[Public-List] Antifouling skirts.

Back in the days of fighting sail, small ships were hauled into freshwater
(up rivers) and sunk temporarily to kill marine borers etc.

I saw a fairly dramatic article in an old yachting magazine showing how
Folkboat sailors in California drew their boats into sunken plastic
envelopes which could be closed behind them. They then poured bleach into
the envelope which not surprisingly killed everything inside.  The boat
would be nice and clean when taken out racing the next week.

I guess people thought in those days that the sea was impervious to anything
we could do to it.
