Two winters ago I was on a tog boat. It was a scratchy day but fish were there. I pulled in a keeper or two and had some life building in front of me. One of the mates came over and starting inching backwards step by by step until he was literally half way in front of me. The boat wasn't crowded with maybe only 15 fares but for the principle of it I didn't move at all. Sure enough he swings and pulls up a nice 7 or 8 pound fish from where my line would have been had I had some elbow room. Biggest fish of the day for the boat. The kicker is the capt was cheering him on standing near the wheelhouse directly over my head. I don't mind a mugging but not from the paid help. That was the one and only time I have ever stiffed a mate and haven't been back on that boat since. I also tell anyone who will listen.
But other than that situation , I really enjoying fishing with the mates and capt. I watched the capt of a boat I frequent last time I was out when he came down to fish for a few. I picked up new tips and he encouraged the educational value of that. I did what he did, selected a different size crab, rigged it a little different from what I was doing, and therefore limited out plus some and landed the two biggest of the day.
