SY Thalassa – Reliable, well-maintained and ideal for authentic Ionian cruising

SY Thalassa is a privately owned Beneteau Oceanis 423 Clipper (2006, refitted 2024/25, further upgraded 2026) in excellent technical and visual condition, based in Preveza.
The yacht has been continuously maintained and upgraded with great attention to detail, making it a reliable and comfortable choice for families, couples or experienced crews looking for a safe and authentic sailing experience.
With 4 cabins and 3 bathrooms, Thalassa offers a well-balanced combination of space, sailing performance and onboard comfort.

-Balanced sailing performance with comfortable interior layout
-Warm and well-kept onboard atmosphere (refurbished woodwork)

Location & cruising area
The yacht is based in Preveza, at the entrance of the Ambracian Gulf – one of the best starting points for Ionian sailing.
From here, popular routes include:
- Southbound: Lefkada, Meganisi, Ithaca, Kefalonia
- Northbound: Parga, Paxos, Corfu
Short distances, protected waters and well-developed infrastructure make this area ideal for both relaxed and active itineraries.

Access
- Aktion (Preveza) Airport: only a few kilometres away (direct flights May–October)
- Athens: approx. 3.5 hours by car

Bow Thruster (2026), Full Refit (2024/25): Rigging, Outboard Engine, Anchor & Anchor Chain, Throttle Control, Gas Stove, Flexiteak, Upholstery, Batteries, Dinghy; plus Sails & Instruments (2019).

Solid Mid-Range Cruiser The Oceanis 423 is a proven, comfortable cruising yacht that suits couples and small families wanting to explore Greek waters without breaking the bank. At 13.1 metres with four cabins sleeping eight, it offers genuine flexibility for mixed groups, though you'll want to manage expectations around personal space on longer trips.

Well-Equipped for Comfort You're getting thoughtful extras here: electric winches, autopilot, bow thruster, and solar panels mean less sweat and more relaxation underway. The teak cockpit, bimini, and sprayhood suggest this boat was maintained with an eye toward cruiser comfort rather than racing pedigree. Snorkeling gear included is a nice touch for Greek island hopping.

Excellent Value Proposition At €2,115 per week with a modest €2,000 deposit, this represents genuine mid-season value for a four-cabin cruiser in Greece. You're chartering with GreeceXperience (5/5 rating), and that operator knowledge matters when you're flying in from abroad and need reliable local support and clear handover procedures.

Age Is the Honest Note Built in 2006, this boat is nearly 20 years old, not ancient, but worth asking about the condition of systems like the fridge, plumbing, and seals. Request a recent survey report or specific maintenance details on the engine and through-hulls before committing, especially if you're planning a

The marina & destination

Based at Preveza Main Port, in Preveza, Greece. Thalassa is operated by GreeceXperience.

Why this is a great starting point

Preveza Main Port sits at the mouth of the Ambracian Gulf, making it an ideal launch point for exploring the Ionian Islands to the west and the protected waters of the gulf itself to the east. Week 1 typically involves sailing north toward Lefkada and Meganisi or south along the mainland coast to Zakynthos, with reliable northwesterly winds (Maestro) providing consistent sailing conditions. The marina offers good provisioning and is close enough to Athens airport for convenient transfers, though expect some swell in the outer Ionian during summer and plan accordingly for the narrow entrance channel.

Can Thalassa be rented with or without a skipper?

You can charter Thalassa 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 Thalassa?

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.
