There are differences in the Specific gravity of salt vs. freshwater,
and Atlantic vs.Pacific waters. Wondering how this effects boat speed.
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.

Maybe in a displacement boat. But I doubt the difference would be noticable
on a planing hull.

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.

I've experienced a consistent 2 MPH delta with a planning hull at WOT
from fresh to salt. That translates into a 6% difference. Even though
that's been my observation, it just doesn't seem right. I'm also curious
about the East/West Coast speed delta. Suspect there is one. Bet there
is also a corresponding fuel penalty for displacement hulls due to this
effect. Perhaps one of the boating rags will publish some data on this
in the future. Would seem the mix of fresh and salt you have in your
area would have had someone looking into this...

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!

How do those ocean-going boats ride in the dangerous deep waters of
Derby, Kansas?

Bring me up to speed on this. Why do you guys claim he lives in Derby,
Kansas?

Because Derby, Kansas is home to a 500-bed looney bin, that's why. All the
rooms in the looney bin have been designed to look like a boat cabin,
complete with portholes for windows, hatches for doors, a fold-away rack for
a bed and fake throttle controls.
Residents of the looney bin spend countless hours watching recorded sea
tales on a big screen, HD TV.

i bet he pukes them all - wanna bet? :)

Well, hopefully he won't open them all at once!

CHUCK - if they make you puke, send the remaining ones back to me!

Now, I'll bet he doesn't puke. What'll you put up against some genuine
Virginia Boiled Peanuts? [NB: If I lose, I'll have some to pay off the bet
with!]
