Abstract
The racing yacht design process, except the hull and appendages, involves the selection of sails, rigging and mast. Proper selection and scantling calculations of the mast and standing rigging is of crucial importance as it is the backbone and connection of sail driving load transferred to the hull. Optimal selection within a racing yacht is even more important because of the fact that such yachts are operated by professional crews that are capable to get out the maximum of
the ship and its masts and rigging. Thus in this paper the authors present a novel methodology for the optimal selection of a mast and standing rigging based on the procedure in three main phases by using AHP method through the fi rst two phases and FEM analysis in the last one. The fi rst phase includes identifi cation of possible design solutions, while the second one searches for the best design confi guration and determines the stability of the chosen solution. The third phase is used for load calculations, scantlings determination, and fi nal approval of the project variables. The proposed methodology is applied and tested on the selection of mast and standing rigging of a 40-foot racing yacht.
