Starting a small boat rental business in Marbella in 2026 is more straightforward than most prospective owners think — and more paperwork-heavy than the Boatsetter blog posts make it look. This page is the practical operator's view: legal structure, lista 6 setup, taxes, marina costs, realistic Year 1 ROI on a single-boat operation, and the three mistakes we see new owners make most often. If you already own a boat, the faster path is to list it through us — same revenue model, far less admin.
Two paths: own + list, or own + self-operate
Path A — own and list with a local manager (us, or competitors like Sotogrande Charter, Marbella Yacht). You handle insurance and lista 6; the manager handles bookings, screening, despacho, check-in/out, payments. Your effective tax setup is just lista 6 + IVA declaration; you don't need to register as a charter business yourself in most cases (the manager invoices the renter under their business).
Path B — own and self-operate as a chartered business. You register as autónomo or set up an SL, become the legal charter operator, invoice renters directly, file IVA, manage marketing, take the calls. Higher ceiling, much higher admin load. Worth it from about 3 boats up.
Most owners start with Path A on their first boat, build a season of data, then decide whether to expand. This page walks through Path B because that's the question the search query 'boat rental business' is asking.
Legal structure: autónomo or SL
| Structure | Setup cost | Monthly cost | Tax rate | Best for |
|---|---|---|---|---|
| Autónomo (self-employed) | ~€0 (just register) | €80–€350 cuota | IRPF 19–47% on profit | 1 boat, <€60k/yr revenue |
| SL (Sociedad Limitada) | €3,000 capital + ~€1,200 notary | €60–€100 accountant | 25% corporate (15% first 2 yrs) | 2+ boats or >€60k/yr |
Autónomo lets you start fast — register online via Hacienda's Modelo 036, pay the monthly cuota, declare income quarterly (Modelo 130 for IRPF, 303 for IVA). The downside: personal liability for everything, and at higher revenue the IRPF tops out at 47%, which beats the 25% SL rate.
SL gives you liability separation (a renter accident claim hits the company, not your house) and corporate tax. Worth it when projected annual profit exceeds about €30,000.
Lista 6 and the technical inspection
The vessel must be registered as lista 6 (commercial / charter) before a single paying renter steps aboard. Process:
- Submit lista change request to Capitanía Marítima (Málaga or Estepona office). €120–€280 in fees.
- Book a technical inspection (ITB) with Bureau Veritas, Lloyd's, DNV or RINA. Cost €350–€900 depending on length. Covers structural, fire, electrical, life rafts, EPIRB, flares, MOB equipment.
- If pass, new lista 6 certificate issued. If fail (common items: out-of-date flares, missing fire blanket, EPIRB battery dead), fix and re-inspect.
- Update insurance to charter cover — see our insurance page.
- Despacho de salida required for each paid charter, lodged with Capitanía 24–48h ahead. We file these for managed boats.
ITB renews every 5 years for vessels under 24 m, every 3 years for 24 m+. Build the renewal cost (€400–€1,200) into your Year 5 reserve.
Marina berth costs in Marbella
Commercial (charter) berth rates are 10–25% higher than private rates because the marina knows the boat moves more. Indicative 2026 annual rates:
| Marina | 10 m | 14 m | 20 m | Notes |
|---|---|---|---|---|
| Puerto Banús | €18,000–€24,000 | €26,000–€36,000 | €48,000–€78,000 | Waiting list. Best walk-in traffic. |
| Marbella Marina (Puerto Deportivo) | €11,000–€16,000 | €18,000–€26,000 | €34,000–€52,000 | Quieter, cleaner, often available. |
| Cabopino | €9,000–€13,000 | €15,000–€22,000 | €30,000–€45,000 | Smaller, east of Marbella, parking easy. |
| Estepona | €8,000–€12,000 | €14,000–€20,000 | €28,000–€42,000 | Growing — see our main page. |
| Sotogrande | €10,000–€15,000 | €16,000–€23,000 | €32,000–€48,000 | Upmarket, lower charter density. |
If you list with us, we have berth-sharing arrangements with Marbella Marina and Cabopino that cut costs by ~25%. Ask.
Year 1 ROI scenarios
Two realistic scenarios, owner-operated (Path B), single boat, Marbella Marina berth, charter insurance, full IVA accounting:
| Scenario | 10 m Astondoa-class | 14 m Sunseeker-class |
|---|---|---|
| Purchase price | €220,000 (used) | €620,000 (used) |
| Gross charter revenue (Year 1) | €42,000 | €88,000 |
| Less: IVA payable (net of recoverable) | €4,800 | €10,500 |
| Less: marina (commercial) | €13,500 | €22,000 |
| Less: insurance (charter) | €2,400 | €4,200 |
| Less: maintenance + antifouling | €3,500 | €7,000 |
| Less: skipper days (50% of charters) | €3,800 | €5,500 |
| Less: cleaning, fuel pass-through net | €1,800 | €3,200 |
| Less: autónomo cuota + accountant | €2,800 | €2,800 |
| Net before financing | €9,400 | €32,800 |
| ROI on boat (net) | 4.3% | 5.3% |
Honest take: Year 1 net rarely covers a finance payment if you bought the boat on a loan. Year 2–3 typically grows revenue 25–40% as reviews accumulate and you raise rates. The boats that genuinely pay for themselves are the 18 m+ crewed yachts running 60+ charter days at €2,800–€4,500 day rate.
The three mistakes new operators make
- Underinsuring hull value to shave €200–€400 off the annual premium. A €280k boat insured at €180k pays out at €180k after a grounding. We've seen this twice in the last three years; both owners ate the gap.
- Skipping the despacho on a 'quick hop, no big deal' charter. Guardia Civil boards roughly once a season. Fines €600–€3,000 plus charter suspended. Always file.
- Bareboat-renting without verifying the PER. Spanish PER is required for any vessel over 5 m / 15 hp; renter shows you a card, you assume valid, the card expired 14 months ago. Charter happens, dinghy hits a swimmer, insurer disputes coverage. Photograph and verify the PER every time.

Frequently asked questions
Can a non-Spanish resident start a boat rental business in Marbella?
Yes. EU citizens register as autónomo or set up an SL the same as residents. Non-EU owners need either a Spanish company (SL with a Spanish administrator), a Spanish representative, or to operate through an existing local management company like ours. NIE number is required either way — apply at the Spanish consulate before arriving.
Autónomo or Sociedad Limitada (SL) — which?
Autónomo (self-employed) for revenue under ~€60,000/yr — simpler, monthly cuota ~€80–€350, no minimum capital. SL for revenue above that or if you want liability separation — €3,000 capital, ~€800/yr accountant, corporate tax 25% (15% first two years). Most single-yacht owners start autónomo and convert if the business grows.
What does lista 6 setup actually cost?
Notary and Capitanía Marítima filings €120–€280, technical inspection (ITB) by Bureau Veritas / Lloyd's / DNV €350–€900 depending on length, despacho stamp duty €40, name change on register €60. Total: €570–€1,280. Allow 4–8 weeks. Add €300–€800 for an asesor náutico if you don't speak Spanish.
How much VAT do I pay on charter revenue?
21% IVA on the daily rate, charged to the renter (renter pays €749 + €157 IVA = €906 displayed price). Declared quarterly via Modelo 303 by the 20th of January, April, July and October. You also recover IVA on charter-related expenses: fuel, insurance, maintenance, marina fees. Net IVA payable is rarely the full 21%.
Do I need a captain's licence to charter my own boat?
To skipper a paid charter on a vessel up to 24 m / 150 GT, you need at least Patrón de Yate (Spanish) or an equivalent ICC + STCW certificate. For up to 12 m and 30 NM from coast, Patrón de Embarcaciones de Recreo (PER) is enough on paid charter as long as the vessel itself is properly licensed. PER takes ~3 months and €600–€1,200 in Marbella schools.
What's the realistic ROI on a 10–14 m charter yacht?
Year 1 a well-listed 10–12 m motor yacht clears €18,000–€35,000 net (gross €28,000–€55,000, less commission, fuel pass-through, insurance, marina, maintenance reserve). Year 2 with established reviews and repeat renters typically adds 25–40%. ROI on the boat purchase: 6–11% gross, 4–7% net. Won't pay the boat off — will pay its operating costs and a useful surplus.
Where should I berth the boat?
Puerto Banús: highest charter demand, highest berth cost (€18k–€42k/yr for 10–14m), best walk-in traffic. Marbella Marina / Puerto Deportivo: ~30–40% cheaper, less walk-in but cleaner operation for skippered charters. Cabopino, Estepona, Sotogrande: cheaper still, easier parking, less weekend demand. We can help negotiate.
What's the most common mistake new owners make?
Underinsuring hull value to save €200–€400/yr on the premium. The €280k Astondoa insured at €180k pays out at €180k after a grounding — owner eats the gap. Second most common: skipping the despacho on a 'short hop, no big deal' charter, then getting boarded by Guardia Civil and paying €600–€3,000 in fines. Third: bareboat-renting to someone whose PER turns out to be expired.
