Repowered with a reliable Cummins 5.9L diesel and boasting fresh flybridge upholstery and 2021 camper canvas, this classic Mainship 34 is a well-kept example of a fuel-efficient coastal cruiser ready for your next adventure.

Originally marketed as an affordable, fuel-efficient alternative to the larger twin-engine yachts of the 70s, the Mainship 34 quickly built a reputation for its reliability and practicality — over 1,200 hulls were produced, many of which are still cruising today.

This 1977 Mainship 34 stands out as a solidly built cruiser with practical upgrades. Repowered with a Cummins 5.9L diesel, it delivers improved reliability and efficiency over the original configuration. The flybridge boasts fresh upholstery and a full camper canvas enclosure (2021), creating a comfortable helm in all weather.

The layout remains true to its original design — straightforward and functional, with clean lines and a warm, classic interior. Notable onboard features include dual 100-gallon fuel tanks, oversized 30kg Lewmar claw anchor, and a retrofit transom door — all ideal for longer trips, peace of mind at anchor, and stress free docking

Electronics are simple and user-friendly, with a Standard Horizon chartplotter supported by iPad Navionics for redundancy. At the stern, a heavy-duty aluminum swim platform adds lasting durability and utility — perfect for gear handling, boarding, or dockside work.

Overall, this Mainship 34 is a capable cruiser with the right mechanical updates, ready to take on the next chapter with confidence.
