welcome to GLF Kenn. Yes, you can fish them without downriggers. I would suggest fishing with dipsy or walker divers, and inline weights. Divers are weighted disks that will take your bait down and to the side. For inline weights, look into the torpedo divers, I think they would be a good substitute for fishing without downriggers. For reels you are going to want a reel with a capacity of 300 yds of 20 lb mono give or take. I like the Okuma convectors for a mid-grade reel. For rods take a look at the Shimano TDR's, good rods that won't break the bank. For baits, flies spoons and plugs will probably all work but I have not fished that area so I don't have any local knowledge on what works there.
