For some of us gps would be a huge benefit during competition.
Pete, this is just like anything else. If it is allowed, the guys who already know how to sail will have an even larger advantage as they will be both better equiped to not be distracted and will know better how to interpret what they are seeing.
I see this as an issue where we just add to the skills gap that is already a big issue in getting more people involved. New guys now have to buy a boat, gear, spend money to travel, and oh yeh now to be competitive you just have to have one of these new boxes to tell you what to do.
Where is there any advantage and how does this make racing better?
