Aaron,

I've got pretty much that exact same boat. ('cept mine's a 14') I've been fishing the 522 area onf the Snohomish lately no problem. I launch at high bridge and run down. Just keep you motor in tilt mode and slow down where you see the stumps sticking out of the right channel just above the Sno / Sky confluence, and youll be fine.
