A couple of things I will add,
In the middle of YFT season, when you can see 100 odd boats over the mountain you cant expect to start a shark trail on the mountain and not have it crossed or disrupted by people that simply dont know better. its not a perfect world, especially on weekends.
Also, the fact that you own a 30+ foot boat, does not give you any authority or privileges over smaller vessels, like stewy said, no one owns the water and the smaller vessel has the same right to be there as a bigger vessel, be it cubing or trolling.
