Default Getting a pontoon boat to plane

A friend of mine built a custom pontoon boat roughly 34' long with
beautiful woodwork. It is powered with a 90 hp and he claims he had
the prop pitched by an expert. He attains 18 mph so he is planing
some but gets very bad fuel economy, I'd estimate 1 mpg. Underway,
most people sit on the foredeck so she probably is bow heavy. Is
there some way to get her to plane better? He does have one of those
Dol-Fin things on the motor but I think he needs more planing surface
along the pontoons.
