Manufacturer Info



This company made its mark back in 1977, when an international fuel crisis paved the way for the boating public to embrace a new, single-diesel cruising boat that the average family could afford. That boat was a Mainship and 1,200 hulls were subsequently built. Since that time, Mainship has been known as a leading manufacturer of production trawlers. The company was recently acquired by Marlow-Hunter , and the brand continues to embrace its value position although without sacrificing quality or comfort. Mainship cruisers ride on hulls that offer fuel efficiency at displacement speeds, but they’re designed for planing speeds, too. A popular boat among liveaboards, amenities include full-service galleys and roomy cabins. For safety, there are wide and deep flybridge steps, raised bulwarks, deep cockpits and oversized stainless rails on deck.

Additional Information

Mainship 40 DC was notable in the late 1980s for her distinctive, trawler-style profile. This is a very practical boat, long on useful features.

Her traditional Downeast profile,her performance and interior accommodations are similar to those of a modern motor yacht.

The salon dimensions for a 40-footer with plenty of room to entertain guests in comfort. A lower helm, port and starboard salon deck doors, and a built-in bar were standard.

The full-width aft stateroom includes a double berth, excellent storage, and a tub/shower in the adjoining head compartment. (In 1985, light oak woodwork replaced the original dark teak interior joinery.)

Topside, the aft deck is large enough for casual entertaining.  

Additional features include a bow pulpit, wide side decks, fold-down radarmast, and a swim platform with ladder.

The Mainship 40 DC will cruise at a espectable 18 knots with standard 350hp Crusader gas engines and reach a top speed of around 25 knots
