What's included — and what isn't
The first thing to establish is exactly what the base fee covers. It almost always includes the boat, basic equipment, and insurance. It almost never includes fuel, marina fees away from base, the end-of-charter clean, tourist taxes, or extras like a skipper, dinghy outboard, or wifi. Read the inclusions list line by line — the gap between 'charter fee' and 'total cost' can be substantial.
The security deposit
You'll lodge a security deposit — often €1,500–€4,000 — held against damage. Understand how it's taken (card hold vs cash), what it covers, and how quickly it's returned. This is the single biggest financial risk in a charter, which is why the deposit waiver matters.

The deposit waiver (and why to consider it)
For an extra fee — typically 5–15% of the charter price — you can buy a damage waiver that reduces or eliminates your liability. It's effectively an insurance excess reduction. For most charterers it's worth it: it converts a frightening multi-thousand deposit into a fixed, modest cost and removes the post-charter anxiety over every scratch.
Cancellation and refund terms
Cancellation clauses are where contracts bite hardest. Most charters become non-refundable as the date approaches — often 100% within 30–60 days. Check the schedule carefully and strongly consider separate travel insurance that covers charter cancellation. Don't rely on the charter company's goodwill.
Check-in and check-out terms
The contract specifies handover and return times — and penalties for a late return. Note the required fuel state on return (usually 'full to full'), the cleaning expectations, and the time you must be back at base. Returning the evening before is standard so the boat can be inspected and turned around.
Red flags to watch for
Be wary of vague inclusions, deposits held in cash with no clear return process, no mention of insurance, or pressure to sign without time to read. A reputable charter company gives you the contract in advance, answers questions plainly, and has clear, written terms. If something is ambiguous, get the clarification in writing before you pay.
