Aims of the work were the design, calibration and installation of an instrumented mast and standing rigging system on a 420 sailboat for the dynamic measurement of structural loads for innovative design of mast, hull and sails. A measurement system for both laboratory and sailing tests was developed.

Data acquired may also be used to study the mast stiffness to improve sail design: displacement measurements are difficult to accomplish, so an indirect structural approach can be adopted to reconstruct the deflection line of the mast.

Abstract

Aims of the work were the design, calibration and installation of an instrumented mast and standing rigging system on a 420 sailboat for the dynamic measurement of structural loads for innovative design of mast, hull and sails. A measurement system for both laboratory and sailing tests was developed. The resulting bending moment diagrams were plotted along the mast and shall allow designers to improve the mast’s cross section profile or material selection. Moreover, the accurate knowledge of loads acting on the standing rigging and on the mast-step will support the optimized design of the boat shell. Data acquired may also be used to study the mast stiffness to improve sail design: displacement measurements are difficult to accomplish, so an indirect structural approach can be adopted to reconstruct the deflection line of the mast. Some of the carried out measurement systems can be directly used in other dinghies, while the adopted methodology is generic and can be applied to many sailboats for various innovation studies.
