SailChecker Expert View

Perfect for families This 2025 Bali 4.2 catamaran suits families or small groups wanting comfort without complexity , four cabins sleep eight, and the wide, stable platform means less seasickness and easier sailing for mixed ability crews. The generous outdoor living space with a barbecue grill and convertible table makes entertaining and dining al fresco genuinely enjoyable.

Smart modern touches You're getting a brand-new build with air conditioning, autopilot, and electric winches that take the physical grind out of sailing, plus a surprisingly sociable cockpit setup with speakers and cushions. The lazy jack (which simplifies mainsail handling) and solid generator power are genuinely thoughtful inclusions at this price point.

Strong value proposition At €4,520 per week from SeaStar Sailing , a highly-rated operator with 4.9 stars , this feels fair for a modern four-cabin cat with all the comfort kit already fitted. The €3,500 deposit is reasonable too, and you're chartering from an established, trusted company.

One realistic note The Bali 4.2 is a catamaran designed for laid-back cruising rather than spirited sailing, so if your crew craves responsive handling and tight manoeuvres, this won't thrill you. Otherwise, for a relaxed week with good company and minimal fuss, this boat delivers.

The marina & destination

Based at Alimos Marina, in Athens, Greece. Swell is operated by SeaStar Sailing.

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.

Frequently asked questions
Can Swell be rented with or without a skipper?
You can charter Swell 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 Swell?
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.
