How big was the sub you caught? lol
We were fishing in Lake Michigan when I was a kid about 10. The boat had 4 down riggers (2 lines each) and some outriggers (a lot of lines) but I don't remember how big it was. It seemed huge to me. We had been quietly trolly for about an hour when a couple of lines hit within a few seconds of each other (FISH ON!). Then something really odd happened. One of the middle down riggers first hit, then the boat jerked, then the downrigger ripped out of the mounts and tumbled overboard into the deep. The captain came from the bridge and started cutting lines and cussing. We didn't catch any fish. And he couldn't (or didn't) explain what had happened. It was kinda scary as I recall. Years later dad said the boat was rotten right there. I've always had my doubts and have wondered but dared never to speculate. What happened is still a mystery to me 30 years later. In my mind, JAWS had moved to Lake Michigan.
I’d say you’d caught yourselves a reef, a pinnacle, or both.
