Design
The Sonata 8 is built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a transom-hung rudder and a lifting or optionally fixed fin keel. It displaces 2,822 lb (1,280 kg) and carries 500 lb (227 kg) of ballast.[1][4]
The boat has a draft of 5.09 ft (1.55 m) with the keel down and 0.69 ft (0.21 m) with the keel retracted. The fixed keel version has a draft of 5.2 ft (1.6 m).[1][4]
The design has a hull speed of 5.96 kn (11.04 km/h).[4]
