The Bay Hen 21 is an American trailerable sailboat that was designed by Reuben Trane as a pocket cruiser and first built in 1984.
[1][3][4] The Bay Hen 21 is a recreational sharpie, built predominantly of fiberglass, with wood trim.
[1][3] The boat has a draft of 3.50 ft (1.07 m) with a centerboard extended and 9 in (23 cm) with both retracted, allowing beaching or ground transportation on a trailer.
[1][3] The boat is normally fitted with a small 2 to 5 hp (1 to 4 kW) outboard motor, mounted in a stern well, which is forward of the rudder, for docking and maneuvering.
[1][3] The design has sleeping accommodation for two people, with a double berth in the cabin, that can be folded into a settee.
