About SIREN

SIREN is a 73.5-metre custom displacement superyacht built by the renowned German shipyard Nobiskrug in 2008 and refitted in 2013, registered under the Cayman Islands flag. Designed inside and out by Newcruise, she carries a coherence of vision rarely achieved when exterior and interior studios diverge — every spatial decision, from hull profile to saloon furnishings, reflects a unified aesthetic sensibility. At this scale, SIREN occupies a tier of yachting where operational capability and guest comfort converge without compromise.

With accommodation for 12 guests across six cabins and an 18-strong professional crew, the staffing ratio is exceptionally generous, ensuring attentive and unobtrusive service throughout. She is well suited to groups who value privacy, seamless logistics, and the kind of unhurried pace that a large crew enables. Her charter regions span the Mediterranean in summer — Greece, Croatia, Sardinia, the Amalfi Coast, the French Riviera — and the Caribbean in winter, including the Bahamas, St Barts, Antigua, and the Virgin Islands. She is not ideally matched to guests seeking a compact, sporty platform or those chartering in a smaller group where the scale of the vessel might feel underused.

Her steel displacement hull and Newcruise design language suggest a vessel built for enduring quality rather than flash performance. A range of 7,300 nautical miles at a cruise speed of 14 knots affords genuine long-range capability, opening itinerary options that go well beyond the typical charter circuit. The presence of a helipad, beach club, elevator, and on-deck jacuzzi positions her among the more comprehensively equipped yachts of her size in the charter fleet.

Onboard, guests have access to a varied water sports inventory including jet-skis, waverunners, kayaks, wakeboarding, water-skiing, snorkelling, and a sailing dinghy. Stabilisers both underway and at anchor, combined with satellite communications and full air conditioning, ensure comfort in transit as well as at anchorage. The crew-to-guest ratio means every request is managed with a level of care that matches the vessel's physical stature as a charter yacht of the first order.

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 →
