Marina Business Plan & Valuation: The 2026 Operator's Playbook

Marinas became an institutional asset class somewhere between 2018 and 2024. Sun Communities, Safe Harbor (Brookfield), Suntex, Storage Mart-adjacent platforms, and a dozen smaller PE roll-ups now compete with family operators to buy, build, and operate marinas. Cap rates compressed from 9.5% in 2018 to 6.5–7.5% in 2025. The capital is real, and it's here to stay.

Whether you're buying your first marina, evaluating an acquisition target, raising debt against an existing property, or selling — you need a defensible business plan, a real financial model, and an honest view of what your marina is worth. This is that playbook.

#Section 1: The business plan structure

A bankable marina business plan has 8 sections. Investors and lenders will read in this order:

1. 1Executive summary — 1 page. The pitch.
2. 2Market analysis — local boater demographics, competition, growth.
3. 3Property description — slips, infrastructure, ancillary assets.
4. 4Operating model — revenue streams + cost structure.
5. 5Financial projections — 5-year P&L, balance sheet, cash flow.
6. 6Capital structure — debt, equity, sources & uses.
7. 7Team — management experience and bench.
8. 8Risks + mitigations — honest assessment.

#Section 2: Revenue streams and the right mix

A pure-slip marina is the least valuable kind. The marinas that command premium valuations stack 5–8 revenue streams. Each adds margin AND increases customer lifetime value.

1. 1Annual slip rental — 35–55% of revenue at a typical marina. Recurring, predictable.
2. 2Transient docking — 8–18%. Higher per-night rate, seasonal volatility.
3. 3Fuel — 12–30%. Margin 32–42%. See [[fuel-dock-profitability-7-levers]].
4. 4Service / boatyard — 8–25%. Labor margin 55–65%, parts margin 25–35%.
5. 5Dry storage / dry stack — 5–15%. Highest margin per square foot of any service.
6. 6Ship store / retail — 2–8%. Margin 30–55%.
7. 7Other — pump-out, washdown, marina dining, broker referral fees, live-aboard fees.

#Section 3: The marina P&L (5-year model)

A realistic 200-slip coastal marina, fully built out with fuel + service + ship store + dry stack:

#Year 1 revenue (illustrative)

• Wet slips: 200 slips × $5,200/slip × 92% occupancy = $957K
• Transient: 1,800 nights × $135/night = $243K
• Fuel: 95,000 gallons × $4.85/gal = $461K
• Service / boatyard: $385K
• Dry stack: 110 spots × $4,400 × 95% = $460K
• Ship store: $148K
• Other: $52K
• TOTAL REVENUE: $2,706K

#Year 1 operating expenses

• Labor + benefits: $720K (26.6% of revenue)
• Cost of fuel: $293K (gross margin 36.4%)
• Cost of goods (service + retail): $190K
• Utilities: $115K
• Insurance: $145K (see [[marina-insurance-guide]])
• Property tax: $95K
• Marketing: $32K
• Repairs + maintenance: $145K
• Professional services + admin: $85K
• Other operating: $58K
• TOTAL OPERATING EXPENSES: $1,878K

#NOI + EBITDA

• NOI (Year 1): $828K (30.6% margin)
• Add-back: GM personal vehicle + small owner perks: $32K
• EBITDA: $860K

#Section 4: How marinas get valued

Three primary valuation methods. Most deals use a blend.

#Method 1: Cap rate on NOI

NOI ÷ Cap Rate = Enterprise Value. Using the example above: $828K ÷ 7.0% = $11.8M.

#Method 2: EBITDA multiple

EBITDA × Multiple = Enterprise Value. Using the example: $860K × 11x = $9.5M. (Note: lower than cap-rate method because EBITDA multiples already net out future capex needs that cap rates may not.)

#Method 3: Per-slip + ancillary uplift

200 slips × $40K/slip institutional benchmark = $8M base + ancillary premium 20–30% = $9.6M–$10.4M.

Blended: deal probably trades in $9.5M–$11.5M range, depending on buyer's strategy.

#Section 5: What moves cap rate up or down

Two marinas with identical NOI can trade 200 basis points apart on cap rate. The deltas:

#Things that LOWER cap rate (raise valuation)

• Coastal location with limited new-build supply.
• Long-term ground lease with renewal options OR fee simple title.
• Diverse revenue stream (5+ revenue lines).
• Audited financials, not just QuickBooks reports.
• Modern marina management software with clean reporting (Marine OS, Dockmaster, MS3, etc.).
• Documented SOPs and a stable management team.
• Mix of annual + transient (cash flow stability + upside).
• Recent capex completed — no big-ticket overhang.

#Things that RAISE cap rate (lower valuation)

• Spreadsheet-based ops, no auditable revenue history.
• Single revenue stream (slip rental only).
• Ground lease with <15 years remaining and no renewal.
• Significant deferred capex (dock replacement, fuel system, dredging).
• Single key person (owner-operator who IS the marina).
• Environmental contamination history.
• High customer concentration (single tenant = >10% of revenue).

#Section 6: Financing the deal

Marina debt is available but specialized. The active lenders in 2026:

1. 1Live Oak Bank — largest US marina lender. SBA + conventional. Down to $1.5M deals.
2. 2M&T Bank Marine — large bank with marine specialty group.
3. 3Wintrust Marine — Midwest focus.
4. 4BankFinancial — boutique, larger deals.
5. 5KeyBanc Marine — institutional.
6. 6Local community banks — for smaller deals ($500K–$3M), often the best terms IF the lender understands marina cash flow.

Typical terms in 2026:

• LTV: 65–75% (was 80% pre-2020).
• DSCR minimum: 1.30x–1.40x.
• Amortization: 20–25 years.
• Term: 7–10 years with balloon, or fully amortizing for smaller deals.
• Rate: SOFR + 250–400 bps (so ~7.5–9.5% in 2026 environment).

#Section 7: The buyer landscape in 2026

Who's buying marinas right now and what they'll pay:

#Institutional consolidators

• Safe Harbor Marinas (Brookfield-owned) — 140+ properties, focused on coastal premium.
• Suntex Marinas — 80+ properties, leisure-focused.
• Sun Communities Marinas — 130+ properties, often combined with RV.
• Westrec — 30+ properties, mixed strategies.
• Each pays full cap rate compression for institutional-quality assets.

#PE roll-ups (under-the-radar)

• Coral Reef Capital — 12+ properties.
• Cresco Capital — Pacific NW focus.
• Bluewater Capital — Midwest.
• Often pay slightly less than institutional but close faster.

#Family offices + individuals

• Pay less but can be flexible on terms (seller financing, earn-outs).
• Best fit for marinas <100 slips or specialty assets.

#Section 8: The 90-day pre-sale prep playbook

A marina that prepares for sale 12 months in advance typically nets 15–25% more than one that lists reactively. The 90-day quick wins:

1. 1Clean the books — separate personal expenses, normalize add-backs.
2. 2Migrate to modern marina software if still on spreadsheets — auditable trail.
3. 3Document SOPs in writing — buyer wants to see operational repeatability.
4. 4Take new photography (drone + dock-level + amenities).
5. 5Pre-order a Phase I environmental — preempt surprises.
6. 6Complete one cycle of customer agreements with current pricing — no surprises in revenue audit.
7. 7Settle any open litigation or claims.
8. 8Sign a confidentiality agreement template with broker.

#Section 9: The acquisition playbook (buyer side)

For operators buying their first or next marina, the diligence checklist that matters:

#Revenue audit

• 3 years of monthly revenue by stream.
• Customer roster with start dates, current rates, payment history.
• Retention cohorts — % of Year-1 customers still here in Year 3.
• Concentration risk — top 10 customers as % of revenue.

#Physical inspection

• Dock condition assessment by marine engineer.
• Underwater inspection of piles + utilities.
• Fuel system + UST/AST integrity.
• Electrical pedestals to ABYC standard.
• Building condition.

#Environmental

• Phase I ESA (always).
• Phase II if Phase I flags concerns.
• SPCC plan + compliance history.
• Storm water permit.

#Legal

• Title work.
• Survey + lease/easement review.
• Permits + zoning compliance.
• Pending or threatened litigation.
• Customer contract review for assignability.

#Section 10: Where the value-add lives

For a buyer with an operational thesis, the biggest sources of post-close NOI lift:

1. 1Software-enabled operations — 8–15% NOI lift from reduced labor + better collections + ancillary attach.
2. 2Pricing optimization — 6–12% lift from rationalizing legacy rates + dynamic transient pricing.
3. 3Ancillary expansion — adding service + dry stack + retail can lift NOI 20–40% over 3 years.
4. 4Occupancy lift — going from 78% to 90% on annual slips is often 8–15% revenue gain.
5. 5Energy + cost — LED lighting, solar, water reuse can save $30K–$80K/year.
6. 6Capex deferral resolution — fixing one big-ticket item often unlocks insurance reduction + premium pricing.

#A realistic 3-year IRR projection

For the 200-slip example above, a buyer at $10.5M purchase price + $1M improvements:

• Year 1 NOI: $828K → Year 3 NOI: $1,050K (27% lift via software + ancillary + occupancy).
• Exit Year 5 at 7.0% cap rate on $1,150K NOI: $16.4M.
• Total return on $11.5M invested: ~78% over 5 years, plus annual cash flow.
• Net IRR: 16–22% depending on debt structure.
