The RK 20 is an American trailerable sailboat that was designed by Lyle C. Hess as a cruiser and first built in 1972.[1] [2] [3]
The RK 20 is a development of the Hess-designed Balboa 20, as is the Ensenada 20.[1] [3] [4] [5]
The design was built by RK Industries, a subsidiary of Coastal Recreation, in the United States. It was built between 1972 and 1981, but it is now out of production.[1] [3] [6]
The RK 20 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig; a spooned, raked stem; an angled transom; a transom-hung rudder controlled by a tiller and a swing keel or fixed fin keel. The swing keel version displaces 19500NaN0 and carries 5500NaN0 of ballast, while the fin keel version displaces 22200NaN0 and carries 8200NaN0 of ballast.[1] [3]
Two cabin designs were available, a trunk cabin and a raised deck version.[3]
The fin keel-equipped version of the boat has a draft of 3.25feet, while the swing keel-equipped version has a draft of 4feet with the keel extended and 1.75feet with it retracted, allowing operation in shallow water, or ground transportation on a trailer.[1] [3]
The boat is normally fitted with a small 3to outboard motor for docking and maneuvering.[1] [3]
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. Cabin headroom is 450NaN0. The fresh water tank has a capacity of .[1] [3]
The design has a PHRF racing average handicap of 264 and a hull speed of 5.6kn.[3]
In a 2010 review Steve Henkel noted, "the RK20 fixed-keel version would seem preferable, since it eliminates the mechanical problems some owners have experienced with the swing keel."[3]
