Twin Vee (Jabba Jaw)
22-ft Twin Vee This boat has a carrying capacity of up to 1500 pounds and up to 7 people and a shallow draft (9 inches empty). This boat's cat hull design results in a smoother ride in choppy water, at the expense of a slightly deeper draft. This boat is powered by two Yamaha 70hp motors.
