Just about every time I watch tournament fishing on television at least one competitor’s action makes me cringe. It’s particularly common on the high school and college circuits, but you see it amongst the tour-level anglers, too.
The offending mistake? Measuring a fish on the front deck, close to the side of the boat. Seriously, even if you have a viselike grip, the possibility, however small, that you’ll lose the fish outweighs any added convenience. Just ask Jim Bitter. It doesn’t take any more time or effort to measure your fish in the bottom of the boat. There aren’t any possible downsides that I can see, so make it a habit.
If you’re not sure that you can remember, screw your measuring board into the floor so you have no other option.
