ACTUALLY PASSAGEMAKING,
perhaps 30 to 40 per cent will be metal or wood

I seem to recall the recorded data shows of boats ACTUALLY PASSAGEMAKING about
2% - 5% or so will be metal, and a % or so wood. Far and away fiberglass is
most common if for no other reason than fiberglass boats are far and away the
most common.

of course, for a given strength boat, a fiberglass boat will weigh less, carry
more stores, be less top heavy, and carry less sails to go faster, but what the
hey.
