The Surprise 15 is a development of the Skipjack 15.[1][3][4]

The design was built by Newport Boats in Newport, California, United States , starting in 1969, but it is now out of production.[1][3][5]

Design

The Surprise 15 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a plumb stem and transom, a transom-hung rudder controlled by a tiller and a retractable centerboard. It displaces 360 lb (163 kg).[1][3]

The boat has a draft of 3.83 ft (1.17 m) with the centerboard extended and 4 in (10 cm) with it retracted, allowing beaching or ground transportation on a trailer.[1][3]

For downwind sailing the design may be equipped with a spinnaker of 150 sq ft (14 m2).[1][3]

The design has a hull speed of 5.02 kn (9.30 km/h).[3]
