I have a buddy in Destin I used to go stay a few days with years ago. His next door neighbor and his wife were just taking a nice little cruise up the river when they hit a log. Threw them both out and the boat started circling in a tight loop. The wife got run over once, but came up ok. The second time, she went to brace against the boat and broke her wrist. Had to have surgery on it. Luckily, a boater came along and rammed the boat and deflected it to shore where it stopped.
They were lucky. Both could have been chopped liver.
I can attest to boat props danger. I have a scar from 20 stitches in my foot from a prop that was not even turning.....

. We had been out skiing all day and running in to a few sand bars here and there. I could have shaved with that thing. Went to climb the ladder, felt something brush my foot, and when I put my foot on the step, it opened up a gusher....Closest I ever came to fainting that day. I had to lay on the dock for a little while....
He had a buddy that was a doctor. Called him on a sunday eve. We wrapped it up, went out to eat, and then the doc met us at the office and stitched me up. Ther was no hurry because of pain, since I had been taking pain killers all day

The more I know about something, the more I know that I did not know as much as I thought I knew that I knew.
