Re: T&T: Airing up the dink - hard-sided dink adherents may
"Raising the dink (even a light weight one) that is on top, will adversely
affect the boats center of gravity. Hope you have fin stabilizers other wise
you are going to roll more then you did."
Boats, I assume this is a joke right?
My dink with motor weighs right at 180 pounds and is still below the level
of the flying bridge. I weigh more than that. Do I need to activate my
non-existent stabilizers every time I go the FB? Or, I could counteract the
metacentric height change by staying at the lower station in heavy weather.
:)
Being an ex-salvage ship skipper, I have the information at hand to do the
change of metacentric height calcs, but some weight moves are too trivial,
especially 180 pounds at 22 inches on a 40,000-pound boat.

Actually having the dinghy on top is an asset:
- The weight of the dinghy will cause your vessel to ride lower in the
water reducing the slap on the hard chines when waves are not directly from
the bow. - The viscosity of the water will tend to grab the hull since it is now
deeper in the water and keep it from rolling as much as an empty vessel. - The dinghy is ready and more available on top in case of your vessel
sinking. - We carried our 10' Avon Rover with 8HP engine on the top of our Grand
Banks 32 for most of the 7350 miles on the loop with no noticeable effect. - Just kidding on all but #4.

Here is some copy from a press release just issued, the first documented
9-1-1 incident for SPOT.
ALASKAN REMOTE LONE-WORKER SAVED BY 9-1-1 MESSAGE FROM GPS SATELLITE

MILPITAS, CA. - (January 9, 2008) - Mike Brady, an outdoorsman working
alone maintaining a seasonal lodge over winter, was rescued after using

location in a remote section of Alaska.

Click on the SPOT (left column) -- looks interesting to me, and possible
others as an alternative to high cost satellite telephone service.
Hey, Vance. I have to also be careful when returning to the mother ship in
the dink if there is a really low tide because the boarding ladder will be
too far above the water for me to reach. :)
