the boat did not flip but it did get pulled under. You cant tell by the pictures but the waves where big and the nose of the boat would just dig in and down the boat would go.
At first they had a lot of rope out and the boat started to go down. After the fist time they shortened it up and I started taking pictures. It didn't seem to make any difference from what I could see.
If you look at the 5th and 6th picture that is the second time it started to get pulled under. If you look closely you can see passengers on the boat still. After the second time it went they got off into the rangers boat.
In the 9th picture it went under all the way and they lost a lot of stuff out of the boat.
10th picture the boat started to come back up again.
11th boat going back down
12th going deeper
After this the winds changed a bit and the waves where not as large. They took it into a small cove and pulled it up on shore as much as they could. The back end of the boat was underwater when at shore.
