I am very new at salmon fishing, so I am looking for a little guidence. I go out of Port Washington, Wi., and my boat is only a 17' Backtroller and no downriggers this year, only dipsies and offshore planer boards. So far I'v not done to bad, average trip is normally 5-7 kings. But that could be alot of just luck, but the last couple trips out not even a hit. The weather is getting colder so do I stay in alot closer to shore, like 30-50' or do I look for a certain tempature. I know it is fishing but a place to start would be a great help.
