Objectives

This course shows the mecanisms of wind propulsion which is mainly used in the nautical industry for leisure and racing yachts. A renewal of wind propulsion technologies for commercial shipping has also been noticed for the last few years in order to reduce emission of polluting gas.

This course gives the methods in use for the technical design of sailing yachts and the main factors which influence performance, including examples from practical projects. The effects of meteorological aspects, practical and engineering constraints are also addressed.
