Marina

Boat slips behave a lot like waterfront self-storage

Marinas rent boat slips, dry storage, winterization services, fuel, repairs, and convenience items to boat owners. The surprising angle is how sticky slip revenue can be in constrained waterfront markets: once a customer has a desirable slip and nearby storage, they often stay for years and buy multiple ancillary services from the same operator.

How It Works

Revenue starts with seasonal or annual slip rentals, then expands through dry storage, haul-outs, winterization, repairs, fuel docks, retail, and boat club memberships. Good marinas optimize occupancy, waitlists, service revenue per boat, and waterfront real estate use. Scarce permits and waterfront access create moats that are hard to duplicate.

Source: SBA 7(a) FOIA dataset, filtered to acquisitions (loans where business age is "Change of Ownership"). Implied deal size assumes an 85% loan-to-purchase ratio, a common SBA change-of-ownership structure. Charge-off rate shown only when 10+ loans have resolved (paid in full or charged off). Interest rates reflect last 24 months only. Actual deal values vary with equity injections, seller financing, and working capital terms.

Pros

  • +Scarce waterfront supply creates real pricing power in strong markets
  • +Multiple ancillary revenue streams per customer
  • +Customers can stay for years once they secure a good slip
  • +Real estate and operating business upside in one asset

Cons

  • -Extremely capital intensive to acquire or develop
  • -Weather, seasonality, and storm exposure affect results
  • -Environmental compliance and insurance can be painful

Best For

Investors who want an asset-heavy business with real estate scarcity, ancillary services, and long-duration customer relationships

Operating Costs

Major costs include dock maintenance, dredging, fuel systems, payroll, insurance, utilities, environmental compliance, and debt service. Margins improve with high occupancy, waitlists, service work, and dry storage expansion.
