1978 Mainship 34 Trawler - Addi Leigh

Classic Mainship Project | Perkins Diesel | Restoration Opportunity

Addi Leigh is a 1978 Mainship 34 Trawler being offered as a significant project boat for the right buyer. This is not a turnkey vessel and should not be approached as one. She needs substantial restoration, cosmetic work, cleanup, systems review, and overall investment before being considered ready for comfortable cruising.

That said, the Mainship 34 remains a respected classic trawler design with a strong following for good reason. These boats are known for their practical layout, economical cruising profile, manageable size, and comfortable liveaboard-style accommodations. For a buyer with the skills, time, and vision to restore an older boat - or the budget to hire out the work - Addi Leigh represents an opportunity to bring a proven trawler design back to life.

She is powered by a Perkins diesel engine, a well-regarded and widely supported powerplant commonly appreciated for longevity and fuel efficiency. The boat also includes installed heating and air conditioning systems, along with a functional cruising-style layout featuring a galley, salon space, and sleeping accommodations.

The interior and exterior both show clear signs of age and deferred maintenance. Buyers should expect this vessel to require a serious hands-on approach. This is best suited for someone who understands older boats, is comfortable evaluating repairs, and sees value in starting with a known classic hull and rebuilding from there.

Notable features include:

• Classic Mainship 34 trawler design
• Perkins diesel engine
• Economical displacement-style cruising platform
• Spacious layout for a 34-foot vessel
• Galley with microwave, refrigerator, and cooktop
• Heating and air conditioning installed
• Sleeping accommodations for up to three
• Good candidate for restoration, refit, or liveaboard conversion
• Strong potential for a skilled owner or investor-minded buyer

Addi Leigh is being sold as a project vessel with significant restoration needs. She is not for the casual buyer looking for immediate use, but for the right person, she offers a solid starting point in a classic trawler model with lasting appeal.
