Finally, a pontoon boat with equal parts performance and comfort. The Grand Mariner CW 250 Twin Engine provides both in excess. With the CW floorplan, you’ll enjoy two plush bow lounges, an UltraLux high-back reclining helm seat and two rear chaise lounges with swim deck seating. A 12-foot Bimini top, soft-sided cooler, swim deck with four-step boarding ladder and six-speaker Polk® stereo add to the creature comforts. Great lengths have been taken to ensure the safety and stable performance of the Grand Mariner CW 250 Twin Engine, such as three 27-inch diameter reinforced pontoon tubes using 0.125-gauge aluminum and a 93-gallon forward-mounted fuel tank to minimize bow rise.
