1979 Mainship 34 Sedan

This 1979 Mainship 34 Sedan is a fiberglass trawler powered by a single 158-horsepower John Deere diesel engine. The 34-foot hull with 12-foot beam is a proven cruising platform suited to extended passagemaking and anchoring out.

Recent work completed in 2025 includes bottom paint and zincs, new stainless steel engine stringer brackets, rebuilt engine mounts, engine and propeller shaft realignment, renovated transmission slide brackets, and a new through-hull fitting for engine seawater cooling. These updates address core systems and structural support for the powerplant.

The boat is in good condition overall. The trawler sedan layout provides comfortable accommodations for cruising with protected pilothouse steering and living spaces arranged for extended time aboard.
