A twin rudder configuration was chosen for efficiency and high-controllability of the wide, powerful hull needed carry a large downwind sail plan and maximise benefit from sail stacking and crew weight. Extensive CFD research was carried out by Kernan Yacht Design in conjunction with Egan Associates to optimise the hull form for twin rudder configuration and encourage the best transition to planing. This extensive research program has resulted in a very well balanced hull form at all heel angles, which transitions easily to planing and has the ideal tendency to lift the bow when pressed hard.Primary shell and framing structure is post-cured pre-preg Carbon/ Nomex Honeycomb, with Corecell M-Foam employed in the heavily loaded forward slamming areas. The engineering directive was to produce a no-compromise structure capable of protracted offshore abuse at the lightest possible weight, and the team at Westerly Marine executed the build flawlessly.Appendages were developed in conjunction with the Aerospace department at Cal State Long Beach. The keel fin is a high strength stainless steel weldment, post machined to proprietary foil shapes within a high tolerance. Rudders posts are pre-preg carbon custom shaped to match the blade which is cnc machined to exacting tolerance. Rudder bearings and steering system is JP3, with a unique tie-rod system that allows easy adjustment of toe-in/toe-out and features two settings to adjust helm pressure.To achieve the most versatitlity in the deck layout, all lines including halyards are lead to deck level and can be cross-lead to multiple winches. This allows for the versatility of using the primary pedestal system to hoist as well as trim sails. The ultra-clean above deck layout is facilitated by control lines lead below deck in an innovative system which insures that it stays dry below-decks. Thus, control of sail handling systems is as effortless as a med-cup TP52, without the associated water ingress which is such a nuisance for offshore sailing.The interior arrangement features generous owner’s berths port and starboard with ample storage lockers and privacy curtains forward of the companionway, with pipe berths for 4 additional crew / side aft. The galley incorporates a large icebox, propane stove, sink and microwave oven. Forward of the main bulkhead on centerline is an enclosed head with shower. This configuration allows for sails to be stacked and moved port or starboard, and facilitates a spinnaker packing system running for/aft the length of the yacht.
