Well, actually you can catch and keep native kings inside the strait if you fish out from Sail Rock past Neah Bay and out to Tatoosh Island. That is a large body of water that is area 4. We have caught lings when fishing for kings near Wada Island. You don't have to go "outside" to catch kings. It helps though.
You only have a short time, 7/31 to catch kings out there now. Good luck.
