1978 Mainship 34 – Extensively Rebuilt Cruiser With CUMMINS DIESEL AND BOW THRUSTER-Great Price For This One!
Classic Mainship style with major upgrades where it counts. This 1978 Mainship 34 has been extensively rebuilt over the past five years, making it a solid option for cruising, weekend trips, or extended time on the water.
Powered by a 1988 Cummins diesel that has been completely rebuilt with only 15 hours, this Mainship offers dependable diesel performance in a classic trawler-style package. A bow thruster adds confidence around the dock, while the brand-new canvas with Isinglass enclosure and custom camper back expand the usable space and make the boat more comfortable in changing weather.
This boat is also well set up for cruising, with twin 110-gallon fuel tanks, 40 gallons of fresh water, and a 25-gallon holding tank. Recent comfort and utility features include a new head with Smart Flush control, inverter, FloScan fuel monitoring system, and transom sunscreen.
A 2018 Inmar 9’ dinghy with 6 hp outboard and davits is included, making it even easier to anchor out, explore, or get ashore.
