so here is the video from Ham. My camera was mounted on the bimini in the front right corner. I had an ocelot, 120 yeti, kitchen box, and my wife. the ocelot was getting hung up on pretty much everything until Moose Creek.
if you watch the video, the path I was trying to take was straight ahead at 1:01.
I hit a submerged rock that spun my cat sideways and I got hung up right before it, at 1:13
I jumped into the center of my cat floor and tried to lift the cat over the rock but put myself in a position I could recover quickly and get the boat down the original chute.
2:28 the boat starts to move
2:31 you can see the submerged rock and hear my wife say "oh my god" as I slipped and got pulled under the boat (still hanging by my hands on the frame)
2:33 - initial collision with the rock on the pro-lock --- pushed off the rock to get the boat to move it once I was back onboard. lots of scraping of the oars and the tower
2:50 - done pushing off the rock
