Perfect for groups. The Promise sleeps 12 across 6 cabins, making it ideal for families or friends wanting to share costs on a week-long sail. At roughly €350 per person per week, this is genuinely good value for a 15.4m yacht with proper cruising gear.

Well-equipped vessel. Water maker, generator, solar panels, and bow thruster mean you're comfortable and self-sufficient, no daily marina hops needed, and tight anchorages become manageable. This 2015 Sun Odyssey is a proven, seaworthy platform that won't surprise you with hidden gremlins.

Solid operator backing. MG Yachts has a perfect 5-star rating, though only two reviews, so track record is limited but promising. The €4000 deposit is reasonable for a boat this size.

One practical note: With 12 berths, cabin configuration matters, confirm whether you're getting six proper doubles or a mix of singles and bunks, as comfort varies hugely on group charters. You'll want to clarify the exact base location and flight connections from your home airport before booking, since the base isn't listed here.

The marina & destination

Based at Alimos Marina, in Athens, Greece. Promise is operated by MG Yachts.

Poseidonos Avenue

Why this is a great starting point

Alimos Marina sits just south of Athens, offering straightforward access to the Saronic Gulf's island-hopping routes; week one typically involves sailing to nearby Aegina, Poros, and Hydra, with predictable northerly winds in summer making these 15-30 nautical mile passages reliable for mixed-ability crews. The protected anchorages and short hops suit charter clients recovering from long-haul flights, while the marina's proximity to Athens airport (30 minutes by car) minimizes transfer time. Alimos itself has full facilities and is a logical base for exploring the sheltered Saronic islands before pushing further south toward the Peloponnese if conditions allow.

Can Promise be rented with or without a skipper?

You can charter Promise 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 Promise?

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.
