Legal frame
Governing: D.Lgs. 171/2005 (Codice della nautica da diporto) arts 3, 27 and 39. Builds on: nothing — start here.
Three words that decide everything
Before a rental desk asks for your licence, Italian law has already sorted the boat. The Codice della nautica da diporto (the pleasure-boating code, D.Lgs. 171/2005) uses these terms, and every operator, ordinance and fine refers back to them.
| Italian term | What it means | Typical rental |
|---|---|---|
| Natante da diporto | Rowing unit, or hull 10 m or less (ISO 8666), jet skis excluded | Gozzo, small RIB, 5–6 m open boat |
| Imbarcazione da diporto | Hull over 10 m, up to 24 m | Sailing yacht or motor cruiser on a weekly charter |
| Moto d'acqua (jet ski) | Hull under 4 m, water-jet drive, riders sit, stand or kneel on the hull | Jet ski, personal watercraft |
Anything over 24 m is a nave da diporto and needs a professional-level licence; it is outside this guide.
When a licence is required
Art. 39 makes a patente nautica (boating licence) compulsory for units up to 24 m in three situations:
- Beyond 6 nautical miles from the coast — motor or sail, whatever the engine.
- On any jet ski, whatever its power (Lesson 1.3).
- Within 6 nm, if the engine is over 30 kW / 40.8 CV or over the displacement limits below.
| Engine type | Licence above |
|---|---|
| Two-stroke, carburettor | 750 cc |
| Two-stroke, injection | 900 cc |
| Four-stroke outboard | 1,000 cc |
| Four-stroke inboard | 1,300 cc |
| Diesel, not supercharged | 2,000 cc |
| Diesel, supercharged | 1,300 cc |
Power and displacement both count: a boat that exceeds either needs a licence.
The licence-free boat
Stay inside 6 nm with an engine below the limits and no licence is needed. The law still sets minimum ages for whoever is in command (art. 39(3)):
- 16 for a natante — the usual licence-free rental;
- 18 for an imbarcazione;
- 14 for a sailing natante with more than 4 m² of sail, or a rowing boat going beyond 1 nm.
A 15-year-old at the helm of a licence-free natante is committing an offence (art. 53(5): €65–665), even with a parent sitting beside them.
How far you may go
Distance limits come from the boat as well as the licence (art. 27):
- Natanti without CE marking: within 6 nm (12 nm only if type-approved for it).
- CE-marked natanti: within their design category, never beyond 12 nm.
- Pedalos, canoes, paddleboards, sail up to 4 m²: within 1 nm.
- Jet skis: within 1 nm.
In practice a licence-free rental is a natante of 40 CV or less that must stay within 6 nm, and the operator will usually set a tighter area in the briefing.
TIP — Read the engine plate The cowling says "40" but the documents say what counts. Ask to see the engine's power declaration: if it shows more than 30 kW / 40.8 CV, you need a licence whatever the desk tells you.
CAUTION — Licence-free is not rule-free Speed limits, bathing zones and alcohol limits apply to you exactly as to a licence holder. The fines are the same, and in some cases heavier (Lesson 4.1).
Readers who have rented in Spain or France will find the logic familiar but the numbers different; see Renting a Boat or Jet Ski in the Balearics and Renting a Boat or Jet Ski in France for comparison.
