Can I drive a boat without a licence?
Yes, under 6 HP. The leisure boating licence is only mandatory to drive a motorboat over 6 HP (i.e. 4.5 kW). Below that threshold — or for a sailboat, even with a small auxiliary motor ≤ 6 HP — no licence is required. It's the motor power, not the boat's size, that counts: a large, lightly powered sailboat can sail without a licence. At sea you need the coastal licence (up to 6 nautical miles from shelter) or offshore (beyond); on rivers and lakes, the "inland waters" option. Minimum age: 16.
📋 The rules
- Licence mandatory for a motor over 6 HP (4.5 kW)
- ≤ 6 HP or a sailboat: no licence required
- Sea: coastal licence (≤ 6 miles) or offshore (beyond)
- Inland water: "inland waters" option
- Minimum age: 16
🔓 Exceptions
- Sailboats: no licence, whatever the size (auxiliary motor ≤ 6 HP)
- Watercraft like jet-skis: licence required (powerful motor)
- Onboard safety gear remains mandatory depending on the navigation area
⚠️ Penalties & fines
Driving a motorboat over 6 HP without a licence is an offence: up to 1 year in prison and a €15,000 fine. Add the safety obligations (gear suited to the area, registration), whose breach is fineable. Even without a licence (≤ 6 HP), you must respect the navigation rules, speeds near the shore (5 knots within the 300 m band) and right of way.
