Welcome to the site!
NC is the largest supplier of blue crab (Yep, even larger than MD), you should be able to catch crabs almost anywhere!
I fish (crab or fin fish) the sound side all the time in my small boat with an electric motor.
Even caught small ones bare handed...the kids get a kick how I let them bite onto my fingers and pull them out of the water.
Be careful in that yak or canoe!
One gets loose in that yak...they don't let go even if you break they're claw off!
Now, how about introducing yourself over here in the General Discussion!http://www.bluecrab.info/forum/index.php/topic,1947.0.html
Welcome and good luck!
