Hey Ryan,
Marine Areas 8-1 thru 9 open May 1-June 15 for lingcod and other regulation can be found here:
http://wdfw.wa.gov/publications/00957/wdfw00957.pdfCatching sanddabs is easy with either Berkley Gulp soft baits or mussles that you break off a piling at low tide.
Tie up two 7/0 Octopus hooks about 6" apart mooching leader style on a three foot piece of 50 lb test. Tie your "ling leader" to the bead-chain end of a 6 oz mooching sinker and you're in business!
Hook the sanddab through the upper jaw or skull, but don't go so far back that you penetrate the brain and kill him... you want him to swim
Find a rock pile or pinnacle (there are some dandies off of Double Bluff) and deploy the rigged 'dab... let the ling eat it!!! then let him eat it some more... then reel into the bite...dont jerk!
If the wind is blowing you'll have to back into it and hover over your intended target water. Do some chart study and you'll find plenty o' pinnacles out there!
Good luck!
