Re: Will trim tabs work well with a trihull?
I don't think the hull design makes much difference, although with a tri-hull you won't be trimming the bow down to deal with chop like you would a deep v.
I love my trim tabs on my 21' but i don't think they are worth the money for a small boat (14-16). You can always trim with the motor, or weight, for bow/stern and by shifting weight port/starboard.
