Yep, and to add to that... "anywhere North and West" and you really don’t need any waypoints for that area!
You can actually catch them right on Bajo. Personally, I would be for at least that 150 feet, concentrating more towards 200 - 300 feet. Look for large rocky bottom area and those piles of rock (humps) and pinnacles.
Drop the bait to the bottom, then reel it up 5 feet. The slower the tide the better. Set the drift for deeper water to avoid hanging on bottom. As the tide starts to pick up, keep the boat above the bait by back trolling. When the tide gets above 2 knots and/or taking water over the stern, it would be a good time to start fishing for something else.
You can catch halibut at any depth; however, when a big one is taken from the above type of area another big one will usually move into that same area pretty quickly. And, that is exactly why one fishing an area on a regular basis is NOT giving out their good halibut spot. Once the big one is taken – the big halibut is gone, until another big one moves back into that area.
Halibut are territorial and congregate in the same size group. The big ones chase will the smaller ones off, protecting its feeding area. The bigger ones will also move off from the crowd of smaller ones. Which is also why if you are catching chickens, you usually won’t catch a large one in that specific area (e.g. any of the “chicken ranches”). So, take your pick of areas, as you can either go for a “barn door” or a “chicken” .
