Tower Marine

What Tower Marine does

Tower Marine, operating as Safe Harbor Tower Marine, is a full-service marina located on the southern shore of Lake Kalamazoo in Douglas, Michigan. Founded in 1964 and now operating under the Safe Harbor marina network, the facility serves boat owners and waterfront lifestyle consumers with a comprehensive portfolio of moorage, storage, repair, and ancillary services.

The marina's core product suite spans four storage lines — wet slips (25'–116'), transient slips (16'–100'), outdoor dry storage (50'–60'), and winter storage (indoor, indoor heated, and outdoor for vessels up to 50') — supported by a certified vessel service center with 16+ repair capabilities including canvas, electrical, engine, electronics, fiberglass, hydraulics, rigging, paintwork, refrigeration, and winterization. The facility is equipped with 60-ton hoists, hydraulic trailers, and a self-service yard, and holds ABYC certification along with authorized dealer status for Mercury, Yamaha, North Sails, Seakeeper, and Seakeeper Ride. Ancillary amenities include the seasonal Red Dock Café, a ship's store, a swimming pool, complimentary Wi-Fi and shore power, and a monitored RV storage facility accommodating units up to 65'.

The business model is a hybrid of recurring subscription revenue (wet slip memberships, dry storage, winter storage, RV storage), short-stay transient rentals (booked via Dockwa), professional service revenue (vessel repair with labor and parts markup), and transaction-based revenue from the on-site restaurant and ship's store. Pricing is quote-based rather than published, reflecting a direct-to-consumer GTM focused on local and regional boat owners, supplemented by Safe Harbor's national membership network for cross-location acquisition. The customer base is fragmented across individual boat owners, transient travelers, and RV owners, with no enterprise concentration.
