Yes — every boat on charter.boats is insured by its operator; we require it. The policy covers the vessel for fire, collision and third-party liability. You're only responsible for damage it doesn't cover, and that's capped at the security deposit.

Fuel isn't included — you return the tank full. This boat's ~15 HP engine burn roughly 1.2 L/h while motoring, so a typical week (about 3 h a day, ~21 h) works out to roughly 25 L ≈ €49 at €1.95/L — scale it to your own plans.

A Sportbootführerschee-See (SBF-See) is required for boats over 15 HP at sea; the ICC is recognised for visitors.
