Put together an expert design, impeccable detailing, engaging layout, appreciated amenities and reliable performance, and you have the Grand Mariner SL 250. This luxury pontoon boat provides the cruising and water-sports capabilities of the Grand Mariner 250 and SEL 250 while enhancing the opportunities for truly personalized living space. With the SL floor plan, you'll enjoy two plush bow lounges, a comfortable amidships lounge, an UltraLux high-back reclining helm seat and a single rear-facing lounger with flip-top backrest. The DL floor plan provides two elegant rear-facing lounges instead, with under-seat storage. You can also replace the portside bow lounge with two UltraLux seats and a flip-up table. 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, as does the available SmartCraft™ gauge, Glass Dash Helm, stainless-steel grill, entertainment center with refrigerator and even an entertainment galley with bar stools, sink and wine cellar. Then there are the performance and lighting options, water-sports and fish features, stereo and speaker upgrades and so much more. With the Grand Mariner, pontooning itself becomes a grand adventure.
