OnboardAssistant is a handy little tool for yacht racing which will complement your onboard electronics and let you get rid of wet notes. It will let you ping sail changes, race times, changes in boat configuration, incidents, performance comments and any other important user-defined event which is not captured directly by your electronics. It also lets you take pictures, record audio and video while you are out on the water. Once your sailing session is complete you can review and update your notes and upload it all to the cloud. Once in the cloud, the data can be accessed by a number of thrid party tools such as SailingPerformance's RaceReplay. All your data will then be automatically be loaded and synchronized, ready to be analyzed! Terms of use available at: https://www.advancedsailingperformance.com/oba-terms-service.html
