The first in a series of 31-foot Sundancer models Sea Ray has built over the years, the 310 Sundancer is a wide-beam family cruiser with a roomy mid-cabin interior and a very spacious cockpit. Notably, she was one of the larger boats in the Sea Ray fleet during her production years. Built on a solid fiberglass hull, the interior of the 310 was among the largest to be found in a boat this size during the early 1980s. Originally arranged with a bulkhead separating the forward stateroom from the salon, the interior was completely revised in 1983 when Sea Ray eliminated the cabin bulkhead and introduced a more open (and even more spacious) layout. There are sleeping accommodations for six with either configuration—four adults and two kids—along with an enclosed, standup head and a full galley. The cockpit seating is a little unusual: a double-wide passenger seat with fold-down aft-facing jump seats resides in the center of the cockpit, just behind the helm. Note the absence of a transom door. Among several engine choices, twin 350hp gas inboards cruise the Sea Ray 310 Sundancer around 20 knots with a top speed in the neighborhood of 30 knots.
