I-Sail Committee.
Next to the gps tracking I-Sail app there is now the I-Sail Committee specialised for race committees. Improve the accuracy of your race course and reduce the time to put all buoys into the water.
I-Sail Committee is a tool to simplify the work of race Committees by using real-time gps tracking on all committee ribs as well as on the committee vessel.
Use Navionics Nautical charts to see the local water depth at every buoy and make sure the ankers have enough line length
See the website to learn more about the behaviour of wind.
"Continued use of GPS running in the background can dramatically decrease battery life."
