70m CRN Cerulean Delivered After Sea Trials

Handover after trials in Ancona

CRN has delivered its 70-metre custom superyacht Cerulean to her owner after completing the shipyard's tests and sea trials in Ancona, Italy. The vessel was previously known as Project Thunderball during construction, making the handover a new milestone rather than a repeat of earlier project updates.

The Ferretti Group yard confirmed the delivery on 16 September 2026 and described Cerulean as a fully bespoke displacement yacht. She measures 11 metres across the beam and has a reported gross tonnage of 1,100 GT, according to CRN's release.

Vripack, Nauta and the owner's team

Vripack Yacht Design developed the exterior, preliminary naval architecture and general arrangement. Nauta Design designed the interiors and outdoor living areas, with a brief emphasising movement and continuity between indoor and outdoor spaces.

Y.CO represented the owner and managed the project throughout construction, including technical oversight and acceptance work. CRN handled the build and its associated engineering, with the yard and design studios collaborating on the customised specifications.

Accommodation across four decks

The yacht accommodates 12 guests in an owner's suite and five VIP cabins, while nine crew cabins provide berths for 15 crew members. CRN describes a long bow and a profile drawing on sailing-yacht forms, with proportions echoed through the interior spaces.

These figures put Cerulean firmly in the large custom-yacht sector and clarify her configuration following earlier reports about Project Thunderball. The delivery announcement does not disclose a sale price, so there is no verified transaction value to report.

Battery-supported onboard operation

An onboard energy storage system manages power flows according to operating requirements and supports peak shaving. According to CRN, it can also enable quieter operation while the yacht is at anchor and contribute to lower fuel consumption.

The yard has not published independently tested fuel-saving figures in this release, and the claimed benefits should therefore be read as the builder's description rather than a quantified performance result. The completed delivery now moves Cerulean beyond the construction and launch stages of her project history.
