1981 SISU Downeast

This 26-foot SISU Downeast is a fiberglass-hulled cruiser built for serious fishing and coastal exploration. The boat is powered by a single 120-horsepower Perkins diesel engine, delivering a cruising speed of 9 knots with a top speed of 12 knots—efficient performance suited to extended offshore work.

The diesel powerplant has undergone major mechanical updates, supporting reliable long-range operation. The hull design and modest beam of 8 feet reflect the classic Downeast profile, built to handle rough water while maintaining reasonable fuel economy for extended cruising.

This is a working boat, built without unnecessary frills and designed to earn its keep whether deployed for fishing or extended coastal voyages.
