Notes

Optional shoal draft keel: 3.75 ft
The original boat, called a Cheetah 26, was designed by Edwin Monk Jr. Bob Perry was contracted to make some revisions including elimination of an outboard well and a new raised deck and lowered house. This revised version became the SUN 27 (also known as the SUN 838).
Sun Yachts/Reinell Boat Co. continued to build the Sun 27 until 1980 when Reinell closed its doors. At that point, the molds were sold to Specialty Yachts who, in turn, commissioned Spencer Boats Ltd to build the what would then be called the SUNSTAR 28.
