I am a first-time boater considering purchasing a deck boat for weekend lake cruising. Have looked at the 220 and 240 Sundecks. The dealer is pushing the 240 on the basis of more room, a smoother ride, and relatively little spread in the cost (several thousand dollars with the Bravo III upgrade on the 260 HP engine). At the same time, most often there will be only two people going out on the boat and I don't wan to buy more boat than we need. Any advice?
