The Mobjack is an American sailboat that was designed by Roger Moorman as a one design racer and first built in 1956.[1]
The boat is named for Mobjack Bay, Virginia.[2]
Production
The design was built by Mobjack Manufacturing in Gloucester, Virginia and Newport Boats in Newport, California, United States , among other builders. Production started in 1956 and ended in 2003 with 537 boats completed, but it is now out of production.[1][3][4]
Design
The Mobjack is a recreational sailing dinghy, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a plumb stem and transom, a transom-hung rudder controlled by a tiller and a folding centerboard. It displaces 450 lb (204 kg).[1]
The boat has a draft of 4.00 ft (1.22 m) with the centerboard extended and 9 in (23 cm) with it retracted, allowing beaching or ground transportation on a trailer.[1]
For sailing the design may be equipped with a spinnaker of 240 sq ft (22 m2). A single trapeze is normally used by the crew.[1]
Operational history
The boat is supported by an active class club that organizes racing events, the International Mobjack Association.[1][5]
