Sound travels over four times faster through water than air, so its imperative to be as quiet as possible to sneak up on fish. Move about the boat gingerly. Avoid dropping things on the deck, or slamming hatches, coolers and tackle boxes, keep your voice down and turn off the stereo. In skinny water, hull slap and the sound of a trolling motor also spook fish. So propel the boat with a push pole, or drift. If you must use a trolling motor, run it at low speed, shut it down before you get within casting range, and coast the rest of the way. Use a Power-Pole or stakeout pin to hold the boat in place while waiting for fish to come to you.
