Design
The Gloucester 20 is a recreational keelboat, 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 stub keel with a swing keel or, optionally, a fixed fin keel. It displaces 1,650 lb (748 kg) and carries 550 lb (249 kg) of ballast.[1]
The fin keel-equipped version of the boat has a draft of 3.00 ft (0.91 m), while the swing keel-equipped version has a draft of 4.50 ft (1.37 m) with the keel extended and 1.00 ft (0.30 m) with it retracted, allowing beaching or ground transportation on a trailer.[1]
The boat is normally fitted with a small outboard motor for docking and maneuvering.[1]
The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settee berths in the main cabin. The galley is located on both sides just aft of the bow cabin and is equipped with a sink. The head is located centered under the bow cabin berth.[1]
