To the best of my knowledge, animals don't often use logic.  They use their instincts to survive and that's what they do.  So if a bear is about to destroy your kayak, for example, you're not going to be able to "talk" him out of it.

That's what Mary Maley found out the hard way.  Here's what she wrote on the youtube video:

During a solo kayak trip, intended to go from from Ketchikan, Alaska to Petersburg, Alask, a bear attacked my kayak. This incident occurred outside of a US Forest Service cabin in Berg Bay, Wrangell District, Alaska. I had just carried my tent, food, and all my gear into the cabin to dry while I went on a 4 mile hike that begins just behind the cabin. I heard something outside as I ate my lunch, and well, I never got to go on that hike. This video is taken 5 minutes after the attack began, he continued to gnaw on it for another 5 or 10 after the video ends. Shortly after the bear left and I drug the kayak back to the cabin door step. Then I swam to the S/V anchored in the bay. They did not have their radio on and I feared I would be stranded! The German flagged S/v Caledonia took me and my things to Wrangell where I am trying to repair my kayak now.

 

 

Everything was fine until she offered to spray the bear in the face.  Maybe next time you try being nice to the bear.  Maybe find out what its name is first.  Take the time to show the bear some respect and this won't happen again.  Then again....maybe that's just a bear and that's what bears do.
