I've concluded that of my many opportunities for improvement, I'm especially weak on race strategy. The cure, I'm told, is experience: more time on the water. Sounds simple except I live where its a short season, and with 4 kids, family commitments frequently get in the way.

Therefore, I'm looking for a way to get as much value as possible from the beer-can and other semi-formal racing we do over the summer. One learning tool that seems especially valuable is race tracking. One can go back and replay a race and see where gains were made/lost, boat positioning paid off or didn't etc.

I know that Kattack has been used at some major events such as F18 Americas last October. Does someone know if this is an economical/practical solution when scaling to smaller races where only 3-4 competitors are present?

I came across another option called RaceQs. This seems like it might work for even as few as 2 boats, and uses the phone's accelerometers for things like heading, pitch, and roll in addition to usual GPS tracking. I've installed the app and it appears to function as advertised, although I won't have a chance to use it on-water for several months. Any thoughts? Anyone tried it?

Any other solutions out there?
