::) On a trip down the Basswood River with a novice kayaker, we were lining down rapids instead of portaging.  She was having a hard time lining her boat and walking along the ledgerocks and finally dropped her rope.  We weren't at the next rapids yet so I, being still in my boat, chased it down and got the rope to her.  Not, unfortunately, before I was caught in the tow of water that would pull me down over the drop in the rapids.  Quickly deciding I had no alternative I paddled like mad to gain speed and went over the rapids, with no prior preparation.  Luckily it was a low water time of year so it wasn't too wild.  I bottomed out on one rock, but not hard enough to hurt my kayak and made it through upright and mostly dry  :-[.
