Who B4 suits
B4 provides a comfortable setting for a group of 12 guests, distributed across 6 cabins. Managed by a crew of 5, she is well-suited for those looking to enjoy the water, with kayaks, paddleboards, and inflatable watertoys provided for activity. On board, guests can relax with air conditioning and satellite TV, making her an appropriate choice for families or groups seeking a balanced pace during their time at sea.
At 31 m, she sits at a length similar to other yachts frequently found in Greece. Her capacity for 12 guests is the same as the alternatives in the area, and her 2005 build year remains similar to comparable vessels. For those monitoring the market, her weekly rate is also similar to what one might encounter elsewhere, ensuring she remains a practical consideration for those focused on standard charter specifications.
B4 operates in the East Mediterranean, West Mediterranean, Black Sea, Croatia, Cyprus, East Italy, Greece, Malta, Middle East, Montenegro, North East Africa, Turkey, Balearic Islands, and Spain throughout the year. While she is active from January through December, the best time to charter her is between April and October. Opting for May, June, September, or October allows for milder weather and quieter anchorages, while the peak months of July and August provide the warmth preferred by many travellers.

Cruising Greece: when to go and where to anchor
Best time
The charter season runs from April to October. Peak activity occurs in July and August, coinciding with high temperatures and the Meltemi wind in the Aegean. May, June, September, and October offer milder weather and lower traffic. The Ionian Sea generally experiences lighter winds than the Aegean, while the Saronic Gulf provides sheltered conditions. Early and late season bookings are recommended for quieter anchorages and more moderate sailing conditions.
Practical tips
- Most charters start at the Athens-area marinas (Alimos, Flisvos, Lavrio), about 30–50 minutes by car from Athens airport.
- Entry into Greek ports often requires stern-to mooring; ensure the crew is briefed on anchor deployment and line handling.
- Water supplies can be limited on smaller islands; monitor consumption and refill tanks at every opportunity in marinas.
Anchorages to know
- Lakka, PaxosA wide, horseshoe-shaped bay featuring a shallow sandy bottom, typically ranging from two to four metres in depth.
- Hydra HarbourA historic port on a vehicle-free island, requiring stern-to mooring in a tight, bustling harbour environment.
- Ormos Kleftiko, MilosA bay defined by white volcanic rock formations and sea caves, accessible only by boat.
- Gaios, PaxosA narrow, fjord-like inlet providing a sheltered natural harbour protected by the islet of Agios Nikolaos.
