Florida leads the nation in registered boats while enclosed dry-stack and RV storage supply lags badly behind. The statistics behind the demand, how Wert-Berater builds a lender-grade feasibility study for inland marine and RV/boat storage — and the risk register underwriting actually tests.
Bottom line: Florida’s boat and RV storage market is one of the clearest supply-demand imbalances in commercial real estate today. The state leads the nation in registered recreational vessels, waterfront marina capacity is structurally shrinking, post-hurricane insurance economics punish waterfront operators, and HOA restrictions push RVs and trailers off residential driveways — yet almost no new enclosed inland dry-stack capacity has been added in most metros. The opportunity is real. But these are operationally intensive, capital-heavy projects, and the difference between a fundable deal and a stranded one is a demand model and risk analysis that survive underwriting.
| Indicator | Figure | Read-through |
|---|---|---|
| Registered recreational boats, Florida | ~970,000 (#1 nationally) | Florida accounts for roughly 11.8% of all U.S. recreational vessel registrations (~11.6M nationally). |
| Boats per 1,000 residents, Florida | ~42.5 (#1 state) | More than double the national average of ~18 per 1,000 residents. |
| Marine industry economic impact | ~$34B annually, ~240,000 jobs | Boating is a structural industry in Florida, not a discretionary sideline. |
| National registration growth outlook | ~2%–3% per year through 2028 (NMMA) | The demand base keeps compounding while wet-slip supply contracts. |
| Florida population growth | ~350,000–400,000 net new residents per year | In-migration from high-tax states brings boat- and RV-owning households with it. |
| Coastal market penetration (example) | ~63 boats per 1,000 residents in the Sarasota–Manatee MSA | Roughly 3.5× the national average — the densest boating markets in America are on Florida’s coasts. |
Every one of those boats needs to live somewhere when it is not on the water. Trailerable boats in the 12–39.9-ft range — the core dry-stack demand class — dominate the fleet, and a meaningful share of their owners cannot or will not store them at home.
Four structural forces are driving the gap between storage demand and storage supply in Florida:
| Driver | What is happening | Storage implication |
|---|---|---|
| Wet-slip supply contraction | Waterfront marina parcels keep converting to condos and mixed-use; hurricane losses permanently retire dock capacity. | Displaced boats need dry storage; enclosed dry-stack is the premium substitute. |
| Insurance dislocation | After Hurricanes Ian (2022) and Idalia (2023), Southwest Florida waterfront marina operators saw premium increases of roughly 40%–120%. | Inland FEMA Zone X sites carry a material insurance cost advantage — in one recent engagement, an estimated $200,000–$450,000 per year versus a comparable waterfront facility. |
| HOA and municipal restrictions | Deed restrictions across Florida’s master-planned communities prohibit boats, RVs, and trailers in driveways. | An independent, non-boating demand pool for enclosed and covered RV/trailer storage. |
| Owner willingness to pay | Marina Dock Age 2025 data shows Gulf Coast enclosed dry-stack rates compounding 4.8%–5.4% annually over 2022–2025, with median stabilized occupancy around 92%. | Pricing power is real where supply is exhausted — but it must be evidenced, not assumed. |
A recent Wert-Berater feasibility engagement for a proposed enclosed inland dry-stack boat and RV storage facility on Florida’s Gulf Coast illustrates how tight these markets have become. The two-county Sarasota–Manatee market holds 52,614 total registered vessels (FLHSMV Annual Vessel Report 2024), of which roughly 42,186 are trailerable boats in the 12–39.9-ft range. The two-county fleet grew 12.6% over 2020–2025 — while zero new enclosed dry-stack capacity was added to the primary market area in the same period.
The most material finding was not a statistic from a database. It was a June 2026 mystery-shop survey of eight competitive storage facilities: fewer than 10 total available units across all eight, with five of eight reporting a waitlist or zero availability. The two highest-quality enclosed dry-stack facilities in the trade area — roughly 324 and 270 spaces respectively — both reported zero availability. That is what a supply-exhausted market looks like, and it is exactly the kind of primary evidence a lender can act on.
Storage demand cannot be read off a shelf. Wert-Berater builds it from vehicle registration data using a four-class demand model, applying a conservative off-site storage need rate and a commercial-pay rate to each class, then netting out the estimated existing supply. The example below is the actual model from the Gulf Coast engagement, applied to a 30-minute secondary market area (SMA):
| Demand class | Registered (SMA) | Off-site storage need | Commercial pay rate | Demand (spaces) |
|---|---|---|---|---|
| Trailerable boats, 12–39.9 ft | 42,186 | 14.8% | 75% | 4,683 |
| Travel trailers | 10,018 | 15.0% | 70% | 1,052 |
| Vehicle trailers (boat-trailer subset, 8%) | 83,983 | 8% subset | 40% | 2,687 |
| Motorhomes | ~8,400 | 20.0% | 70% | 1,176 |
| Total SMA base demand | — | — | — | 9,598 |
| Less: estimated existing SMA supply (all types) | — | — | — | (4,050) |
| Net unmet SMA demand | — | — | — | 5,548 |
Against a net unmet primary-market demand of roughly 3,550 spaces (the same model applied to the tighter 15-minute primary market area within the SMA above), the subject facility’s 350 units represented a required capture of about 9.9% — a modest share in a market where the alternatives are full. That is the shape of a defensible demand case: conservative rates at every step, an explicit supply deduction, and a required capture rate low enough that moderate error does not break the deal. When the model only works at 40% capture, it does not work. See our deeper treatments of trade-area definition and capture rate analysis.
Wert-Berater develops inland marine and RV/boat storage feasibility studies to the standard the financing program demands — for SBA 504 transactions, that is SBA SOP 50 10 8 (effective June 1, 2025), which requires an independent assessment across five dimensions:
| Dimension | What we test for a storage project |
|---|---|
| Economic feasibility | National, state, and MSA economic context; boat/RV ownership penetration; in-migration; insurance market dynamics; discretionary spending drivers. |
| Market feasibility | Registration-based four-class demand model; primary/secondary market area definition; competitive census with field verification (mystery-shop); rate survey against Marina Dock Age and local comps; required capture rate. |
| Technical feasibility | Site zoning and by-right use confirmation; FEMA flood zone; building system (pre-engineered metal building wind rating, rack configuration, forklift capacity); construction budget benchmarked per SF; timeline realism. |
| Financial feasibility | Ten-year pro forma with a conservative occupancy ramp; DSCR against the actual loan structure; ±5/10/15 sensitivity matrix; interest-rate stress testing; break-even occupancy; downside scenarios. |
| Management feasibility | Operator experience, staffing plan, management agreements, and concentration risk — storage is an operating business, not passive real estate. |
Three habits separate a lender-grade study from a marketing document. First, conservatism is built into the base case: in the Gulf Coast example, Year 1 occupancy was modeled at 58% with stabilization at 88%–92%, a 5% vacancy and credit-loss allowance was applied, and ancillary income (membership premiums, wash-station fees) was excluded entirely. Second, every demand input traces to a named source — no data point originates solely from borrower projections without independent corroboration. Third, the financial model contains zero hardcoded numbers, so every stress scenario recalculates from the same linked assumptions the lender can audit.
Illustrative results from the same engagement show what underwriting looks for (figures specific to one project and one loan structure):
| Test | Result | Why it matters |
|---|---|---|
| Stabilized DSCR (Year 2) | 1.49x vs. the SBA 1.15x minimum | A 39% cushion above the floor at stabilization — the headline coverage number. |
| Sensitivity matrix (±15% rate × ±15% occupancy, 49 cells) | 48 of 49 combinations pass SBA minimums | Only the simultaneous extreme (rate +15% and occupancy −15%) dipped below, by 0.01x. |
| Interest-rate stress (+0.5% to +2.5%) | All five stress scenarios pass; DSCR 1.30x at +2.5% | Quantifies how much rate risk the structure absorbs before coverage thins. |
| Break-even occupancy | 83.6% at stabilization for DSCR = 1.00x; 52.8% in the interest-only Year 1 | Tells the lender exactly how much lease-up shortfall the deal survives. |
| Occupancy assumptions vs. market | 92% stabilized — the Marina Dock Age median for comparable Gulf Coast enclosed dry-stack operators | Assumptions anchored to published operator data, not aspiration. |
Note what the break-even line implies: at stabilization, the margin between the modeled occupancy and the SBA-compliant occupancy can be a handful of spaces. An honest study says so plainly — and recommends occupancy monitoring triggers in the loan agreement rather than hiding the thinness of the margin. Compare DSCR requirements across SBA, USDA, and conventional programs.
Storage projects fail for predictable reasons. A feasibility study that does not name these risks — with severity, probability, and a mitigation the lender can write into the loan agreement — is not finished:
| Risk | What can go wrong | Mitigation the study should specify |
|---|---|---|
| Lease-up pace | Year 1 occupancy runs behind the ramp; a construction delay misses the fall pre-leasing season. | Formal pre-leasing campaign starting six months before certificate of occupancy; target documented competitor waitlists; maintain a prospect database as lender evidence; interest-only Year 1 to lower the early break-even. |
| Construction cost escalation | Steel and PEMB material costs move beyond the contingency; tariff exposure. | Fixed-price GMP contract, early steel procurement, owner’s contingency reserve, cost certification. |
| Interest-rate movement | A variable-rate first mortgage erodes DSCR toward the program floor. | Fixed-rate structure or rate-cap covenant; document the rate sensitivity in the credit memo. |
| New competition | A large marina chain replicates the inland dry-stack model in the trade area. | Test the replication barrier: scarcity of appropriately zoned industrial parcels with the required clearance and access is a structural moat — or it is not. Verify the development pipeline independently. |
| Hurricane / wind | Direct wind damage to the structure even on a non-flood site. | Hurricane-rated PEMB per the Florida Building Code; inland FEMA Zone X siting to remove storm-surge exposure and cut insurance cost; adequate windstorm coverage. |
| Environmental | A stale Phase I ESA hides recognized environmental conditions. | Current ASTM E1527-21 Phase I before closing — a Phase I more than 12 months old should be a named condition, not a footnote. |
| Recession / demand softness | Boat usage falls; storage contracts churn; pricing pressure. | Annual contracts to lock revenue; membership/service overlays to reduce churn; a break-even occupancy low enough to ride out a soft year. |
| Program compliance (SBA) | Passive-business determination; management-fee eligibility; guaranty structure. | Engage SBA counsel pre-application; document active operating character (launch/retrieval service, staffing); confirm fee eligibility with the CDC. |
| Management concentration | One entity holds both the development and property management roles. | Disclose the concentration, benchmark the fees, and document borrower oversight rights. |
Build only where most of these are true: a registration-derived demand gap several times the project’s capacity; field-verified competitor waitlists or zero availability; required capture under ~15%; industrial zoning that permits the use by right; FEMA Zone X or equivalent insurance-advantaged siting; a fixed-price construction contract; a debt structure whose break-even occupancy sits well below the market’s demonstrated stabilized level; and an operator with a real staffing and service plan. When a project checks those boxes, Florida’s boat and RV storage fundamentals are among the strongest of any special-purpose asset class. When it does not, no statewide statistic will save it.
Every claim above — the demand gap, the capture rate, the occupancy ramp, the coverage cushion — has to survive underwriting against a specific site and a specific loan structure. That is what an independent feasibility study is for.
