Deadliest Catch is must DVR TV for me. I really enjoyed After The Catch. I feel connected to these guys because I served in the Bering 79-81 in the USCG. What you've seen is nothing compared to what happens out there.
I have a buddy I went thru boot with that was present at the Helo rescue of the guys that were washed overboard onto the ice. He was on the USCG Storis, but they could not get close enough to throw a line because of the ice and rocks.
We also fouled a prop, just like they did tonight, when we were leaving Kodiak. We ran over a submerged bouy that sea lions had busted. We put a smallboat over the side to cut it loose. While the guys in the smallboat were cutting free the line,our ship was drifting. The OOD, an Ensign, ordered to turn the screws to put us back in deep water. He did not inform the smallboat crew and suddenly the line they had been coiling into the lifeboat began spooling into the prop. The line wrapped around the ankle of the seaman that had been reeling it in and jerked him overboard straight towards the propellers. It was that guy's lucky day, believe it or not. The coxwain of the smallboat was our ship's 1st Lt. , CWO Hamm. This guy was old school thru and thru. In less than 5 seconds he threw the boat in gear, turned and chased down the guy being dragged underwater, reached out and cut the guy free with his knife.
The guy that was nearly killed quickly got bumped to the top of the school list of his choice.
