TISG claims the article lacks technical rigor and cites unnamed sources, challenging the credibility of the allegations.
In January 2021, TISG acquired Perini Navi's assets through a bankruptcy auction, including its brand, archives, and real estate. TISG asserts it cannot be held responsible for any incidents related to Perini Navi vessels prior to this acquisition. The company is seeking to defend the Perini Navi brand’s reputation, a name synonymous with Italian excellence and advanced yacht design.
Key points of contention from TISG include:
Single-Mast Stability
The article suggested that the sailing yacht Bayesian’s single-mast design could compromise stability compared to the ketch rigging used by her sisterships. TISG clarified that while the stability curve differs from a ketch, the yacht fully meets the Maritime and Coastguard Agency (MCA) stability standards.
Expert Critique
The New Times cited multiple unnamed architects and engineers alleging design flaws. TISG counters that Holland, a prominent figure in naval design, created the Bayesian. They question the legitimacy of these “self-proclaimed designers,” urging transparency in expert attribution.
Doors and Hull Openings
The article implied that certain openings may compromise safety. TISG explained these are watertight and meet regulatory standards, only presenting risks if left open at significant heeling angles (above 30°), which the yacht’s monitoring systems are designed to prevent.
Handling in Adverse Weather
TISG argues that stability in rough conditions can be managed with proper operational procedures, such as maneuvering the bow into the wind. It also emphasized that water ingress only occurs through unclosed openings, and the yacht’s retractable keel enhances stability when deployed.
Ballast Placement
The Times cited concerns about the aft placement of the Bayesian's ballast. TISG clarified this was a calculated design choice to balance the forward-positioned mast, without compromising the yacht’s center of gravity or overall stability.
Sunken Deck and Buoyancy
While the Times suggested that the sunken deck reduced buoyancy, TISG contends this feature only affects buoyancy at extreme heel angles and does not impact regulatory stability requirements. The deck area is equipped with freeing ports for drainage.
Heel Angle and Flood Risk
TISG disputes claims that the Bayesian takes on water at angles below safety thresholds. They confirm that the Stability Booklet, MCA-approved, indicates an angle of 42.7° for significant water ingress, well within compliance.
Wind Impact and Heeling
According to TISG, during the night of the incident, gusts peaked briefly at 60 knots, resulting in a manageable heel angle of 18 degrees, far below the threshold for downflooding. Even under severe conditions, the yacht remained within safe operational limits.
TISG remains confident in the Bayesian's integrity, attributing any risks to procedural lapses rather than design flaws. They express trust in the ongoing investigation by Italian authorities to reveal the true cause of water ingress, reaffirming the yacht's stability and safety if correctly handled.
The Italian Sea Group (TISG) is a prominent entity in the luxury yachting industry, encompassing several distinguished brands. In addition to Perini Navi, it owns Admiral, known for its elegant and prestigious superyachts, Picchiotti and Tecnomar, celebrated for its sporty designs and high performance. TISG also operates NCA Refit, a division specializing in maintenance and refit services for yachts and mega yachts over 60 meters. This diverse portfolio reflects TISG's commitment to excellence and innovation in yacht construction and services.
