Why Marina Valuation Matters
Whether you're buying your first marina or selling a family-owned operation, getting the valuation right is the single most important step. Unlike traditional commercial real estate, marinas have unique variables — slip counts, water depth, fuel operations, dry storage capacity, and storm exposure — that make appraisals more art than science.
At Marina Deal Flow, we track every marina transaction in the United States. Here's what the data tells us about how marinas are actually valued in 2026.
The Three Approaches to Marina Valuation
1. Income Approach (Cap Rate)
The income approach is the most common method used by institutional buyers. It works like this:
Marina Value = Net Operating Income (NOI) / Capitalization Rate
Cap rates for marinas in 2025-2026 typically range from 6% to 10%, depending on location, condition, and tenant quality. Stabilized, well-located marinas in Florida or the Northeast command cap rates as low as 6-7%, while value-add or secondary-market properties may trade at 8-10%.
For example, a marina generating $1.2M in NOI at an 8% cap rate would be valued at $15M. That same NOI at a 6.5% cap rate — typical for a coastal Florida property with long waitlists — would be worth $18.5M.

2. Comparable Sales (Price Per Slip)
Price per slip is the marina industry's version of "price per square foot." It's the quickest way to benchmark a deal and the metric that shows up in nearly every broker pitch deck.
Based on our transaction database of 50+ deals, here's what we're seeing:
- $10K–$30K/slip: Distressed, rural, or freshwater marinas needing capex
- $30K–$80K/slip: Mid-market marinas in decent locations with stable revenue
- $80K–$150K/slip: Well-located coastal marinas with waitlists, fuel, and ancillary revenue
- $150K–$463K/slip: Ultra-premium — think South Florida, San Diego, or Boston Harbor
The wide range reflects the reality that not all slips are created equal. A 60-foot slip in Fort Lauderdale generating $3,000/month in rent is fundamentally different from a 25-foot freshwater slip in rural Kentucky at $200/month.
3. Replacement Cost
With permitting timelines stretching to 5-10 years and construction costs surging, replacement cost has become an increasingly important floor for marina valuations. Building a new marina from scratch — if you can even get the permits — costs $50K-$150K per slip in most coastal markets, before land.
This is why even distressed marinas in good locations trade at premiums: the entitlements alone are worth millions.
What Drives Premium Valuations
The highest-value marinas we track on our acquirer leaderboard tend to share these characteristics:
- Location: Coastal, deep water, proximity to affluent boating populations
- Waitlists: Slip demand exceeding supply is the strongest indicator of pricing power
- Ancillary revenue: Fuel, boat storage, repair services, restaurants, and retail
- Upland development potential: Waterfront land with mixed-use zoning
- Protected harbor: Natural or man-made storm protection
Red Flags in Marina Valuations
- Deferred maintenance on docks, seawalls, or pilings (can run $5K-$15K per slip to rebuild)
- Environmental liabilities from fuel operations or legacy contamination
- Lease vs. fee simple — many marinas operate on ground leases with limited remaining terms
- Below-market rents that inflate occupancy but mask true demand
