Can you explain why the percentage of boats that have blisters in
fresh water is higher than in salt?
I know that osmosis occurs faster in fresh water...something to do with
density/salinity factor I think.
Can you explain in a clear manner?
Thanks,

ahh that'll do but to put it as simply as possible, fresh water is
lighter and thinner than salt so it gets in easier.
Thinner? You have some viscosity data to back this up? More likely fresh
water exhibits a higher osmotic pressure because the difference in water
concentration is greater in fresh than brine. (osmotic pressure being
proportional to the differences in concentration on either side of the
membrane)
Very close, but the osmotic pressure of fresh water is low.
I expected a blsitering reply from you...
