The Blue Crab 11, also called the Gloucester 11, is an American utility dinghy that can be rowed, used as a motorboat or as a sailing dinghy. It was designed by Harry R. Sindle and first built in 1971. The design is named for the family of crustaceans.[1][2][3]
Production
The design was built by Lockley Newport Boats and Mobjack Manufacturing in the United States , but it is now out of production. Lockley Newport Boats was originally known as Newport Boats and later known as Gloucester Yachts. A total of 900 examples of then type were completed.[1][3][4]
Design
The Blue Crab 11 is a recreational sailboat, built predominantly of fiberglass. It has a fractional sloop rig, with a loose-footed mainsail and aluminum spars, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller and a retractable daggerboard. It displaces 200 lb (91 kg).[1][3]
The boat has a draft of 2.75 ft (0.84 m) with the daggerboard extended and 0.25 ft (0.076 m) with it retracted, allowing beaching or ground transportation on a trailer or car roof rack.[1]
The boat has a reinforced transom to allow the fitting of a small outboard motor.[1]
For sailing the design is equipped with transom-mount mainsheet traveler and can be sailed by one person, although a crew of two is used for racing. When sailed three people may be carried and as a motorboat it has a capacity of five people.[3]
The design has a Portsmouth Yardstick racing average handicap of 110.8.[3]
Operational history
In a 1994 review Richard Sherwood wrote, "Blue Crab is a beginner’s boat. It is dry and easily rigged, and it can be sailed by one person. For its size, it is a light boat and may be car-topped or trailered. Capacity is three adults. The transom is reinforced, so additional brackets are not required for an outboard. Blue Crab may be rowed; when not sailing, it has a capacity of five adults."[3]
