I think the experience on the OBMG boats is VERY typical. They are pretty good at what they do. I have fished offshore around them quite often. If you see one (you will usually see more), it might be a good ideal to stop and fish that area? Just make sure you give them "lots" of room. They seem to find, "the right place at the right time." Just don't crowd them.
The other thing mentioning the "cattle boats"... There is NO WAY, I would plan on leaving Ucluelet during the 6:00am rush hour! Been there - done that... and running in their wake at the end of the channel, gets old "quick"! Leaving around 5:30 or 6:30, it is a LOT nicer, especially in the fog!
Both are good areas and I don't think you can go wrong with either. I have paid my "dues", in both. If you are fishing the inside at Bamfield, the Robertson Creek Hatchery does have a lot of influence there, to the tune of between 2/3 and 3/4 of the Springs. I personaly would be there closer to the second week of August? But, no one can really predict exactly when that "main" run will hit! Ucluelet and offshore, is just the opposite. Those fish are migrating down the coast with 2/3 headed to the U.S. with the bulk of the rest going to Nitinat and Fraser. That is a way larger amount of fish to target!
I have never had to go any farther then "Outer Southbank" out of Ucluelet during the first week of August? Many times you can find fish right outside the mouth of the channel, both north up to "Wya" and south to "Cree"? But, then that also depends on the time frame you are there? You very well could find fishing the best at "Big Bank"?
Southbank and Bigbank both, hold a LOT of "resident Springs" and Coho! That's were the use of the "hoochies" comes from. If you miss the run, "that fishery", itself can be very good. Here, maybe this will help you decide?
Here is a list of some of the better spots in the areas. The rating and species is only based on my experience and what I caught. The more **** only means, I personaly caught more fish there, it has nothing to do with the quality of that location.
This is what it looks like on a chart!
Oh, and "yes", I have fished everyone of those locations and this should answer the email question about my boat.
