About SEVEN S

SEVEN S is a 40.5-metre displacement motor yacht built by Mondo Marine in 2010 and refitted in 2014, registered under the Cayman Islands flag. The Italian yard's reputation for considered construction is evident in her aluminium hull, a material choice that balances structural rigidity with weight efficiency across a vessel of this size. The 2014 refit signals a commitment to sustained condition that distinguishes her from contemporaries of the same generation left unattended between charters.

As a charter yacht operating in Greece, SEVEN S is well-suited to small groups and families seeking a private, unhurried experience across the Aegean and Ionian. She accommodates ten guests across five cabins attended by a crew of eight — a ratio that affords a notably attentive level of service without the formality of larger vessels. She is not the right fit for guests expecting the scale or social energy of a superyacht north of 50 metres, nor for those prioritising high-speed passages; her displacement hull and cruise speed of 15 knots are calibrated for comfort and range, not velocity.

What sets SEVEN S apart within her class is her exceptional range of 3,200 nautical miles — one of the longer-range figures available in a 40-metre displacement hull, and a practical advantage for charterers who want to explore beyond the conventional Cyclades circuit without logistical compromise. The aluminium construction also contributes to a composed ride in open water, a quality that becomes meaningful on longer legs between island groups.

Onboard, SEVEN S is oriented around a balanced mix of outdoor activity and indoor comfort. The water sports programme is genuinely comprehensive for her size, with SEABOBs, a jet ski, wakeboarding equipment, and snorkelling gear making the platform well-suited to guests who want to spend the majority of each day in or on the water. A deck jacuzzi and BBQ support leisurely anchorage days, while a movie theatre and gym ensure that quieter evenings and early mornings have their own rhythm. At-anchor stabilisers meaningfully improve comfort during overnight stays in exposed positions, a practical feature that often goes underappreciated until conditions test it.

The provisional rating is based on available public data, reflecting acceptable standards across safety documentation, maintenance records, and operational protocols. As an independent authority, RightYacht provides owners and charterers with transparent, third-party evaluation — helping inform decisions beyond marketing materials alone.

About This Score

This is a provisional score based on publicly available data only. Unlike verified yachts, this listing lacks:

  • Independent on-board inspection
  • Crew qualification verification
  • Maintenance record audit
  • Safety equipment inspection

The actual safety profile may differ significantly.

Provisional scores are calculated from eight factors: vessel age, refit recency, classification society, flag state, crew-to-guest ratio, builder reputation, vessel size, and charter region coverage. All provisional scores are capped at 75/100. Learn how scores work →
