Welcome to S-B
I think everyone will agree that if you had just one thing to use anywhere in the world to catch any kind of fish to survive, it would be a bucktail jig. It's simply that good and that universal.
A lot of boaters and charter types swear by jigging a larger bucktail when trolling but they can also be casted into shore or structure as if you were fishing from shore.
Basically, jiggin a bucktail for bigger fish means getting a bucktail right down to the bottom, even to the point that you occasionally hang up. You are constantly moving yur rod tip up and down to create a pulsing in the jig.
Slower trolling speeds and try a few different colors, Black, Red, Green, White, Pink, & Purple are colors I've seen and used before. Make sure the jig is heavy enough to get to the bottom and remember you occasionally want to snag - that means you're down deep enough... I used to race some smaller sailboats and I was always told that if I wasn't capsizing occasionally, I wasn't racing hard enough. Same thing applies to snaging a jig.
Hope this is a start & good luck....
