The real cost of owning a catamaran in Spain.
Catamarans cost more to keep than a monohull of the same length — and the reason is mostly the berth. Here is every 2026 line item: the beam surcharge on marina fees, wide-load haul-outs, two engines and two sail drives, insurance, 21% IVA, and how charter demand can pay some of it back.
The short version
A working figure for catamaran ownership in Spain is 9–13% of value per year — a notch above the 10% rule used for monohulls. A €450,000 production catamaran costs roughly €38,000–€55,000 a year; a €1.6M catamaran runs €190,000–€260,000 with crew.
The reason catamarans skew higher is not fuel or maintenance in isolation — it is the berth. A catamaran occupies close to twice the water area of a monohull of the same length, so Spanish marinas either charge by occupied area or apply a beam multiplier of around 1.5×, rising to 2× in premium Balearic marinas where wide berths are scarce. Haul-out and antifouling also cost more because there is roughly twice the wetted hull area, and there are two of everything below deck.
The offset: catamarans are the strongest charter asset in the Mediterranean. If you want the numbers before the sail-away, our catamaran prices guide covers what they cost to buy, and Lagoon vs Fountaine Pajot compares the two dominant builders.
Why catamarans cost more to keep
Every extra cost of catamaran ownership traces back to one physical fact: a catamaran is wide. A 45-foot monohull has a beam of around 4.5 metres; a 45-foot catamaran is closer to 7.5 metres. That near-doubling of footprint drives the three cost differentials that matter — berths priced by area, haul-outs that need wide lifts, and antifouling over twice the hull surface — before you count the second engine, second sail drive, and second set of systems.
None of this makes catamarans a bad buy. They are more stable, more spacious, and hold value well in a charter-hungry Mediterranean market. But an owner who budgets a catamaran as if it were a same-length monohull will be short by 20–40% every year. Plan for the beam.
Berth fees and the beam surcharge
This is the headline cost. Spanish marinas handle catamarans in one of two ways: they charge by occupied square metres (LOA × beam), or they apply a flat catamaran multiplier to the monohull rate. Either way you pay for the width. A realistic multiplier is 1.5× the monohull rate in most marinas, up to 2× in premium Balearic berths where catamaran-capable slips are scarce.
These figures exclude electricity, water and Wi-Fi, which most marinas meter separately — budget €200–€500/month for an actively used catamaran. The practical trap is availability, not price: in Palma, Ibiza and Barcelona the constraint is finding a catamaran berth at all. Secure the berth before you close on the boat, or you may own a catamaran with nowhere to put it. For the full picture across boat types, see our guide to berth and mooring costs in Spain.

Haul-out and antifouling
A catamaran cannot use a standard narrow travel-lift. It needs a wide-span lift or specialist slings, and not every Spanish yard is equipped for one — which both limits your options and lets qualified yards charge a premium. Lift-out and launch for a 45-foot catamaran typically runs €1,200–€3,500, at or above the top of the monohull range.
Antifouling is where the beam really shows up on the invoice. A catamaran has close to twice the wetted hull area of a monohull, so antifouling paint and labour scale accordingly — budget 40–80% more than an equivalent monohull for a full haul-out and antifoul. On the plus side, the flat working platform between the hulls makes some deck and rig work easier once the boat is out.
Two of everything
Below deck, a cruising catamaran is two boats bolted to a bridgedeck. That means two engines to service, two sail drives with seals that need replacing roughly every two years, two sets of anodes, two propellers, and often duplicated pumps, batteries and electronics across the hulls. Routine maintenance still lands around 2.5–4% of value per year for a production catamaran, similar to a monohull as a percentage, but the second engine and drive are the line items owners forget.
As with any boat in Spain, 21% IVA is added to every service, part and haul-out. A €12,000 twin-engine service is €14,520 once IVA is on it. The refit-year warning from the monohull cost guide applies with force here — every 5–8 years a significant refit can briefly push annual costs to 15–25% of value.
Insurance
As a percentage of insured value, catamaran premiums sit in the same band as monohulls: roughly 0.8–1.2% under €500k, 0.5–0.8% from €500k–€2M, and lower above that with professional crew and a clean record. Because a catamaran carries a higher value for a given length, the euro premium is larger than the same-length monohull — a €450k catamaran insures for around €3,600–€5,400 a year.
The variable that moves the number most is charter. A commercially coded charter catamaran pays 20–40% more than a private policy, reflecting heavier use and higher exposure. Mediterranean-only cover is the baseline; global or Atlantic-crossing extensions add 10–25%.
Fuel and running costs
A sailing catamaran under sail burns almost nothing; the fuel bill comes from motoring on two engines in light air and manoeuvring. A 45-foot cruising cat motoring at cruising revs burns roughly 8–14 litres per hour combined across both engines, so a typical Balearic season of 150–200 engine hours costs €2,000–€5,000 in diesel at 2026 Spanish prices of €1.65–€1.90/litre. Power catamarans are a different category entirely and burn far more.
Metered marina electricity and water add up quietly — a 14-metre catamaran running shore power and summer air conditioning across two hulls costs €150–€400/month. These small recurring items compound into €3,000–€5,000 a year that first-time owners routinely leave out of the budget.
IVA and the charter offset
Two tax points shape the economics. First, 21% IVA is baked into every marina fee and service (7% IGIC in the Canaries). Second — and this is the catamaran's advantage — cats are the most in-demand charter platform in the Mediterranean. Lagoon, Fountaine Pajot, Bali and Leopard models fill Balearic charter calendars, and a well-placed catamaran under professional management can recover a meaningful share of its annual running costs.
Charter is not free money. It requires commercial coding, a valid Spanish charter licence, VAT registration on charter income, and management fees of 10–15% of gross charter revenue. Private use by the owner is scrutinised by Spanish tax authorities and can jeopardise the commercial status. The VAT mechanics are covered in our Spain yacht VAT guide. Done properly, though, charter is the reason a catamaran's higher running cost is easier to carry than a monohull's.
Three real cost scenarios
All-in annual running costs in 2026, excluding depreciation and any charter income.
Scenario A: Lagoon 42, Valencia, owner-operated
Lagoon 42 valued at €450,000. Cat berth at Marina Real Juan Carlos I (€18,000). Insurance at 0.9% (€4,050). Maintenance including twin-engine service and antifoul (€11,000). Fuel, electricity and water (€3,000). Safety and tender (€1,500). Winterisation (€2,500).
Total: approximately €40,000/year — about 8.9% of value. The berth alone is nearly half the monohull equivalent's total.
Scenario B: Fountaine Pajot Saona 47, Palma, semi-active with light charter
Saona 47 valued at €900,000. Premium cat berth at a Palma marina (€42,000). Insurance at 0.65% (€5,850). Maintenance and rolling refit reserve (€28,000). Fuel (€6,000). Electricity and water (€3,500). Management fee (€8,400). Safety, tender, miscellaneous (€4,000).
Total: approximately €98,000/year — about 10.9% of value before charter income. A managed charter programme can offset a substantial slice of this.
Scenario C: Bali 5.4, Ibiza, full-time captain
Bali 5.4 valued at €1,700,000. Scarce premium cat berth in Ibiza (€60,000). Insurance at 0.55% (€9,350). Maintenance and refit reserve (€55,000). Fuel for 150 hours (€18,000). Full-time captain (€65,000 base plus social charges). Seasonal mate (€22,000). Management (€14,000). Provisions, flights, uniforms (€10,000). Safety and tender (€6,000). Flag fees (€5,000).
Total: approximately €260,000/year — about 15% of value. Catamarans run above the 10% rule at the top end, driven almost entirely by berth scarcity and crewed operation.
Frequently asked questions
Do catamarans really pay double for berths in Spain?
Not quite double, but close in premium marinas. Expect a 1.5× multiplier over the monohull rate as standard, and up to 2× in Palma, Ibiza and Barcelona where catamaran-capable berths are scarce and waitlisted.
Is a catamaran cheaper to run than a same-value monohull?
Usually slightly more expensive to run, because the berth and antifouling costs are higher. But a catamaran of the same length is worth more, so per euro of value the two are closer than they look. Where the catamaran wins is charter income potential.
Which Spanish marinas are best for catamarans?
For value, Valencia, Cartagena and Almerimar have more catamaran capacity at lower prices. The Balearic premium marinas have the fewest wide berths and the longest waitlists, so secure the berth before buying.
Can charter income cover a catamaran's running costs?
It can cover a meaningful share, sometimes most of it for a well-placed, well-managed boat, but rarely all of it once management fees, IVA on charter income, and owner-use restrictions are accounted for. Treat it as offset, not profit.
