Update: Just got back from our annual trip. The downrigger and related setup worked well. Thanks for all the advice. We were succesful with humpies but no others. We hooked at least two kings (fairly certain) but could not land them. Most of what we caught were on Pink Hoochies with a white flasher. Seemed to be the best combination. We tried other setups including spoons, green flashers and depths but the hoochies got the most hits. Most were caught in around 30' of water. Right off Eagle Point we found many bait balls being chased by schools of larger fish at around 100'. We assumed these were kings, we managed to hook two that put up a hell of a fight but lost both near the surface.
Thanks again for all the help and advice setting up my boat and related tips. My friends doubted our ability to catch salman this year and we limited out in about three hours.
