Coupling a compact 15-foot frame with a razor-tight helm, the 150 Speedster pulls off twists and turns that would leave a gymnast tied in knots. Add in a 155 horsepower Rotax® 4-TEC® engine or a 215 horsepower or 255 horsepower supercharged, intercooled and you arrive at a boating experience somewhere north of exhilaration. And way off the map for any other boat.
