Are you new to Nanaimo?  I'm always looking for a friend with a boat!  :)  

Just off Nanaimo there are a few good spots.  The Five Finger Islands are a good place to start and you can work your way North to Neck Point.  A little further out (SE) there's a popular fishing spot called Thresher Rock.  Also, right now I've been hearing of people launching from Nanoose and heading straight out and fishing the small islands - either jigging or trolling flashers.

I hope that gives you a start.

Good luck and tight lines!
