Bob,
In the way you have worded this I would have to say that it is not a good idea. There are too many exceptions that would have to be made. The resulting regulation would just add another layer of confusion to the existing novel of regulations we allready have.
The first problem is safety. There are some areas where leaning over the boat is downright dangerous under certain weather conditions. The Columbia comes to mind in many places. Also, since you are thinking statewide rule, the safety concern pops up again in all marine waters under certain conditions and in certain boats. I have been on several boats where I would have to be strung to the rail by my ankles to reach the water.
Another problem area is when the regulations require a minimum size. Some people will undoubtedly have the urge to post "if it is close to being undersized just release it." Problem is that is not a reasonable request for the angler who fishes every once a while and is lucky to catch the fish in the first place.
I think there are some specific fisheries where some of this could be considered. For instance, special nets required for the catch and release fisheries could merit more discussion. But for the majority of the fisheries we need to just rely on education.
