I need closure on something

[Swimmer]

I was sitting on the long dock at West Chop about three-thirty one morning about ten years ago. It was blowing over my right shoulder about 30 m.p.h. and it was only 40 deegrees. I was fishing with what could only be described a very hevaey duty 5m blank 10' long rod. Big reel loaded with 40 pound test. I was floating bait off the bottom because there is a lot of kelp type stuff there. The rod bends, I grabbed it. Theirs no turning this fish. I pulled back and planted my feet the best I could. I positioned myself at about a 45 degree angle with my feet up against the piling. This fish was swimming south towards middle ground and I wasn't going to stop it. I had three hundred yards of line on this reel. It got to the end and I was allready prepared. i was holding as best I could. I am not a small or weak person. Quite the contrary. No more line the fish kept going. I cut the line. The fish just kept going. Estimate how big a fish that was for me.
