Re: What is the best pontoon for pulling a wakeboard?
First, ya need to find out what the gate dimensions are; then ya can determine if your wheel chair will "get in." Is front or side entry preferred? Then ya can whittle down the choices.
Most pontoons have an option for a "ski tower", but ya really, really need to get the dealer to commit if it will stand the stress. Believe it or not some are mainly for show as they easily pull out. See how it is attached to the deck.
As others have stated, you won't necessarily get the wake-board wake from a pontoon, but most should be able to pull one.
Most tubes are round, some are U-shaped, and one is hexagonal. Not sure if shape will affect the wake that much between them.
