I did all the reading about how to catch a Halibut while trolling. We put on a big green and white hoochie and lowered it to the bottom on South Bank off Ucluelet. Then lowered the cannon ball to the bottom of the ocean. Drop the ball till it hits. Then raise, then drop... do this over till soon you are right about the bottom. Your rigger with be out quite a bit more than actual depth due to drag. Pay close attention to the downrigger in case you snag the bottom. While trolling close to the bottom 1.5 to 2 mph with a sweet spot of 1.7mph will get you into the correct speed for halibut. I got lucky and hooked up on a nice one. I think we had another one hit that got off as well.
