Exterior
The striking exterior styling of the Arksen 85 was created by Humphreys Yacht Design. Finished in bare aluminium as standard, the hull and superstructure can optionally be painted or wrapped to suit personal requirements.
The selection of a super efficient Modeshift® hullform by Humphreys Yacht Design coupled with complex curvature on the hull has resulted in lower resistance and lower power requirement at long distance cruising speeds. This delivers optimum efficiency while also providing excellent seakeeping to maintain stability.
