Methodology for Optimal Mast and Standing Rigging Selection of a Racing Yacht using AHP and FEM

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 racing yacht is even more important because the fact that such yachts are operated by professional crew that is capable to get out the maximum of the ship and its masts and rigging. So authors within this paper presents 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 first two phases and FEM analysis in the last one. The first phase includes identification of possible design solutions while the second one search for the best design configuration and determines the stability of the chosen solution. The third phase is used for load calculations, scantlings determination and final approval of the project variables. The proposed methodology is applied and tested on choosing a mast and standing rigging of the 40 foot racing yachts.
