I notice in Wakeboarding Mag that there are a lot of pictures with one guy driving and one guy riding... aren't we supposed to have three so that one can flag? I would love to go out with just two but I don't think it's legal. At least not in CA.
same goes for VA, one in the boat with a mirror. Actually, I'm not even sure if that's necessary, because I've never been pulled over. As long as the rider has a CGA vest on, it's legal in VA for there to be only the rider and the driver.
In Alabama you need a spotter if you don't have a mirror. We ride with just two sometimes during the week when nobody else is out or for an early morning sesh. It is very rare though. We usually have at least three.
In Tn as long as you have a mirror you dont need a second person in the boat. Another interesting fact is as long as you have a CGA vest on board, the rider is able to wear non-cga without a second person on board. I just thought it was kinda odd, but TVA officer pointed it out to me in the manuals that it was legal...
