The 50 fathom line or as it is often known-"the hiway" can be a very productive area to fish. I too fish structure, points, backeddies, reefs etc but when that doesn't work I head out deeper. The hiway-is not some strict narrow band of water right at 300 feet of depth-it maybe at 260 or 500 feet of depth but usually it is where you find transiting fish-I believe it is temp and bait related. If I know of structure there I will try it. If I see birds or bait I try there. Usually I fish very deep-220,240 ft of wire. We usually start higher and quickly work our way down. If we get a hit-we mark it and do an expanding square search. If we get a fish we don't just blindly move on but try to reproduce depth, bait, direction of travel etc. Some areas are better than others. Last year the hi-way at Winter Harbour didn't produce as well as it usually does-yet the fish showed up in the Columbia in droves-we kept on going out and found lots of fish in 500 ft-water was warm last year-might have been the reason. Can get awful lonely out there-make sure you have the WX ,gas and boat to do it. Most guys will give you good areas to try-I certainly do. Pre-planning is a good idea-for instance try all your in-shore points and if no joy have an area you want to try
Off-shore. Think about your lures-I use bait-but some guys can't stand that because of the depth and how often it has to checked. Great place for hardware, plugs spoons etc. Usually big fish so big spoons turds etc are productive late july aug. I'm rambling on-I could write a book 'so I'll shut-up. Must be time to leave Baja and get the boat in the water. LOL
