As long as these electronic toys are available for everyone I dont see why we should continue banning them.
In fact a Tacktick Racemaster T070 (which almost everyone has now) costs the same a Rockbox or Nauteek unit.
Boats like Melges 24 are allowed to use stuff like this so why cant we?
I also dont believe it will turn sailing into a video game, in fact it might actually improve the overall quality of racing by keeping the fleets tigher together.
