Top Speed Considerations
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 saltwater? Seems
to me a boat would ride higher in saltwater and thus be faster in an
equal sea state.

| restaurant quality refers to the quality, type and size, not the
length of time its been frozen. i picked this stuff up at .25¢ a
pound from a distributor for the exact reasons you stated. i didnt
expect him to eat it. for john, if he actually want to eat it, i would not send him bait. i
have a source of fresh frozen, restaurant quality squid that i would
send him. |

| neither - the effects would be negligible, if they were even
measurable. |

| Well, in that case, leave it at two pounds! You're gonna send a recipe, right? (And I don't want to hear, "Cut it into 1/4" wide strips about two inches
long with a forked tail!"

| The challenge with a real-life comparison is that it would never be
possible to change only the salinity and temperature of the water.
Differences in wind and current would dwarf any tiny difference between
fresh and salt buoyancy. There's no way to duplicate wind
and current, exactly, in any two locations even pretty nearby in Puget
Sound....and there will alway be more or less wind, and typically less
current, inside the locks in the fresh water. The best test for this
difference would probably be conducted in a test tank at one of the
boat factories, but I doubt they have any provision for filling their
tanks with saltwater. |

| Maybe in a displacement boat. But I doubt the difference would be noticable
on a planing hull. "Skipper" <fairwinds@cox.net> wrote in message |

| 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. |

Derby, Kansas? |

| 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... --

Richmond. Guaranteed Virginia peanuts. You better not eat for a few days
and build up an appetite!

| 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. RCE |

| 1,500 pounds of *restuarant quality* squid???? Hmmm. I have to call you on this one Tom. You know it can only be *restaurant quality* when first frozen (after catch)
and stored at a minimum of -20F (can you store at that temperature?) for no
longer than 6 months, with documentations of the date of catch and storage.
This includes the time the restaurant stores it. Perhaps it may now be better qualified as bait? ;-) |

| What an interesting thing to theorize on! At non-planing speeds a boat MAY have a different buoyancy factor and have
an almost un-measurable difference in speed. But at planning speeds
buoyancy is not a factor. That's my opinion! Don Dando Skipper <fairwinds@cox.net> wrote in message |

| In the real world if one has to wonder about he loss of speed or extra fuel
consumption when boating in various bodies of water one either has too much
idle time on their hands or cannot afford the extra nickel/gallon in fuel
consumption for their boat. OMG. |
