Mainship 40 Power Yachts For Sale

The Mainship 40 Double Cabin is presented in listings as a trawler-styled motor yacht with a recognizable, trawler-style profile and a 40-foot overall length. The design emphasis in advertised examples centers on interior volume and a layout intended for comfortable liveaboard or cruising use, with a large, open salon that provides space for socializing and underway or at-anchor entertaining.

Produced in the early 1980s, the listing for a 1984 Mainship 40 Double Cabin (named Phase II) shows a two-stateroom, two-head arrangement. The master stateroom head is described with a tub/shower combination, while the guest stateroom head features an enclosed shower. This double-cabin configuration separates sleeping areas and provides two private heads, a layout that supports multi-person cruising and overnight guest accommodations without relying on salon conversions.

Practical experience with at least one hull is documented: Phase II is a two-time Great Loop veteran and her owners continue to cruise her. That operational history demonstrates that at least some Mainship 40 Double Cabin examples have been used for extended, continuous cruising and liveaboard passages, and that the layout and systems on those examples were maintained at a level sufficient for long-range cruising itineraries.

The combination of a roomy salon and two-cabin, two-head accommodations makes the Mainship 40 Double Cabin notable for owners who prioritize interior comfort and guest privacy over minimalist or purely passage-oriented arrangements. The listings emphasize interior accommodation and cruising provenance rather than propulsion, performance numbers, or construction details, so prospective buyers should refer to specific vessel documentation for systems, machinery, and structural particulars.

Information in the available listings concentrates on layout and operational history rather than builder options or equipment lists. For valuation, survey, or refit planning, the documented Great Loop passages and continuing use by current sellers provide relevant context about how at least one Mainship 40 Double Cabin has been employed in practical cruising scenarios.
