Humphreys Yacht Design has unveiled the H50EXP, a 50-metre explorer yacht developed with Mark Whiteley Design and Occam Marine.
The sub-500GT project is intended for extended cruising, with scope to adapt its accommodation, deck spaces and equipment capacity to individual owners’ requirements.
The design targets a top speed of 18 knots and a range exceeding 5,000 nautical miles at 12 knots.
The yacht has been designed for self-sufficiency and extended cruising with Humphreys stating that the combination of long-range efficiency and higher cruising speeds would give owners greater flexibility in passage planning, weather windows and itineraries.
Humphreys is responsible for naval architecture and exterior design, while Mark Whiteley Design is developing the interiors.
Occam Marine is providing technical development and build consultancy. The partners have focused on space planning, systems integration and buildability to support progression towards construction.
Technical platform
The technical platform draws on Humphreys’ experience with explorer yachts, including the 50-metre CANOA and designs for the Arksen Explorer Series.
The company says hydrodynamic development, model testing and sea trials from that work have informed the H50EXP’s engineering foundation.
Interior proposals combine oak, leather and sculptural elements in a contemporary, practical scheme.
The arrangement and specification can be tailored alongside the aft deck and lazarette, allowing the yacht to serve either long-range leisure cruising or a more expedition-focused role.
Options include configurations for tenders, vehicles, watercraft and specialist equipment, with crane arrangements matched to the intended inventory.
Adaptable interior
Enhanced deck loading and equipment-handling capability can be incorporated where required.
The balance between guest accommodation, crew provision and technical spaces is also adaptable, including for a support-focused operating profile.
The announcement highlights ‘particular emphasis on technical feasibility, buildability and efficient progression into construction’.
Initial discussions with selected shipyards are under way to establish indicative build costs and support further development.
