Are boats faster in Pacific waters? Are boats faster in sal****er? Seems
to me a boat would ride higher in sal****er and thus be faster in an
equal sea state.

Boats do float at different heights in fresh vs. salt water.

Check the plimsoll lines on tankers and container ships, for instance.
They are calibrated for fresh and salt, and also for differences in
water temperature.

That said, one has to wonder whether the resistance of the denser
medium wouldn't just about cancel out the tendency to float the vessel
slightly higher. For most boats, the difference is probably measurable-
but so slight it would only be significant to the most extreme nit
pickers.

Chuck, the boiled peanuts will be in the mail Monday. Found them in
Richmond. Guaranteed Virginia peanuts. You better not eat for a few days
and build up an appetite!
