ABSTRACT:
An outboard computer system which combines the outputs from onboard course, performance and wind measuring instruments to determine a sailing vessel's instantaneous rate of progress to windward when beating. This information is then used to produce audible and/or visual signals indicating to the crew when the optimal track and sail setting for the conditions has been attained, enabling them to beat optimally under the current ambient conditions. The system is also used to control automatically the settings of each of the sailing variables: rudder, main sheet, traveller, jib sheet, etc. in order to sail the vessel optimally when beating without the intervention of the helmsman or crew. A facility is also provided for recording the instantaneous rate of progress to windward in coincidence with any other variables of interest for the purpose of post evaluation and assessment of a variety of boat related equipment and procedures. The system also provides displays relating to wind history and wind prognosis. An optimal passage time automatic navigation system for sailing vessels is also provided.
