Good topic guys.
Rover/others, Do you just put a third line close to the prop wash when you are in tight/shallow ie. 60 feet or less, or if you are stacked 45/75/ 90/120 down 150 ish would you put one out then ... or do you find they hit the high line close in only when you are shallow?
If your fishing Haida gwaii I don't know why you would be fishing that deep. If your there your likely after the big one that you wouldn't have the same chance to get anywhere else. These larger fish generally run in tight and shallow so that's where I target them. I don't think I fish anywhere deeper then 80ft generally less than 50. My riggers are often set at 25/35. It's easier for a fish to see above them than below.
If you do fish deeper why not toss one out the back. That's one of the great parts of fishing... You just never know what's out there
A few years ago The biggest fish that came out of our lodge was caught by some unguided quack running a coho killer on a weighted rod on a downrigger, fishing 150ft in 280 ft of water targeting halibut. He snagged the fish in the stomach. You just never know
