What are tide tables?
What are tide tables? Not surprisingly, boats rely heavily on tidal information. Traveling through shallow ports and narrow intracoastal waterways or under bridges is a risky venture if you don’t know what’s going on with the tides. Depending on the area, the difference between high and low tides, or the tidal range, may be more than 49 feet (15 meters) [source: NOAA: Tides and Water Levels]. If you’re a sea captain steering your ship under a low bridge, underestimating the range could be devastating. Fishermen often draw on information about the tides to improve their catches since certain species of fish may congregate during periods of high or low water. In addition, strong tidal currents can corral fish into one area, and if fishermen know when that current will occur, they’ll hit the jackpot. Tide tables are also useful in planning
