We fished this past Friday just north of old C can in Canadian waters.Had done well there the past few weekends.Caught one right away but started noticing grass on our trolling gear.After another 30 minutes of nothing and clearing grass on all 4 lines decided we needed to move.Headed north a few miles but was too much grass also We headed east to the weather bouy and the grass was not a factor there.We got our 12/26 lbs but took us close to 4 hrs.The best setup was dipsey 3 setting at 80 and 1 setting at 60.Gold double Willow worm harness and monkey puke spoons were what caught.Had a couple spoons on TT 40 on our inline boards at 75 and 85 that also caught.I was doing something with a rod when I heard an unusual noise.I looked to the rods and one of the rods drags was screaming.I yelled to John to grab it.He was just finally able to get some line back when I noticed our inline board getting pulled in too.I grabbed that inline rod but the board dove.I gave it slack but the board didn’t surface.I thought we were going to lose it all.Then John said it’s gone.Whatever grabbed it got off luckily The board surfaced and we got the tangled mess in.Not sure what could be big enough to pull so hard and get off. Chrome or walleye or some junk on the bottom.
