I've encountered 2 sunken jetboats in a logjam in the past 3 days. Apparently on the first one, all the passengers managed to get out on top of the jam and the captain wound up swimming, the second time, both captain and his wife (the single passenger) got flushed under and through. Both times the boats got flushed under and through in a seemingly innocent location with not nearly the water flow you'd expect needed to do this damage. If the captains reflexes had been quick enough, they both stated might have been able to actually safely beach their boats high and dry to the left, but they thought they'd just bounce off the logs and spin back upriver. Thank God everyone was wearing life preservers, and had matches and firestarter in their pfd pockets... they said it was miserable enough as it was waiting for help with a small fire... I did this same thing when I first started boating and its scary, with potential to kill someone. Both boats had seasoned captains... I'm cutting out this particular logjam tomorrow, (this is too close twice in a row) but in any case, please remember that being stuck high and dry is a very preferrable option to many things... (flushing through a log jam being one of them) Please don't let this happen to you and yours.
