Investigation of slamming loads using slam patches on a scale model of an Open 60' class yacht

Abstract

A model of an Open60’ class boat has been instrumented with slam patches in order to measure hydrodynamic forces acting on the bottom of the hull as a result of slamming. Drop tests and seakeeping tests have been performed to investigate the relative influence of different variables on the magnitude of slamming loads. Results are presented together with a discussion of the issues involved with this particular measurement technique.
