I appreciate you sharing the listing, but I'm missing some crucial details to give you a proper expert opinion on Nadamas.

What I need: The charter base location isn't shown in your data, that's essential for me to assess travel logistics, sailing conditions, and value. I also don't have the weekly rate, so I can't comment on value for money. Without knowing the yacht's layout, engine type, or specific onboard kit, I'm guessing blind.

What stands out: A 2022 24-metre with five cabins and ten berths through a reputable operator like Istion is a solid mid-size option, and the zero deposit is genuinely attractive for charter clients.

Next step: Can you share the base location and weekly rate? Once I have those, I'll give you honest, detailed advice on whether Nadamas suits your group, how the pricing stacks up, and any trade-offs worth knowing about.

The marina & destination

Based at Agios Kosmas Marina, in Hellinikon - Athens, Greece. Nadamas is operated by Istion Luxury Yachts.

Why this is a great starting point

Agios Kosmas Marina sits on Athens's southern coast, offering quick access to the Saronic Gulf islands; week one typically takes you south to Hydra, Spetses, and Poros, with manageable day passages of 2-4 hours and consistent northerly winds. The shallow, protected waters suit both confident sailors and those building sea legs, while you can easily return to Athens mid-week if needed. Based near the city centre, the marina works well if you want cultural time ashore before or after your sailing.

Can Nadamas be rented with or without a skipper?

You can charter Nadamas bareboat (you skipper) if you hold the relevant sailing licence, or hire a professional skipper alongside the yacht. The choice is yours when you request the quote.

What sailing licence do I need to charter Nadamas?

Bareboat charter typically requires a recognised sailing licence (RYA Day Skipper, ICC, ASA, or equivalent) plus a VHF radio licence. The exact requirements depend on the country of charter — we confirm with the operator when you enquire.

What's included in the charter price?

The charter fee covers the yacht, standard equipment, and insurance for the dates booked. Tourist tax, transit log (final cleaning + bed linen), fuel, food, marina fees during the trip, and any optional extras (skipper, paddle board, etc.) are normally extra and paid at the base.

What additional costs should I expect at the base?

Typical mandatory extras are the transit log (often €200–€350), tourist tax (a small per-person-per-day fee), and a refundable security deposit (often €1,500–€5,000 depending on the yacht). Optional extras like a skipper, hostess, paddle board, or early check-in are listed on the quote.

How does the security deposit work?

The deposit is held by the operator at check-in (usually card pre-authorisation) and refunded after check-out if the yacht is returned without damage. Many operators offer a deposit-waiver insurance product that reduces the held amount in exchange for a smaller non-refundable premium.

Can I cancel my charter booking?

Cancellation terms vary by operator. Most allow cancellation with a full refund if requested more than 60–90 days before the start date, with progressive penalties closer to departure. Some operators offer a flexible-cancellation insurance product when you book.

Is the yacht insured?

Yes — every yacht is insured by the operator against damage and third-party liability. The insurance covers the yacht itself; personal effects and trip cancellation are not covered and are worth insuring separately.

What documents do I need to bring?

You'll need your passport, sailing licence (if chartering bareboat), VHF radio licence, and proof of payment. The operator will send a check-in form ahead of time covering crew details and any special requests.

What payment methods are accepted?

Charter fees are normally paid by bank transfer in advance (often a 50% deposit at booking, balance 30 days before charter). On-base extras are usually paid by card or in cash.
