We had the A Cat north american championships at our club last year and one of the guys who is a sales rep for Velocitek (anyone can be) had 6 boats run the units during racing. At the bar later he was able to run all six tracks at the same time showing the race as it eveolved. Very cool. For the GC08 you might want to approach Velocitek and see what you can work out. Maybe all boats carry some Velocitek advertising in trade for them supplying a certain number of units. Possibly work out a reduced price for regatta participants to purchase units. The possibilities are endless, or they might just say no. Of course when we did it the units were half of what they cost now. Oh well, worth a shot? Ed
