What a dope. There's a simple reason why more blister cases are reported for
salt water boats.
But Loco the Dope is too simple to figure it out.

RB

Perhaps you could explain the reasons for this Bubbles, rather than
just dis the fool.


Sure, Ozzy. More cases are reported in salt water because MORE FG boats are IN
salt water, especially in full season climates. It's not even close.

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)

Even though Marty has the clap, he still sounds smart.

Good one! LOL

Another one who doesn't know what they're talking about when it comes to the

I'd fire up antoher verse of Edmund Fitzgerald, but it's far too
good and far too serious for this forum...

You missed the pun too? You must be tired!

Very close, but the osmotic pressure of fresh water is low.

Or perhaps a faint fairy clap? My memory which may be atfault lo,
these many years, is that "osmosis" and "osmotic pressure" are
labels describing a process which is known to happen and easily
demonstrated and measured, just like gravity and which, just like
gravity, no-one knows what it actually is.

Nav (or others) here's your chance to put the Tadpole down. It's
been a long time since I consciously studied physiology.

Why would telling you someting about science be putting you down? By the
way, osmotic pressure is derivable from first principles (see
thermodynamics).

Awww gets up to about 28c up north..warmer sometimes .


That's warm but is it warmer than the fresh water you are thinking about?

Cheers
