RK 20 Information, Review, Specs

The creation of the RK 20 began in 1972, with production continuing until 1981. During this period, Coastal Recreation Inc., based in Costa Mesa, California, was a notable force in the fiberglass boatbuilding industry, renowned for its "Balboa" and "Aquarius" lines. The company's manufacturing ethos focused on producing practical and accessible sailboats, contributing significantly to the democratization of sailboat ownership. The RK 20 itself is a raised deck version of the popular Balboa 20 and shares a similar hull with the Ensenada 20, demonstrating a consistent design philosophy across Coastal Recreation's offerings. Lyle C. Hess, the designer, aimed for a "slightly more speedy hull design" for this small sailboat, balancing its cruising aspirations with respectable performance for its class. Notably, the RK 20 was offered in different configurations, including the swing keel version with a maximum draft of 4.0 feet and a minimum draft of 1.75 feet, as well as a fixed keel version with a draft of 3.25 feet, displacing 2220 lbs with 820 lbs of ballast.

Sailing Performance and Handling

As a small cruiser, the RK 20 is characterized by its trailerability, allowing owners to easily transport and launch the boat for sailing in various locations. While specific performance ratios are less applicable to boats of this size, Lyle C. Hess's design intent for a "slightly more speedy hull" suggests a boat that handles capably for its class. With a displacement of 1950 lbs and a ballast of 550 lbs in the swing keel configuration, the RK 20 is designed to offer a stable and predictable sailing experience suitable for recreational cruising. Its masthead sloop rig, with a total sail area of approximately 190 square feet, provides sufficient power for light to moderate winds, ensuring an enjoyable experience for day sailing and short cruises.

Accommodations and Layout

The interior of the RK 20, consistent with its design as a compact cruiser, provides basic amenities for overnighting. While detailed interior layouts and specific headroom figures are not widely documented, its "raised deck" design likely contributes to maximizing the interior volume available for its 20-foot length. Typically, sailboats of this size and era would feature a simple open-plan cabin, likely including a V-berth forward for sleeping, some form of convertible seating in the main salon area, and possibly a small galley space suitable for basic food preparation. Storage would be modest, consisting of under-berth lockers and shelves. Ventilation would typically be provided by a forward hatch and possibly a few portlights. The emphasis of the interior is on functional use of space, providing comfortable, albeit compact, accommodations for a small crew or family.
