Jean-Nicolas,
I am not trying to douse flames with gasoline. I do not question the way YOU handled the situation. And of course CJ did an amazing job hooking the rope to the pinned boat. But in the case of the recovery of your pinned boat, do not forget what ACTUALLY happened.
(1) Paul and myself were telling you all as soon as we saw the situation to pull the boat from upstream, the way it got there in the first place. Reply from CJ et al.? That it would mean pulling agaisnt the current, thus impossible to free the boat that way. The current was not that strong in fact, they were wrong, and this was made very clear later.
(2) Instead of pulling it from upstream, a 6:1 (if I remember correctly) mechanical advantage system was set up from ACROSS the river, using pulleys and at least three strong guys, to pull the stern in a direction almost perpendicular to the axis of the boat. They were not able to free the boat this way. I'm willing to bet, however, that instead this did a good job wrapping it around the rock. The damage to the boat, as seen on the last photo below, is consistent with this hypothesis. When it was clear that this method was not successful, it took more than 15 minutes to release the tension in the ropes. That's a lot of force--can anyone in all honesty say that the river current ONLY was responsible for the destruction of the boat, as in "The boat was bent way before we even anchored it"? Is this known for sure?
(3) After the tension was released in the ropes from across the river, it took only a few minutes for Paul, Alex and myself to use the other rope to set up a 3:1 mechanical advantage system from upstream with only carabiners, no pulleys, and pull the boat free.
These are the important parts, to set the record straight. There are a lot of photos documenting the event, I'm not distorting things. I may have been a bit harsh when writing "stubborn young people bent on ignoring the advice of more experienced paddlers.", but no offence was intended--just a statement of the facts. Sincerely,
