About 10 years ago I had a guest hook a shark on a 16oz lead head jig on a bottom rod with 80 Tuff-line. As soon as he hooked it it took off on a full speed run that my kicker couldn't keep up with, I quickly gave up on that and fired up the main. We chased it a long ways for about 10 minutes then it seemed to slow down and we got some of our line back. As soon as we started really pulling on it and tried getting it to start coming up it took off again, this happened 3 or 4 times and went on for about an hour. Finally we got over it and started getting it to come up, foot by foot, very slowly. About half way up from 370' of water the reel seized up and I hand-lined it the rest of the way, took about an hour. It ended up being an 9'-10' shark which I'm assuming was a salmon shark, had never seen 1 before or since.
The jig was in its mouth but the tuff-line was wrapped around its tail, fought like hell for over an hour then I think we drowned it pulling it up backwards.
Over 22 seasons up there I have hooked a lot of big fish, 300+lbs halibut, and skates but none of them compared to the runs this shark took. Only other things I could compare it to were porpoise, sealions, and humpbacks, hooked a few of those (briefly) over the years.
