I would have thought that a Camel boat with light coloured tubes so they don't get to hot and a frame which would support a cover to keep the sun off the american tourists, lots of seats, a reliable Honda engine, again not to fast to scare the folks would be ideal.
But if you want to go faster then stick an Optimax on the back end
a 225 should give it something to scare people with. The hull is deep V so for its size it will handle short steep waves, the alternative would be to go up in size to 8m perhaps.
