KM Yachtbuilders has turned the aluminium hull of Grey Shark, the tenth Bestevaer 53, at its Makkum shipyard. Witnessed by the owner and family, the milestone moves the explorer sailing yacht into its next construction phase and makes the proportions of the future vessel visible in a new way.
An Important Step Before the Yacht Is Complete
The Dutch builder’s announcement describes Grey Shark as a development based on Tethys, the Bestevaer 53 built for Belgian presenter and adventurer Tom Waes. The series is intended for owners interested in long-distance sailing, with individual yachts adapted to their plans and preferences.
The hull-turning milestone is a construction event, not a launch or delivery. Work continues at the yard, and the announcement does not provide a confirmed handover date.
For readers following a build, keeping these stages separate helps put progress in context. A recognisable hull is an important achievement, but it is not yet a yacht ready to begin its cruising programme.
From Fabrication to the Next Phase
“Turning a hull is always an important moment in the build.”
Oebele Woudstra, sales manager at KM Yachtbuilders, describes the operation in the yard’s announcement.
KM Yachtbuilders explains that the aluminium hull is fabricated upside down before being turned upright. This arrangement supports access during structural work; once the hull is upright, deck installation can follow.
Grey Shark’s owner and family attended the operation. The yard notes that this was their first opportunity to see the hull upright, with its lines and proportions clearly apparent.
That change in orientation has a straightforward emotional significance. Drawings and construction photographs demand imagination. A hull standing as it will sit in the water offers a more immediate sense of the vessel taking shape.
A Series With Room for Individual Decisions
The tenth hull indicates continuity for the Bestevaer 53 programme. It does not mean that ten owners have asked for precisely the same boat. The builder emphasises customisation within the established design.
For a prospective long-distance sailor, that raises a useful question: which choices should remain part of a familiar platform, and which need to reflect a particular cruising plan?
The answer may involve how the owner intends to live aboard, how many people will regularly sail together and which compromises they are prepared to accept. Those conversations belong alongside the excitement of a visible construction milestone. The hull is the beginning of a place to live and sail; the decisions that make it personal continue as the project develops.
