We were motoring up river when this Hunter 25 sailed up along side and passed us. Knowing the river, sailing (+/-) and the wind, I knew that he was going to gybe to starboard right in front of me. Also, I knew that the channel turned right and he was going to pass into the shallows. He was the stand-on vessel even though I was theoretically constrained by draft. (I only draft 30"). I backed off on the throttle and turned to starboard, about 20 feet astern of him. Sure enough, as soon as I had, he gybed to port and cut off my previous course. He never even glanced back. Prevention it everything. When investigations are conducted by the USCG, there is no right of way, only percentage of fault. If you can avoid it, do it. Give the right of way and wave a hearty hand. Are you in a hurry? I think not! You're in a sailboat.
