I've ran my 16 ft. through there many times in all tide conditions, because I like Cornet Bay for launching.
Deception Pass is stunningly beautiful and exciting- I particularly like to run the motor 3,000rpm and stay in one spot because of the advancing current!
As someone else mentioned, just look out for the large rips- they look like toilet bowls being flushed. I think one of those could swallow you if you got in there. Otherwise, have a great time!.
