Getting out:
Wade to water deep enough to use the fins, hammer out. This crap of sitting and trying to pick your way out is a recipe for disaster, the less time you spend in the surf zone the better, just pound straight out as fast as you can and dont get sideways to the waves. You might run face first into one or two, but it wont be many.
Getting in:
The EASY way is to stay pointed OUT and let the waves slowly bring you in backwards, that's the easiest way to avoid getting turned sideways, you maintain rudder authority. paddle/peddle a few times if one is about to break on you and that will keep you from getting surfed. get washed in till your in knee deep water or so then hop out with the boat between you and the beech, NEVER be between the boat and the surf, a wave will try to park it on your head.
Of course the fun way is to surf in, but on a fully loaded fishing rig with rods and everything that's probably rather foolish, its fun in a sea kayak though!
