In browsing through the Canadian Transportation Board's marine accident
reports, you frequently come across laments that the (often deceased)
fishers and sailors failed to appreciate just how destabilizing the "free
surface effect" of water can be. (I'm no techie, but as far as I can tell
"free surface effect" is tech-talk for "sloshing".) I do remember that
water weighs about
64 lbs. per cubic foot, depending on whether it's fresh or salt. Here on
the Wet Coast, it's not uncommon to have to pump out your boat in the
morning if you've left it out on the beach without the cockpit cover. I'm
quite prepared to believe the weight and momentum of a few inches of water
in the boat could damage the boat, cause it to shear through roof rack
lines, and/or
tip the car itself under the wrong acceleration/de acelleration/turning
circumstances. And I suspect that if it did so, you could be charged with
carrying an "unsafe load" in the same way truckers are liable if stuff
blows or shears off their trucks. Most of us have a cockpit cover anyway
and it doesn't seem like a great burden to use it when you consider the
potential damage to the boat, ourselves and others.
