Island partners changed their name to Sun Yachts in 1977.
Reinell Boat Co. in Marysville WA was the assembler.
In 1977 Bob Perry was contracted to make some revisions including elimination of the outboard well and a new raised deck and lowered house. This revised version became the SUN 27 (also known as the SUN 838).

Also available with a VW-Golf 35hp engine.
