The advertised price for a Puerto Banús yacht charter and the figure you actually pay at the pontoon are often two different numbers, and the gap is usually called a fuel surcharge. In 2026, with marine diesel hovering around €1.55-€1.85 per litre on the Costa del Sol, that surcharge can add 20-40% to a quoted rate. This guide explains how the surcharge is calculated, why it exists, and why our charters — bookable through the Boat Rental Marbella hub — do not use one.
What a fuel surcharge actually is
A fuel surcharge is a line item added after the base hire. It can be structured three ways: a flat percentage (commonly 25-35%) of the charter price, a per-litre charge based on the boat's actual consumption that day, or a fixed euro amount per engine hour. The first model is most common in Puerto Banús because it is simplest to quote over WhatsApp. The second is more honest but requires trust in the operator's logbook. The third sits somewhere in between.
Either way, the surcharge is real money. A €1,200 half-day on a 14m flybridge can become €1,560-€1,680 once a 30-40% surcharge lands. Guests rarely see the breakdown until the final invoice.
Why marine diesel costs more than road diesel
Marine fuel in Spain is sold under different tax and logistics conditions than the diesel you put in a hire car. Pontoon delivery, lower turnover at marina pumps, and supplier margin on small-volume sales all push the price up. In June 2026 at Puerto Banús, expect €1.55-€1.85 per litre depending on supplier and whether you fuel from the pump or a bunker truck. Estepona and Sotogrande sit in the same band; Cabopino is sometimes a few cents cheaper.
That premium of roughly 25-30% over road diesel is the underlying reason surcharges exist. Operators either absorb it (and price it into the headline rate) or pass it through.
How much fuel a Marbella charter actually burns
Consumption depends on hull type and speed. Rough figures for the kind of boats you see in Puerto Banús:
| Boat type | Cruise speed | Litres / hour |
|---|---|---|
| Sailing catamaran (Lagoon 380) | 6-8 kts under engine | 4-8 |
| Small RIB / speedboat (7m) | 20-25 kts | 20-35 |
| 12m planing motor yacht (Azimut 39) | 18-22 kts | 80-120 |
| 14-18m flybridge (Pershing 46, Azimut 58) | 22-26 kts | 150-260 |
| 24-29m superyacht (Mangusta 80, Ferretti 94) | 22-28 kts | 250-450 |
A four-hour trip on an Azimut 39 cruising mostly at 20 kts will therefore burn roughly 350-450 litres. At €1.70/L that is €595-€765 of fuel. You can see why operators on tight margins want this off their own balance sheet.
How our pricing avoids the surcharge
We build an average consumption figure into the headline rate based on a typical Marbella itinerary — a mix of cruise, drift, swim stops and a short blast back to port. For our Tier A boats (Astondoa 40 and Azimut 39), that lands at €749 for two hours rising to €2,299 for a full eight hours, fuel included. For the Mangusta 80 it is €4,719 for a four-hour minimum, with a jet ski thrown in free.
This works because we run our own boats from Puerto Banús and know what each itinerary actually costs. We are not reselling someone else's hull and trying to predict their fuel bill. For peak-season nuance see our note on August chartering.
What is included alongside fuel
- Licensed Spanish skipper for the whole charter
- Soft drinks, beer, white wine and cava on ice
- Light snacks — olives, crisps, fruit
- Full insurance and safety equipment
- Spanish IVA at 21%
- Port departure and re-entry fees at Puerto Banús
The only thing not included is a tip for the skipper if you enjoyed the day, and any food beyond light snacks (we can arrange catering — see our dietary guide).
Other hidden fees to watch for elsewhere
If you are comparing quotes from multiple operators, ask specifically about: port re-entry fees (sometimes €40-€80 extra at peak times), end-of-day cleaning fees (€60-€150), ice and drink top-ups, IVA shown separately at checkout, and "skipper gratuity included" wording that is then re-requested in cash. A €600 advertised half-day can stack to €900+ once these add up. We list one number on WhatsApp and that is the number you pay.
Sail vs motor: the fuel maths
If keeping fuel costs (or environmental footprint) low matters to you, a sailing catamaran is the obvious choice. Our Lagoon 380 uses 4-8 L/h under engine and zero under sail. A summer afternoon from Puerto Banús to the anchorage off Río Verde and back might burn 15-20 litres total. Even at full surcharge pricing, that is negligible — but with us it is already in the rate.
Motor yachts are faster and more comfortable in chop, which is why most Marbella guests still choose them. The trade-off is fuel. Our all-inclusive pricing simply removes that variable from the decision.
Getting a surcharge-free quote
Message us on WhatsApp with your date, group size and what you want to do — a sunset cruise along the Golden Mile, a full-day run to Sotogrande, a swim-and-snorkel afternoon off Cala del Faro. We reply with the all-in euro figure, confirm the boat from our Puerto Banús fleet, and hold the slot. No fuel reconciliation invoice the next morning.
Frequently asked questions
What is a yacht fuel surcharge in Puerto Banús?
A fuel surcharge is an extra fee added on top of the advertised charter price to cover the diesel or petrol consumed during your trip. On the Costa del Sol it typically runs 20-40% of the base hire, sometimes calculated by litres burned, sometimes as a flat percentage. Our charters do not use this model — fuel is included in the headline rate, so the price you see on WhatsApp is the price you pay.
How much does marine diesel cost in Puerto Banús in 2026?
Marine diesel at Puerto Banús and nearby ports sits around €1.55-€1.85 per litre in 2026, depending on the supplier and whether you fuel at the pontoon or via bunker delivery. That is roughly 25-30% above road diesel because marine fuel is taxed and handled differently. This is why traditional operators pass the cost through as a surcharge rather than absorbing it.
How much fuel does a typical Marbella charter burn?
A 12m planing motor yacht like an Azimut 39 burns roughly 80-120 litres per hour cruising at 18-22 knots, and 25-40 L/h at displacement speed. Bigger flybridge yachts in the 24-29m range can burn 200-400 L/h at cruise. Sailing catamarans like our Lagoon 380 sip 4-8 L/h under engine and zero under sail, which is why sail charters rarely carry surcharges.
Do your prices include fuel?
Yes. Every charter we list includes fuel, a licensed skipper, soft drinks, beer, white wine, cava, light snacks, insurance, safety kit and Spanish IVA at 21%. The €749/2h Tier A rate and €4,719/4h Mangusta 80 rate are final — no fuel surcharge, no port fee bolt-on, no service charge added at the pontoon. See our pricing breakdown for peak-season context.
Why do some operators still charge fuel separately?
Two reasons. First, it lets them advertise a low headline price to win clicks, then recover margin at the dock. Second, fuel use genuinely varies — a flat-water cruise to Cala del Faro uses far less than a fast run to Sotogrande into a westerly. We solve this by building an average consumption figure into the rate, which works because our skippers know the routes and weather windows.
Can I ask the skipper to slow down to save fuel?
On a surcharge-based charter, yes — and many guests do, because every litre saved comes off their invoice. On our all-inclusive charters there is no financial incentive either way, so you can ask the skipper to run fast to Estepona for lunch or drift slowly along the Golden Mile without watching a fuel gauge. The price stays the same.
Are there other hidden fees on Puerto Banús charters?
Watch for port re-entry fees, cleaning fees, ice or drink top-ups, skipper gratuity expectations and IVA added at checkout. A €600 advertised half-day can become €900+ once these stack up. Our quote on WhatsApp is the all-in figure: fuel, drinks, snacks, skipper, IVA, insurance. The only optional extra is tipping the skipper if you enjoyed the day.
How do I get a final, surcharge-free quote?
Message us on WhatsApp with your preferred date, group size and rough itinerary (sunset cruise, full-day to Sotogrande, jet ski add-on, etc.). We reply with the all-inclusive total in euros, confirm the boat from our Puerto Banús fleet and hold the slot once you confirm. No deposit games, no fuel reconciliation invoice afterwards.
