The seacarts are fast, and indeed designed to be sailed on one hull. As for cost, they are way to expensive. My sailing partner, Frode, and I have a dream about a 28 foot homebuildt racing trimaran in wood. One day we will realise the dream and see what we can do compared to a Seacart or any other multi. Formula28s from the early 90s are still able to give the seacarts a run for the money in the right hands.
I dont think the M32 compares well to the Vx40. It dont have a jib and everything that implies and it dont have a similar hullshape as far as I can see. I dont see the business model behind the boat either, but hope Marstrøm do well!

What do you think about a carbon RIB.. That had me thinking "are these guys nuts??!?".
