Now I know we are not all perfect, me especially, but the difference is I generally PAY ATTENTION all the time. Though there are not many people in this world who would own up to snagging their bow exposing their propeller and then cilling it in the same lock, and all that whilst going up! I am he. And to highlight there can be a danger even to long standing boaters I wrote about it somewhere here and and put a link on FaceBook.
In Napton a few years ago while delivering a boat. I saved a boat from sinking. If there is water coming through your front door and you are rolling a fag you are just not paying attention. Now say thank you, I just saved your arse, because I was paying attention! I shut the bottom gates, I opened the top gates to sort out the problem you were not paying attention to. I am sorry your gearbox destroyed itself, but that was nothing to do with me saving your arse!
Boating is fun! But if you dont pay attention it can be a disaster. I worry because I understand that boating is dangerous, others don't.
