The Sailing GPS is unique in realizing that sailboats often zig-zag to their destination, which affects the distance and travel time.  If standard GPS chartplotters don't know how far your tacking route is, how can they calculate the ETA correctly?  Fortunately, The Sailing GPS solves this problem.  It accounts for sailboat tacking when calculating optimal routes, distances and Tacking Time to Destination.
