Renting your own small boat is one of the easiest ways to explore Sardinia's coastline without joining an organized tour. Around the island, rental companies offer gommoni — rigid inflatable boats — that visitors can drive themselves without hiring a skipper.
The option most travelers see advertised is a 40 HP boat without a boating licence. That description is useful, but the Italian rule is slightly more precise than “40 HP means no licence.”
Can you rent a boat in Sardinia without a skipper?
Yes. Many Sardinian rental operators offer small motorboats and inflatable boats specifically for self-drive rental. A typical licence-free gommone is around 5–6 metres long, has an outboard engine close to 40 HP, and includes basic safety equipment, a sun canopy, ladder and cushions.
For example, operators in Cala Gonone advertise 40 HP inflatable boats that can be rented without a boating licence, making this a common option for exploring the Gulf of Orosei independently.
The Italian 40 HP rule explained
Under Italian recreational boating rules, a nautical licence is required within six nautical miles of the coast when the installed engine exceeds 30 kW, equivalent to 40.8 CV, together with the applicable engine-displacement thresholds.
This distinction matters: engine power is not the only technical parameter in the law. The engine's displacement and type also have to comply with the licence-free limits.
For travelers, the simplest rule is therefore: rent a boat explicitly offered by the rental company as “senza patente” (no licence required). The operator knows the specifications of its engine and whether that particular boat qualifies.
How far can you go?
A boating licence is required for recreational navigation beyond six nautical miles from the coast regardless of engine power. Your rental contract may impose a much smaller operating area.
Always follow the rental company's navigation boundaries. These can depend on the departure port, weather, sea conditions, protected areas and local regulations.
A 40 HP gommone is designed primarily for coastal exploration — moving between nearby beaches, coves and swimming spots — rather than long offshore crossings.
What is a gommone?
A gommone is the Italian term commonly used for a rigid inflatable boat. It is extremely popular in Sardinia because it is relatively easy to handle and ideal for reaching small bays that are difficult or impossible to access by road.
Most self-drive rental boats have a steering console rather than a tiller, so driving one feels closer to operating a small motorboat than a basic inflatable dinghy.
Where to rent one in Sardinia
Licence-free boat rentals are widely available in Sardinia's main coastal destinations. Popular departure areas include:
- Cala Gonone for the Gulf of Orosei and its famous coves;
- Villasimius for southeastern Sardinia;
- Alghero for the Riviera del Corallo and the Capo Caccia area;
- Cannigione and Palau for the northeast;
- Santa Teresa Gallura for the northern coast.
Do not assume that every destination or protected marine area can be entered freely. Some zones have navigation, anchoring or access restrictions.
What happens before departure?
If you have never driven a gommone, tell the rental operator. Before leaving, you should understand how to start and stop the engine, use the throttle, steer at low speed, operate the trim if fitted, anchor correctly and use the engine safety cut-off.
Also ask the operator to show you the permitted navigation area on a map and explain where you can safely anchor.
Check the weather, not just the sunshine
A sunny Sardinian morning does not automatically mean easy boating conditions. Wind can change the sea quickly, particularly around exposed headlands.
Check the marine forecast before departure and follow the rental company's advice. If the operator tells you conditions are unsuitable, postpone the trip.
Fuel is often extra
When comparing rental prices, check whether fuel is included. Many rentals are handed over with fuel and charged according to consumption when the boat is returned.
Also check the security deposit, cancellation policy, insurance conditions and what happens if weather prevents departure.
Do you need experience?
A licence-free boat does not mean a risk-free boat. First-time drivers should choose a calm day, stay within the operator's recommended area and avoid trying to cover too much coastline.
Slow down near swimmers, beaches, harbours and other boats, and never drink alcohol if you are responsible for driving.
Is a 40 HP boat enough for Sardinia?
For a relaxed day exploring a defined stretch of coastline, usually yes. The attraction is not speed: it is being able to stop for a swim, find a quieter cove and travel at your own pace.
If you want to cover long distances, visit more exposed waters or simply do not feel comfortable handling the boat yourself, renting a more powerful boat with a skipper is the better option.
The bottom line
You can absolutely enjoy a self-drive boat day in Sardinia without holding an Italian boating licence. Look specifically for a gommone senza patente offered by a reputable rental company, confirm the boat and engine are legally licence-free, and stay inside the operator's permitted navigation area.
The familiar “40 HP rule” is a useful shorthand, but the official threshold is 30 kW (40.8 CV) and Italian law also considers engine displacement. When in doubt, confirm the exact boat with the rental operator before booking.
