I would expect that being in a pool, and being in fast running WW would
also make a huge difference. The moving water would be pulling you down
at a much higher rate than the weight of gravity keeping you from
getting out of the pool. HYY


I'm not sure of the meaning of your post, HAA. Are you stating that a full
drysuit will 'pull you under'?

When you are immersed in the water, you have neutral buoyancy...drysuit or
not, full or not, and moving water or not. If your suit is full of water,
you have much higher mass, therefore you cannot change direction, catch an
eddy, or hold on to a handhold so easily, but there shouldn't be any new
forces trying to submerge you.

Moving water doesn't 'pull you down', it only moves you around. The
increased mass would equally tend to keep you from being submerged by a
swirly as it would prohibit you swimming to the surface when you were under.
The primary deleterious effect of having water in your drysuit is that you
cannot get out of the water, and that you are a large mass on the end of a
throwline.

Wasn't it Larry Cable who had a bad swim a couple of years ago when his
drysuit filled with water?

I was thinking that since, as a kayaker, I have a tight fitting neoprene
seal (in the form of a spraydeck) around my waste, that should keep the
water out of the lower part of my suit.
