Bay Harbor Marina

Since 1969, Bay Harbor Marina has served boating enthusiasts from a strategic location near the mouth of the Saginaw River in Bay City, Michigan. The full-service facility operates 408 slips accommodating vessels up to 60 feet, with side ties extending to 90 feet, alongside nearly 200,000 square feet of year-round boat storage. As a member of the TopSide Marinas family, the marina combines decades of local expertise with the backing of a respected network of Great Lakes marine facilities serving Bay County and surrounding communities including Essexville and Linwood.

The marina's position provides immediate access to Saginaw Bay and Lake Huron, making it an ideal home port for both day cruises and extended Great Lakes voyages. Boaters launching from Bay Harbor Marina can reach open water quickly, with floating docks featuring wide piers and generous fairways that simplify boarding and docking even in challenging weather conditions. The protected harbor has earned a reputation for being weather-safe while maintaining easy access to some of Michigan's finest cruising grounds.

Bay Harbor Marina's service yard handles vessels ranging from 18 to 90 feet, staffed by factory-trained and certified technicians specializing in comprehensive marine repair and maintenance. The team holds authorized service credentials for major brands including Garmin, Mercury Marine, Raymarine, Volvo Penta, Yanmar, Seakeeper, and Yamaha. Services span the full spectrum of marine needs: engine repair and diagnostics, marine electrical work, electronics installation, fiberglass repair, gelcoat restoration, bottom painting and antifouling, carpentry, canvas work, and rigging. This breadth of capability allows boat owners throughout the Bay City area to address nearly any maintenance or refit requirement without leaving the facility.

Winter storage options accommodate Michigan's demanding off-season climate with heated indoor storage for vessels requiring climate-controlled protection, plus cold storage and outdoor alternatives for budget-conscious boaters. Professional shrink wrap services complement all storage tiers, and the marina encourages early reservations as capacity fills quickly each fall. Many owners schedule fiberglass work, engine maintenance, and painting during winter months to avoid spring bottlenecks and ensure readiness for launch season.

Beyond slips and service bays, the facility functions as a complete boating hub. The fuel dock supplies ethanol-free gasoline and diesel seven days weekly, while the ship store stocks maintenance products, boating gear, provisions, and beverages. Two full bathhouses, pump-out services, and a heated pool with sundeck round out the amenities. Seven-day in-and-out service provides maximum flexibility for owners keeping boats in storage who want quick launch access with a simple phone call.

Bay Harbor Marina's combination of protected deep-water access, comprehensive repair capabilities, and extensive storage infrastructure positions the business as one of the Saginaw Bay region's most complete marine service destinations for sailors and powerboaters alike.
