Maybe blistering is fundamentally different from simple osmosis, which is a phenomenon whereby water tends to dilute a more concentrated solution by flowing across a semi-permeable membrane (as in, blood cells swell and pop when placed in distilled water and collapse in saltwater. This would suggest that immersion in fresh water would be more likely to promote blisters than saltwater. I think some of you out there have encountered just such a problem, although saltwater could of course be less concentrated than some component of gel coat. Interesting technical question.

Howard and Bill, The one thing I am most afraid of is not fresh water slime, but gelcoat blisters. Indeed the sailing season here is May-mid October, so 5.5 months. Is the issue with gelcoat blisters mostly from saltwater? Just a dinghy with a set of oars probably won't do: the mooring is about 800 feet away from the ramp where I can get in the water in a public spot, and I don't want to bother my friend by going through his back yard every time I want to go sailing. Or would it? I was thinking perhaps a canoe instead, so I could also enjoy it by itself. Thanks, Andrei. _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats _______________________________________________ http://mailman.xmission.com/cgi-bin/mailman/listinfo/montgomery_boats
