Most fisherman already struggle to keep fish. I would argue most also struggle to effectively keep just one line in the water as well.
Online forums such as this snap a very small picture of the overall anglers, and many here take it much more passionately which is the reason we all reached out into an online forum to be part of a conversation, bc we care, whether it’s about 2 lines, panfish limits, or the latest debacle on mille lacs. But it’s a reality, that the large majority of anglers are weekend warriors, the maybe couple times a year let’s rent a cabin, go up to the inlaws, etc. And with the busy work schedules, kids sports schedules, etc time is getting crunched outside of vacations. People simply don’t have enough time to fish as they use to.
To circle back now, many anglers when this gets passed will be like Hecks yeah! 2 lines! And they will buy the permit, and then let the games begin. Your trolling motor clinics, and marine shops will be flooded with lower units wrapped in fishing line, Cabela’s will be packed with guys to replace all the lost rods, broken rods, lost tackle from snags on bottom or as mentioned above gets wrapped in motor from forgetting about 2nd rod when going around a point, playing a fish, etc. It’s tough managing 2 lines for an experienced guy, 2 for your average weekend warrior, forget about it.
Fishing for most, as most iterate over and over here is much more than just catching. Once anglers find that managing 2 lines can be a big PIA most of the time and takes away from the fishing experience you will see the permit #’s drop back down.
With all that said, I’m a big shore fish guy, and if people ran 2 lines there it would suck really bad! Entire spots would be taken up by just one angler. So I’m on the fence about it still lol.
