Multi-Objective Optimization of a Sailing Yacht Aluminum Mast
The optimal mast weight under specific structural strength requirements
The aim of this study was to reduce the weight of the world’s tallest aluminum mast for a new series of single mast sailing yachts manufactured by Perini Navi under the brand name Salute. The planned mast had a length of 140 to 168 feet (50 to 60 meters) high and needed to account for all the requirements related to structural instability, in order to ensure the best performance under operational conditions. As a result of our virtual optimization, the weight of the mast was reduced by around 20% with respect to the original specifications.
The objective was to find the optimal mast weight under specific structural strength requirements to avoid global and local buckling. The mast weight reduction and the parametric modeling allowed the evaluation of a correlated reduction of keel weight needed for counter balance. The keel and rudder lines were modified to improve the yacht’s stability in keeping with the higher center of gravity resulting from the tall mast.
