More Than Marine Service

Full Service Custom-Designed Welding, Fabrication, Repair & Machinery

A full service marine, welding and fabrication shop conveniently located in Port Dover. By water, just past the lift-bridge, look for the big yellow shop on the east side of the river. Or by land, at 35 River Dr. Port Dover ON N0A 1N7.

Family owned and operated since 1976, Tiller Marine, formerly Jack Matthews Marine Service Ltd., has been servicing and fabricating tug boats and steel craft for years. Originally a general marine and engine repair service with a passion for tugboats, over time, and with a new name and a dedicated mascot, Tiller, we have evolved into an impressive welding and fabricating shop that offers a variety of services to a more diverse client base. We're known for our custom-designed welding, machinery and parts. If you have an idea; we’ll design and build it. We also offer long standing contacts with some hard to find suppliers in the marine industry.
