That racing trimaran
that recently capsized is a prime reason that I'd never single
hand a multi across the ocean. If there is no one at the helm
to react to a sudden gust of wind
, it is too easy to expose the dark side of a multi. Looked like the tri was running on auto pilot handily under control with both crew on the windward ama or trampoline. When the gust hit, they couldn't dump the main sheet or head
off the wind
. Result was an excruciatingly slow roll up to the point of no return.
From memory, it looked like the tri heeled so it's rudder
was out of the water
. That precluded steering
the boat out of trouble. With no steering
input, the boat just sat there and slowly continued heeling till it went beyond the point it could recover. Dumping the main might have saved them but neither crew was in a position to do that. A catamaran would have kept one rudder
in the water
but may have been quicker to roll to a point where it couldn't recover. In any case, without someone on the helm
to make split second heading and sail condition changes, they are too prone to prone to floating upside down.
As I've said before, it's little consolation that the boat will float upside down if you drown because you get tangled in rigging
or knocked unconscious as the boat goes over. That happened to an acquaintance on a tri. Found the boat turned turtle with the crew drowned and him missing.
