I try to go fishing to Prince Rupert 2 times each year. usually in June (For the springs, & August, for coho) Excellent fishing. Stay at campground, and pull my boat out each nite. Never leave your boat w/ equipment in in it there overnite. Only public boat launch, is "Cow Bay" Good launch, but very extreme tides there. Only ever onch that had to wait for a higher tide to launch. Excellent fishing. But if you go far far offshore, try to have a fishing buddy w/ you IE: second boat. I use the depth sounder, look for holes, then anchor. Usually do o.k., for bottom fish. Caught a 49.5 ling cod last year, in a new hole. Released it, hope it did o.k. Salmon, have done very well with, usually in depths 60 - 30 feet. On anchovies.
Have a good one.
