I don't think anyone at our local knows, or use the out dated sail boat rules, even all the windsurfers that now kite, cause we don't sail slow turning big vessels that take minutes to turn/change direction etc.
But Im yet to ever see anyone have a direct collision in 10 years???
The boat sailors rules don't work in the surf, cause sail boats don't surf

,most of us here, well virtually all of us come from a surfing back ground and use the surf rules that work cause most are surfing waves, not cruising in a straight line wearing a sailors cap yelling PORT PORT STARBOARD at each other lol.
