From oil changes to fiberglass work, our service department keeps power and sail vessels running their best on Lake Huron.

A Service Department You Can Count On

Every boat is different, and a mid sized vessel can need 150 or more service and inspection tasks each year to stay under warranty and running right. Port Sanilac Marina is here to help, whether you need routine maintenance, a repair, or simply a diagnosis. We are also a drop off and pick up site for North Sails Detroit, offering ten point sail inspections and repairs close to home.
