Sorry to contribute to this "doomed" thread
but I will side-step the direct question of mono vs multi, except to make these points: The way to open anyone's mind is through experience and knowledge. They both have pros and cons, and every boat design involves trade-offs and compromise.
A much higher percentage of multihull
owners have had extensive monohull ownership
experience than the other way around.
Instead I'll focus on the "flippable" question and state my view that probably 98+% of the cases of multihull capsize
are a direct result of operator error carrying too much sail for conditions; not any different than driving a car too fast around a sharp bend. Monohull capsize
is more likely as the direct result of being rolled by waves, but they are more forgiving of operator error related to steering
and sail handling in overpowering winds.
I've never seen any statistics, but judging by experience and reading believe multihull capsize probably happens most often to racers who are deliberately pushing their boats to the edge. Most often it is when sailing downwind -- when a sudden slowing of the boat (whether by accidental round-up from unbalanced sail configuration or helm
error, burying the bow or other accident) causes a sudden rise in apparent wind
. Second most frequent is failure to reef or lower sails
at the onset of a strong squall or weather
front, and third is carrying too much sail in gusty conditions and failing to "reef for the gusts".
See my first post on this forum, which was how to avoid these errors. Multihull Capsize Due to Lack of Experience
