I've had it happen twice on the same day in AK near Montague Is.

First time it pinned my rod to the rail and I could nothing, it broke off rather quickly.


An hour or so later it was hooked again, this time it stayed near the boat for a bit and then started swimming off, we couldn't even come close to stopping it. The gear on the boat was very good, 140# braid on Penn Internationals (we were out for big fish), the Captain finally put on a heavy leather glove then climbed up on the transom, put his feet on the twin 200 Yamahas, cranked down on the drag and palmed the reel with the gloved hand. He was able to stop the line from going out but didn't really slow the fish down, it became very tight, started making creaking noises, then broke the 140# braid. The Captain said, "it happens, we don't know what they are, and we don't bother trying to fight them anymore."
