When do you need a Nautical Licence ?
For operation of a pleasure or other craft more than six miles from the coast.
For water-skiing, regardless of the engine power of the towing vessel.
To drive jet-skis.
If the vessel’s engine is over 40.8 hp (30 kW) in power, or 2,000 cc in displacement (750 cc for Diesel), or the engine is a two-stroke outboard.
Not all European countries issue Nautical Licences. In Italy it is compulsory.
