Just picked up a 20' Baker tunnel hull with a 200HP Mariner. It ran great.
I imagine when I get used to setting the jack plate just right and trimming
the engine perfect I'll probably be able to run close to 80 with it. Maybe
a little quicker with a different prop.

Anyway, I noticed something intersiting. Going away from the wind it ran
flat and quick, but running into the wind it tended to porpoise a little. I
had to trim it down a little to prevent that. Now for the question. Do
tunnel hulls trap air and porpoise?

I noticed it didn't seem to do it as much at higher speeds either.
