The S2 5.5, also called the Grand Slam 5.5, is an American sailing dinghy that was designed by Don Wennersten as a racer and day sailer and first built in 1982. The designation indicates the approximate length overall in meters.[1] [2]
The design was the smallest boat S2 Yachts produced and its only dingy model.[3] [4]
The design was built by S2 Yachts in Holland, Michigan, United States from 1982 until 1983, with 70 boats completed, but it is now out of production.[1] [2] [3] [4]
The S2 5.5 is a recreational sailboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a retractable centerboard. It displaces 6000NaN0 and has a small cuddy cabin for stowage.[1] [2]
The boat has a draft of 4feet with the centerboard extended. With it retracted the boat can operate in shallow water, be beached or ground transported on a trailer.[1] [2]
The design has a hull speed of 5.4kn.[2]
