An Open 50' for Adriatic races.

The boat has to be design for in and offshore races in the Adriatic Sea; the length is been chosen based on the local regulations and for a compromise between light and strong wind characteristics. A canting keel system will be developed to increase the stability in strong winds conditions keeping the displacement not very high. For the use of the canting keel system a front dagger board is necessary to increase the side force of the boat; to maximize the boat performances is been decide to use two asymmetric dagger boards, fore the mast, one in each side. The study of their Lift and Drag coefficient is been taking into account to optimize their performances; various NACA profile has been take in consideration. The boat is design as fully racing boat so all the criteria are focalized for its functionality, maneuvers and simplicity of the deck lay out; a large open cockpit is required for an easy crew disposition during maneuvers. A height of 1.85 m is required in the inside of the coach roof for an easier crew liability and to keep a good relationship between the length of the boat and its height. To make the boat faster in light-wind conditions, high SA/Δ and SA/WSA ratios have to be reach. The mast design will focus on the performances in light wind conditions with the forestay height on 9/10 of the mast length with the possibility to use a masthead asymmetrical spinnaker and a “code-zero”. Two runners and backstay for each sides and shrouds with few degrees angle of sweptback spreader will support the mast. The hull will be built in E-Glass composite material; for all the appendages carbon laminates will be use as more sensible in term of performances. The boat will be built as “one off” design with a male mould
