CRN delivers 70-metre Cerulean as full-custom buyers get a useful reality check

CRN has delivered the 70-metre superyacht Cerulean to her owner. Previously known as Project Thunderball, the yacht was handed over after trials and acceptance testing in Ancona. She was launched in June, but delivery is the point that matters most to a buyer: the moment when a design promise becomes an accepted yacht.

Cerulean has a steel hull, aluminium superstructure, 11-metre beam and around 1,100 GT of gross tonnage. Her arrangement includes an owner’s suite, five VIP cabins and accommodation for 15 crew in nine cabins. CRN handled the build and engineering, Vripack drew the exterior, preliminary naval architecture and general arrangement, and Nauta Design was responsible for the interiors and outdoor living areas. Y.CO acted as owner’s representative and project management team.

Why This Delivery Is More Than Another Length Figure

At this size, length alone says very little. The more useful question is whether the yacht has been shaped around the owner’s real use profile. CRN highlights continuity between exterior and interior geometry, and the yacht’s Energy Storage System. The system is designed to manage onboard power flows, support peak shaving and allow quiet operation at anchor. For an owner who spends time away from marinas, that is not brochure garnish; it affects comfort for guests, crew and neighbouring yachts.

The second signal is the importance of owner-side oversight. In a full-custom project, the owner’s representative is not a decorative role. That team watches acceptance, quality control, subcontractors and decisions that later affect handover, warranty and operating cost. The same lesson applies below 70 metres: the more individual the yacht, the less the buyer should leave to the commercial relationship with the yard alone.

Read The Engineering With The Contract

Cerulean is a reminder that full-custom should not begin with how many decks can be shown in a rendering. It should begin with owner profile, cruising grounds, energy at anchor, service access and project governance. As with contract-risk analysis in yacht building, an attractive product needs a controlled process behind it.

When buying or building a large yacht, an owner-side technical broker such as W Yachts should connect two worlds: the intended life on board and the list of items that must be checked, documented and accepted before handover.
