From first-had experience, I would advise all you off-shore racers to not only paint your hull to look like an obese, clumsy, Japanese-speaking Orca - but to also post a chump in the cockpit to read "Latitude 38" missives very loudly through your kickin' transducers. That bores the hell out of any self-respecting sea creature.
We did all this during the infamously nocuous "HoHo-HumHum" race off of Madagascar in '87 and it saved our hides.
Here's what happened to the poor boat next to us who had not prepared as we had (notice that they were playing classical music in the background...to no avail):
It's clear by the video that it was an evil Baluga that sucked 'em under.
