, the structural acrylic domes used to be cheap from army/navy surplus stores, actually USAF surplus. AFAIK the surplus from WW2 is long gone now and you're going to pay through the nose to have a new one made up or purchased.

There's still new aircraft surplus coming on the market all the time, these days not domes but cockpit enclosures.

Re: acrylic dome over the companionway hatch

Geoff, thanks for correcting me on that. I did have look at the current Jester site and couldn't see any plastic domes so it was up in the air. I'd like to find a pic of the pram hood. I don't have a copy of Hassler's book to hand.

ps - found this ....

Hasler used a canvass on frame device he call a "pram hood" because it unfolded like the hood of a pram. It was round and could be rotated. The idea was that you opened the hatch, unfolded the hood and rotated it to protect you from whatever direction needed, while you peaked out from behind it.

There is a description on how to build one in Practical Junk Rig.

Re: acrylic dome over the companionway hatch

I had one on my first boat. The shape makes for a huge amount of glare, they are easily scratched, and make it hard to seal a sliding hatch.
If I were to make another , I'd weld up a metal frame, to take four flat panels of laminated glass, so they wouldn't scratch up, and could be easily and cheaply replaced. The metal frame would also make it harder for a thief to break in.

I don't know just looking at that makes me feel sea sick, thinking of the distortion it must have.

Re: acrylic dome over the companionway hatch

For a long distance solo/shorthand sail with a windvane autopilot it might be pretty useful.

I've never seen a sailboat that you could steer from inside one of those. Maybe if you had a remote control for an autopilot. Otherwise, you're going to have to go out to do any steering, and then you're going to want a dodger.

It's an interesting idea, but I suspect that in practical use it would not work out as well as the theory might predict.
