Inflatable hull
 

This weekend I was out happily sailing until a trimaran passed me and
I went into a slump tryin to figger out a way to make a monohull do
such speeds or to make a lightweight trailer sailer that is
seaworthy. Sure, some monohulls can plane but I dont really trust
such ULDB hulls in any seas. Maybe you could incorporate some
advantages of the tri-hull into a lightweight trailerable mono in
order to enhance stability though.
Make the parts of the hull just at waterline as an inflatable
bilayer. When you start to heel, the downwind side inflates creating
much greater bouyancy on that side resisting the heel.

Dump the sailboat and buy a Bertram with twins.

Good idea. There are days when I miss our old Bert 33, right up until
I also think about the twin 454s sucking up 2 gals/mile.

You need to take a better look at boyancy. It is indeed developed and
only relational to the waterline. Once a material is "submerged" it is
irrelevant to boyancy so it does not matter if it is solid, liquid, or
gas.. although the weight may alter other calculations relating to a
hull at heel... Sorry, I am not an engineer, but hopefully you will
understand what I mean here. MA or ME feel free to chime in here, I
certainly won't be insulted.. although I may take notes..;)

A cat or trimaran will have an effective hull length longer than the same
length mono hull.
