Tom, I hope to see you out there this year.
The locations provided were good. I have nothing to add as to location except this. What you are looking for in those areas is the edge of a shelf between 225' and 300'.
Stay nearby and head for your floats whenever anyone gets close. I lost a pot and setup to the depths prior to adding a bunch of weight to my already heavy pots, so I know what that's like. What really sucks though is that I have lost two due to theft. We tend to fish only two pots and to limit everyone on board within a few hours. We had been running back to port 25-30 mins away to swap out friends. Last year we lost two pots, for sure, to theft. The method used was to pull up along side between us and the floats, swap floats and move on. Then late in the day they pull the swapped pots after the victim has given up and gone home. I lost one when I made it easy by leaving the area and the other when I was within eyesight but chatting with friends. Granted, I was in the Edmonds area,but if you search shrimp pot theft you will see issues in the islands as well. So be smart and just a little paranoid.
You get the added plus of causing folks to deploy a little farther from your location. This is another issue, since to deploy 300' down you want 350' of weighted line and if some dork comes along, fails to read the tide and crosses you then one or both of your floats are going down. This may not be a big issue up north, but we get a little more pressure on the fishery down here.
