I've been fishing out of a canoe for more than 40 years, first my Dad's and now my own.
Mine is a 16 foot, home build cedar 'stripper' model.

Like Cat I often stand up and paddle or pole in calm water.
Lifejackets are essential; I have fallen out when goofing off

Make sure you have a net for landing fish!
