Few segments of the American boating industry are as competitive as the market for midsize, 30-something express cruisers. This is the sweet spot for many boaters, the intersection of size and value where several manufacturers slug it out for valuable market share. The Sea Ray 310 Sundancer—latest in a series of 310 Sundancer models reaching back to 1990—combines leading-edge styling with the luxury one expects in a modern Sea Ray yacht. Like most of her Sundancer siblings, the 310 rides on a deep-V hull with moderate beam, cored hullsides, and a solid fiberglass bottom. Below decks, the mid-cabin accommodations are a rich blend of satin-finished cherry cabinets, hardwood flooring, leather upholstery, and designer galley appliances. Privacy curtains separate the sleeping areas from the main salon, and a 19" flat-screen TV can be viewed from anywhere in the cabin. Note that the 310 Sundancer’s modest 10-foot beam—slender compared with many express cruisers her size—dramatically improves handling, performance, and fuel-efficiency. Cruise at 25 knots (high 30s top) with 260hp Mercury Bravo III drives. Axius drives with joystick controls are optional.
