Power Catamaran Running Costs: The Real Numbers

What it actually costs to own and berth an OceanWalker in the Mediterranean.
Guides · Ownership Costs
Buyers researching power catamaran running costs are usually months from placing a deposit and want a defensible answer to what a boat like the OceanWalker S60 actually costs to own before committing €3.2M. This page sets out real, itemised power catamaran running costs across European Yacht Brokers’ Mediterranean territory — France, Italy, Spain, Portugal, Croatia, Greece, Cyprus and Malta — rather than a generic industry percentage, so a serious buyer can see where the money goes: berthing, fuel, insurance, maintenance, VAT and registration, and how charter income can offset a meaningful share of the total.

Fast facts:

  • Total power catamaran running costs for an owner-operated OceanWalker S60 typically run €72,000–€158,000 a year — roughly 2%–5% of the €3.2M purchase price, before charter offset and one-time VAT.
  • Mediterranean marina berths for an 18–19 m, 8+ m-beam catamaran typically run €20,000–€45,000 a year on an annual contract, arranged by European Yacht Brokers as part of every sale.
  • Insurance is an industry rule-of-thumb estimate of 0.6%–1.5% of insured value — roughly €19,000–€48,000 on the S60, to be confirmed by an actual quote.
  • The S60's optional 22-panel, 9 kW solar array doesn't reduce main-engine fuel burn, but it cuts generator runtime for hotel loads at anchor.
  • EU VAT on yacht importation typically runs 17%–25% by country, and the agency prepares this documentation as part of every sale.

Berthing and marina fees across the Mediterranean

Berthing is usually the first line item buyers ask about, and it's also the one where power catamaran running costs vary most by location. Marinas price berths chiefly by beam as well as length, and the S60's 8.38 m beam puts it in a wider pricing band than a monohull of the same 18.87 m (60 ft) LOA. Published day rates for yachts in the 12–20 m class typically run €3–€6 per metre per day on a transient basis — well over €20,000 across a high-season month if paid nightly. Owners who berth permanently do better: an annual contract at a marina such as Palma, Cannes, Limassol or Split typically brings that down to €20,000–€45,000 a year, depending on country, marina prestige, and whether the berth is wet year-round or seasonal only.

This is one part of power catamaran running costs a buyer working with European Yacht Brokers doesn't have to shop for alone. Mooring is arranged as part of every sale across the agency's territory — France, Italy, Spain, Portugal, Croatia, Greece, Cyprus and Malta — so the berthing line above reflects real contracted rates the agency negotiates on an owner's behalf, not a number a first-time buyer has to discover by cold-calling harbour offices.

Fuel costs and the S60's twin Volvo Penta D6-440s

Propulsion is the second major variable in power catamaran running costs, and it depends far more on how a boat is used than on any single spec line. The OceanWalker S60 is fitted with twin Volvo Penta D6-440 diesel engines producing 880 hp combined, giving a genuine cruising boat capable of covering real Mediterranean distances rather than one built purely for marina-to-marina hops. For an owner-operated S60 doing typical seasonal cruising — long weekends, a few weeks in high season, occasional longer passages within the boat's roughly 1,500 nm range — fuel typically represents a smaller share of total running costs than berthing, insurance or maintenance, since most owners at this size cruise at moderate speeds rather than sustained wide-open throttle.

Where the S60's specification genuinely moves the needle on power catamaran running costs is hotel load, not propulsion. The optional 22-panel, 9 kW solar array doesn't reduce fuel burn on the main D6-440 engines, but it materially cuts how often the 32 kW generator needs to run at anchor to power air conditioning, refrigeration and house systems. Less generator runtime means less generator fuel, fewer service hours logged, and a lighter maintenance interval on a second engine owners often forget to budget for at all, a theme covered in more depth on this site's solar-assisted yachts guide. For an owner who anchors out often on passage between marinas, rather than staying dockside on shore power every night, that difference in generator hours compounds meaningfully across a full Mediterranean season, and it's one of the more overlooked levers on genuine power catamaran running costs.

Insurance: a rule of thumb, not a guaranteed number

Insurance is one of the more misunderstood parts of power catamaran running costs because it's so often quoted as a single hard percentage. The honest industry rule of thumb for hull and machinery cover on a well-maintained yacht in this class is roughly 0.6%–1.5% of insured value per year, varying with cruising ground, claims history, age of vessel, and whether it's used privately, chartered, or both. Applied to the S60's €3.2M price, that suggests an annual premium of €19,000–€48,000 — wide enough that buyers should treat it as a planning estimate, not a quote, and get an actual premium confirmed before finalising a budget. Specialist marine insurers such as Pantaenius publish general guidance on how hull value, use and cruising area affect premiums.

European Yacht Brokers doesn't underwrite insurance directly, but as part of every sale the agency can introduce buyers to marine insurance options suited to the S60 and the country of registration, so a new owner isn't starting that search from zero.

Maintenance, haul-out and VAT/registration

Routine maintenance and haul-out make up the least glamorous but most consistent line in power catamaran running costs. Industry rule-of-thumb guidance — echoed by brokers and marine insurers across the sector — puts annual maintenance at roughly 10% of purchase price when treated as a single all-in figure; broken out on its own, routine maintenance and haul-out for a boat in the S60's class typically runs €25,000–€45,000 a year, varying with engine hours, local labour rates and how proactively an owner stays ahead of the service schedule.

VAT and registration are a separate, mostly one-time consideration rather than an annual running cost, but they affect the real total cost of getting on the water. EU VAT rates on yacht importation vary by member state, commonly 17%–25%, and official European Commission guidance on the rules for private boats sets out how temporary admission and VAT-paid status work between territory countries. European Yacht Brokers prepares this documentation as part of every sale.

Offsetting running costs with charter

For many owners across this site's Mediterranean territory, charter is the single biggest lever on real power catamaran running costs — not because it eliminates them, but because it converts an idle asset into partial income during weeks the owner isn't using the boat. A worked example: if an S60 owner charters the boat for 8–10 weeks across a Mediterranean high season, gross charter income can realistically offset €40,000–€120,000 of the estimated €72,000–€158,000 in annual running costs set out above — in a strong season, covering the majority of berthing, insurance and maintenance combined, before charter management fees and extra wear.

This isn't a guarantee, and charter income depends heavily on marketing, location and season, but it's a real and commonly used strategy among owners in this class — the same charter-offset theme covered in full in this site's charter management for owners guide. Owners considering this route should factor in charter management commission, typically 15%–30% of gross revenue, and the additional wear a chartered boat sees versus a private-use-only vessel, both of which reduce the net offset below the gross figure. Even a conservative, lightly-chartered season can meaningfully change the real annual power catamaran running costs a buyer ends up carrying, which is why this line deserves the same upfront planning as berthing or insurance rather than being treated as an afterthought.

Total power catamaran running costs: the real annual number

Pulling the sections above together, total power catamaran running costs for an OceanWalker S60 in owner-operated Mediterranean use — berthing, insurance, maintenance and haul-out, and seasonal fuel — typically land between €72,000 and €158,000 a year, or roughly 2%–5% of the boat's €3.2M purchase price, before any charter offset and before VAT, which is a one-time cost rather than annual. That's meaningfully below the blanket “10% of purchase price” figure often quoted across the wider yacht market, largely because the S60 is typically owner-operated or run with day crew only rather than carrying a full-time paid crew, the single largest cost driver on larger crewed yachts and one that adds tens of thousands of euros a year the moment it's introduced.

Buyers should treat every figure on this page as a planning range, not a fixed quote — actual power catamaran running costs depend on cruising hours, country of berthing, insurance history and claims record, and how much of the season the boat spends chartered versus privately used. YachtWorld's independent research on the real cost of yacht ownership reaches a similar conclusion across the wider market, a useful sanity check against the S60-specific numbers above.

Power Catamaran Running Costs FAQ

Is a power catamaran cheaper to run than a monohull of similar size?

Generally, yes — power catamarans typically cost less to maintain than a monohull of similar length because they carry no mast, standing rigging or keel to service. That said, this is a general multihull-versus-monohull comparison rather than an S60-specific data point; twin-engine costs and beam-based berthing fees can offset some of that saving, so treat it as a directional advantage rather than an exact percentage.

What's included when buying a power catamaran through European Yacht Brokers?

Every sale includes VAT and registration documentation, delivery to the buyer's chosen country within the agency's territory, a mooring arranged on the buyer's behalf if needed, and an introduction to maintenance and insurance options — so the running-cost items on this page aren't left for a new owner to arrange alone.

How does berthing get arranged for a new owner?

European Yacht Brokers negotiates and arranges the mooring contract directly with the marina as part of every completed sale, using established relationships across the agency's Mediterranean territory rather than leaving a first-time buyer to negotiate a berth cold.

Does the agency handle ongoing maintenance after the sale?

Yes — ongoing maintenance can be coordinated by European Yacht Brokers on the owner's behalf, from routine servicing and haul-out to larger refit work, so a boat bought through the agency has a maintenance path already in place.

What's the biggest single driver of power catamaran running costs?

For most owner-operated boats in this class, berthing and maintenance together represent the largest predictable share of annual power catamaran running costs, with insurance close behind; full-time crew is the biggest variable, and most S60 owners avoid that cost by running the boat themselves or with day crew only.
