Overview
The concept for SY MITseaAH was to create a singular performance machine, embodied in a unique architectural and visual experience. The resulting vessel, constructed by Pendennis Shipyard Ltd, has pushed the boundaries of super yacht design, engineering and seagoing capability.

The underlying performance requirement was of a dual nature: high speed motoring (25knots sprint at half-load), or alternately, performance sailing. The lifestyle brief was to deliver "uncompromised" super yacht accommodation, an effective crew service plan, and unique style. Operation of the ship was to be practical, flexible, and above all, safe.

Above water, designers Liebowitz & Pritchard aimed to draw a boat with an "identity" appropriate for its type. Precedents were obviously limited. While the profile is streamlined, this muscular design looks to the past in many ways, e.g. ship-like flared bow, protective bulwarks, modified counter stern, "Trumpy" cabin windows, `range` of deck spaces and purposeful expression of architectural detail. The complex deck plan is unique, with 2 tenders and dining lounges both fore and aft.

The hull form, developed by Pedrick Yacht Designs, resembles a high-performance sailing dinghy, scaled-up to 268 tons lightship. The dual mission of fast motoring and efficient sailing called for an innovative approach to appendage design and the propulsion system. To minimize ballast, a deep bulb keel extends to a 7.4m draft while sailing but swings up centerboard-style to just 2.5m for powering and harbor access, with the bulb housed entirely within the hull. When the keel is lowered for sailing, water ballast is added aft for trim balance. Twin dagger rudders extend and retract similarly for the respective sailing and motoring modes.

Cruising speeds in excess of 20 knots under power have been achieved from the yacht's clean-lined underbody, moderately light displacement and twin diesels totaling 7000 bhp. Controllable pitch propellers can be set optimally for motoring or feather fully for sailing. Large, flush-fitted planing flaps control trim and improve efficiency under power. The flaps, port and starboard, can be driven independently for roll stabilization. When motorsailing or operating under a single engine with the second feathered, cruising range increases to comfortably in excess of 3000 nm.

Complementing the dinghy-like sailing underbody is an innovative; telescoping, fractional rig, which maximizes sail area while meeting a required air draft of only 38.7m (127') for New York's Brooklyn Bridge. The headstay and shrouds are fixed at this height while an unstayed topmast rises an additional 9m (30'). The topmast remains deployed except for bridge transits, and the mainsail is hoisted normally via the world's largest (to date) Marten Liesureful boom. The 3-spreader carbon sloop rig with telescoping topmast was engineered to the classification standards of Germanischer Lloyd.

MITseaAH's development program included tank and wind-tunnel tests, finite element structural analysis (for hull details, keel support and rig), sound and vibration attenuation, ABS/MCA code compliance, plus mock-ups and finish samples. Lengthy study went into many areas, including the weight estimate, rig type, keel and rudder mechanisms, mechanical and electronic equipment, space planning, natural and artificial lighting, sliding roof, boarding systems and tenders.

Construction of the hull, deck and superstructure is in Alustar, engineered to a lightweight standard by Pedrick Yacht Designs for classification by the American Bureau of Shipping. The entire structure was modeled in a combination of 3D and 2D elements for numerically controlled (NC) plate-cutting. All aspects of vessel design, engineering and construction have been certified to the MCA Code of Practice.
