Premier is one of the most innovative toon makers and with the 290 Grand Isle SL with the optional 10' (3.04 m) beam she could hold a small orchestra. This triple-toon has a rated capacity of 18 people, so that is a good start. Her outside tube diameter is 25" and in the PTX high-performance version her center toon is 36" and has a pad. With enough outboard power strapped to her stern she can also scoot.
