What are you looking to do with a trimaran
or any multihull for that matter?
It's possible to capsize
any multi if you push it hard enough.
That being said, I've never come close with my Dragonfly 1000.
Several years ago, during a trimaran delivery
from Puget Sound
to Southern California
, three of us sailors with variable experience came close to a capsize
off Cape Mendocino. It was due to several conditions, partly boat outfitting design (jam cleat location and orientation), boat condition (centerboard stuck down), weather
(slowly increasing wind
with lots of sun), crew interaction(newb insisting on going DDW to avoid any semblance of roll in swells), and lastly, crew fatigue.
leaned back in the cockpit
which released the barberhaul on the jib
. (BAD PLACEMENT BY THE MANUFACTURER)
immediately gybed which put us from DDW to a close reach.
We almost capsized before recapturing control.
was stuck down before the trip started (my bad for not insisting it was fixed before the trip started) which exacerbated the condition.
was such that we couldn't turn downwind for over a mile.
We were doing better than ten knots on a close reach with flogging sails
with the tiller hard over. The boat was heeling around 30 degrees with the windward tramp blown upward like a balloon.
It can happen regardless of boat size.
