[ham] Re: [Rhodes22-list] Gas vs Liquid Battens

[Michael Meltzer]

way not use Mylar in the sail, the fancy tape jobs use it all the time. And what is the big deal in the thunderstorm, hydrogen gas
burning in open air is not a big deal, the fire ball should raise away from the boat, the problem is only if the fabric burns with
it, that solvable.
