ARREDOMAR MORGANA 72

Arredomar Morgana 72

Sometimes amidst the many trials of many boats, we are overcome by an irresistible emotion: the emotion of silently "flying" on the water, heeled to the gravity's limit in the cockpit, the emotion of climbing to the top of the mast, face to the wind, and "experience" the wind's power caught in the sails of the magnificent creature, from the unusual perspective of the deformed mast and the top spreader close to one's feet.

A necessary introduction, when speaking of the Morgana 72, the "one-off" sloop built by Sergio and Renzo Marchìs Arredomar, a manufacturer that since 1927 (foundation year) has offered prestige boats to the yachting world. It is not difficult to foresee that the Morgana will be yet another one; considering that she was commissioned free of any limitations both to form or dimension, and that her primary objective is to ensure comfort and performance, the design evolved on pure and essential lines. The outcome - an exclusive boat destined to maintain a subtle balance between a streamlined hull, dimensions, open space on deck and an elegant layout of interior - surely could not have been compromised by measuring restrictions that would have inevitably affected the hull. Morgana will therefore race under the International Measurement System (IMS), but will still be able to take part in IOR races with a rating below 70'.

These are the main characteristic of Morgana 72', whose design was developed, in search of truly superior performance and speed, optimising hydrodynamics and structure. A fractional, high aspect ratio sail plan and a minimum area keel layout were associated to a keel with a high prismatic coefficient, rounded sections and a minimum wetted surface. The sandwich structure in kevlar and "R" glass impregnated with epoxy resin and the interior, entirely constructed with sandwich panels of teak and termanto, allow for a displacement below 28 tons, with a load percentage similar to that of a racing maxi.

All this to the advantage of low radius and reduced pitching.

The sail plan was engineered for great operational simplicity, so that the boat can be sailed with a small crew. This is made possible by a fully-battened mainsail, a furling genoa and the predisposition for a self-tacking stay-sail, fitted on an extremely light but reliable mast thanks to the swept spreaders. Manoeuvring is assisted by hydraulic and manual controlled winches. Decks and interior design enhance the boat's elegance. Cockpits have generous volume, the deck is low and harmonious with large sidedecks, and the running rigging is laid out so as to leave the deck uncluttered without forsaking the ease of movement. Below decks, besides the evident care in the choice of materials and craftsmanship of the interior, special attention has been paid in the cabin layout so as to guarantee privacy and a high level of comfort.

Three double berths cabins with independent heads and showers, and a large saloon with a cocktail cabinet and a chart table, make up the owner's living quarters. At the bow lies the galley, the crew cabin, the sail locker with the work bench and an independent hatch for the crew.

System and auxiliary services are also at top level: generator, desalinating plant, fridge, air conditioning and a hydraulic control panel for winches and the anchor windlass. The mechanical equipment is located in two easily accessible areas of the boat: in the engine box (for the main systems: engine, generator, hydraulic groups) and in a locker, for the secondary systems. The attention placed by the designer on all the aesthetic and technical aspects make the Morgana 72' a technologically advanced yacht.
