The tide clock, invented by an American innovator over four decades ago, was a crucial maritime device during ancient times. As its name suggests, it was designed to measure the time difference between the occurrences of wave surges, and its effectiveness and practicality made it a valuable tool for comprehending tidal movements and simplifying necessary seafaring calculations. Consequently, the tide clock became an essential navigation instrument used aboard ships.
How Tide Clock Works?
The functioning of a tide clock is dependent on the gravitational pull of the moon on the ocean’s tides, and thus requires precise adjustment according to the moon’s lunation cycle. To use the clock, seafarers must first set it to the first high tide of a particular lunation cycle. Based on this calibration, the device can provide calculated predictions of future tidal events. In order to ensure accuracy in tidal calculations regardless of a vessel’s location, the tide clock must be calibrated according to the specific water geography being navigated.
Unlike other clocks, the tide clock features two tidal notations on its face – low tide at the lower end and high tide at the upper end. The numerals placed between these notations represent the time between the two tidal actions, which lasts for over 12 and a half hours. The precision of the tide clock has made it possible to create tidal tables that predict statistical data about future tidal actions. These tables, which are technology-driven successors to the original tide clock, have helped the device stay in step with advancements in engineering science. Despite being a simple battery-operated gadget, the tide clock remains a crucial tool for seafarers navigating the seas.
Tide Watch Utilisation Exemptions
Although the tide watch is a valuable navigation tool and can be utilized with great success in most oceans and seas, there are certain water geographies where it cannot be used due to unpredictable natural fluctuations. In the southern coast of the United States, particularly the Gulf of Mexico, the tide watch becomes redundant and mariners are compelled to rely on other electronic navigation tools instead. However, such areas are limited in number and do not significantly impact the tide watch’s effectiveness in other regions.
