- The page says course changes update both the route and the course sheet while racing.
Field notes
The described workflow begins with a chart containing the area's race marks: sailors select them in sequence, set each rounding direction, and can add an uncharted mark with a long press. ProSail says the display advances to the next mark with bearing, distance, and ETA, and that course changes update the course sheet as well as the route. The page also describes offline use with an iPhone or cellular iPad GPS.
