When choosing between the Astondoa 40 and the Azimut 39 for a Marbella charter, fuel cost is often a hidden concern. Both vessels depart from Puerto Banús and share the same all-inclusive rate of €749 for 2 hours and €2,299 for 8 hours, covering fuel, skipper, drinks, snacks, insurance, and 21% IVA. But how do their fuel consumption figures compare, and does it matter for your wallet? This guide breaks down the numbers so you can book with confidence.
Astondoa 40: Specs and Fuel Burn
The Astondoa 40 measures 12.5 metres and carries up to 9 passengers. Powered by twin diesel engines (typically Volvo Penta D4-260 or similar), it cruises at 20-25 knots with a fuel consumption of 80-100 litres per hour. At top speed (28-30 knots), burn rises to 120 L/h. For a 2-hour charter, you'll use roughly 160-200 litres; for 8 hours, 640-800 litres. At current diesel prices (approx. €1.50/L in Marbella), the fuel cost alone would be €240-€300 for 2 hours and €960-€1,200 for 8 hours — but you pay none of this because it's included.
Azimut 39: Specs and Fuel Burn
The Azimut 39 is also 12.5 metres but can accommodate 11 passengers — two more than the Astondoa. Its twin engines (often Caterpillar 3126 or similar) deliver slightly higher power, resulting in a cruising fuel consumption of 90-110 litres per hour. At full throttle (30+ knots), it can exceed 130 L/h. Over 2 hours, expect 180-220 litres; over 8 hours, 720-880 litres. The fuel cost would be €270-€330 for 2 hours and €1,080-€1,320 for 8 hours — again, fully covered by your flat rate.

Why Fuel Is Included: The Marbella Charter Model
Unlike some destinations where fuel is a surcharge, Marbella charters operate on a fully inclusive model. The €749/2h or €2,299/8h rate covers everything: skipper, fuel, water, soft drinks, beer, white wine, cava, light snacks, insurance, and Spanish VAT. This means fuel consumption differences between the Astondoa 40 and Azimut 39 have zero impact on your final bill. You pay the same regardless of how far you go or how fast you cruise. This model is standard across all our boats, from the Boat Rental Marbella fleet.
Which Boat Should You Choose Based on Fuel?
Since fuel cost is identical for both charters, your decision should rest on passenger capacity and onboard experience. Choose the Astondoa 40 if your group is 9 or fewer and you prefer a slightly more fuel-efficient, quieter ride. Opt for the Azimut 39 if you have 10-11 guests, as it offers two extra seats without a price penalty. Both boats provide similar deck space, sunbathing areas, and amenities. For larger groups (up to 12 pax), consider the Azimut 58 Flybridge at 17.6m.
Practical Tips to Maximise Your Charter
- Plan your route: A 2-hour charter covers Marbella coastline to Cabopino or Cala del Faro. For 8 hours, head to Estepona (15 NM) or Sotogrande (25 NM).
- Bring your own music: Both boats have Bluetooth audio systems.
- Book in advance: Summer weekends sell out quickly. Check availability for the Astondoa 40 or Azimut 39.
- Consider the weather: Calm seas favour both boats; the Azimut 39 handles slightly better in chop due to its modified-V hull.
Other Fuel-Efficient Options in Our Fleet
If you're particularly cost-conscious, our smaller boats like the Speedboat (7m, 6 pax) or Mariah SX21 (6.4m, 5 pax) offer lower rates (pricing on request) with proportionally less fuel consumption. For a unique experience, the Bandido (11.5m, 8 pax) is a classic wooden boat with efficient diesel engines. All charters include fuel, so you never worry about the pump.

What is the fuel consumption of the Azimut 39?

Which boat is more fuel-efficient: Astondoa 40 or Azimut 39?
The Astondoa 40 is marginally more fuel-efficient, burning about 10-15% less fuel per hour at comparable speeds. However, since fuel is included in the charter price, the difference does not affect your cost. The Azimut 39 offers better per-person value with 11 pax vs 9.

No, we do not offer discounts for bringing your own fuel. The all-inclusive pricing structure is standard for Marbella charters, covering fuel, skipper, and all extras. This simplifies budgeting and avoids any surprises.

The Azimut 39 is the better choice for groups of 10, as it has a maximum capacity of 11 passengers. The Astondoa 40 maxes out at 9 pax. Both boats are similar in length (12.5m), so comfort levels are comparable for smaller groups.
