Gannon and Benjamin Marine Railway offers a wide range of mechanical and marine systems services.  Situated on Martha’s Vineyard, our shop and repair dock are an easy stop from anywhere in the Cape Cod area.  During the boating season we repair boats that are home-ported in our area as well as those that are cruising through and need some assistance.  Throughout the off-season we complete repairs and perform upgrades and refits on vessels that are stored in our boatyard.

Engine & Drive Train

With over 25 years of practical in-depth diesel and gasoline engine experience, we can diagnose and repair engine problems efficiently. Our shop is an authorized Beta dealer, and can service most other brands.  From tune-ups and rebuilds, through complete re-power projects, we’ll keep you running.

Mechanical and Support Systems

Electrical wiring, electronic system installation, plumbing, A/C –heating systems, generators…we’ve serviced, repaired or replaced most every system found on today’s modern yachts.  Whether repairing an existing system, or adding a new one, our work will give you years of trouble-free operation.


We are sailors ourselves and have vast experience outfitting sailboats. Whether it’s rigging, sailing system installation, boat joinery or onboard systems, we’ll make lasting repairs and upgrades that will make sailing trouble-free and enjoyable.

Whether you’re underway and need some unscheduled maintenance or would like to store with us and schedule a project for the off-season, we’d be pleased to assist you.
