Navigating ships through shallow-water ports, boat channels, man-made canals, and estuaries requires knowledge of the time and height of the tides, as well as the speed and direction of the water as the tides move in and out. This information is critical to sailing ships because they have to take advantage of the tides and currents to maneuver correctly. The captains of large transport ships also need to be aware of the tides because navigating a large ship through shallow, narrow channels leaves little room for error. Because the movements of the earth, moon, and sun are predictable, tide characteristics such as tide height, zero point, and mean lower low-water level are predictable. Tide height is usually measured from the low-water mark, which is considered the zero point. This procedure is simple in areas where the tide is relatively constant.

When you do find the fish in a spot, slow things down, because chances are there are a bunch of them. This is when the low tide falls below the average for that area. The moon's gravitational pull, especially around the new and full phases, causes these negatives, which are seasonally compounded by forces resulting from the northern hemisphere's tilt away from the sun. Tack a hard winter wind on top of these already drastic tides , and you can see the water level a foot below average, depending on where you are in the state. The farther north you go, the bigger the tide swing is. First and foremost, safe navigation is of the upmost importance during these tides.

Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and to a much lesser extent, the Sun and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude or " tidal range ". The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide pattern of tides in the deep ocean , the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry see Timing. They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day.

In many coastal regions, tides rise and fall twice every day. December 06, By Brenton Roberts.

This is common in many places along the Gulf of Mexico. These levels are the highest and lowest levels which can be predicted to occur under average meteorological conditions, and under any combination of astronomical conditions; these levels will not be reached every year.
