Yes that GPS track says it all.
Sometimes at Hoisse to Thasis Inlet you have to troll DEEEEEPPPP!!! No one else seems to but we have cracked the secret a number of times going 90 - 120 on dead days.
Another thing to try is keep going faster and faster on a deep troll to the point where the balls are at 45 degrees and the lines are ready to blow out of the release clips, then put the kicker in neutral and let the ball fall to vertical, then start over.
If the fish are on squid they love this approach. Looks like a squid going deep to escape a predator. Use a glow hootchie for this approach.
Will be up on the 13th for a week. May be river mouth jigging, but best I could do for timing.
