Re: tri hulls
Trihulls do tend to pound when head-on into waves but there are ways to lessen that effect. I operate mine in Lake Ponchartrain, in the New Orleans area, often. This is a very large but shallow lake, and can "kick up" very quickly.
What I do when we get the large, closely spaced waves that are common to such lakes, is to run with the bow quartering the waves - I don't try to tun directly into the seas, even if my destination is in that direction. I also back off the power until the boat is right at the point of planing, which tends to push the bow up quite a bit. This is not a particularly fuel efficient profile but it keeps the boat relatively dry.
On the postive site, trihulls tend to be pretty roomy and they are very stable at rest. I use mine mostly for photography and it is a great platform for that purpose. Mine is underpowered by most people's standards but it will cruise in the low to mid twenties with good fuel economy for a boat - I get about 4mpg in that mode.
