thanks jeff. so by that defination a confused sea of wave/swells of equal size would not be considered a rogue wave. example being the picture above not being a rogue wave. and beny's example of and outsider/sneeker would/could be. question then in a confused sea when the sea's collide and the insuing wave jacks up upon collision. can you measure that? or is that just a by product. the reason i ask these stupid questions. I've had many beer/driven arguments/friendly discussions on this. and I've been told i'm flat wrong. but Jeff's definition is what i thought a rogue wave was. "there's no clear definition of what a rogue wave is" "dude it was triple overhead" "boy, you shoulda been here yesterday"
