The tackle configuration known as the Alabama (Umbrella/Yumbrella) rig as it is commonly promoted is not legal in Minnesota waters. The rig pictured here is different than using a single lure with multiple treble hooks that is designed to catch just one fish.
Instead, the Alabama/Umbrella/Yumbrella rigs are artificial lure/baits that involve many separate lures/baits attached via wires to a fishing line. Consequently, these rigs are not a single artificial bait/lure, rather a collection of multiple artificial lures/baits each capable of catching a fish.
In my opinion, the link I posted is pretty clear in the differences. If you want to argue specifics, hypotheticals, or need more clarification, talk with a CO. I was just trying to help. I didn’t think people would try to nitpick so much.
