It wasn't a problem in flat water and 15, but I have a feeling when the S*&t really hits the fan two people swimming for the side of the boat could let the thing get away.
I can testify to that - two of my friends flipped a Tiger and lost contact with the boat while manouvering around it to get into a righting position. The Tiger threw a pretty reasonable wake as it blew off downwind. We rescued the two drowned rats and delivered them back to the boat - but if we weren't around it could have been more serious....my first priority now is to keep contact with the boat at all times.
