What is a "tide table" used for?

• A. A guide for fishing times
• B. A chart that lists expected times and heights of tides for specific locations
• C. A record of past tidal patterns
• D. A schedule for boat races

Answer: (B)

A tide table is primarily utilized to provide sailors, fishermen, and coastal residents with essential information about the expected times and heights of the tides at specific locations. This data is crucial for navigation, as tides can significantly influence water levels and currents, impacting a vessel's maneuverability and safety. Understanding the timing and extent of tides helps sailors plan their trips, avoid grounding, and optimize their speed and efficiency when headed to or from shore.

The tide table typically includes information for different days over a month or more, detailing high and low tide levels, which is critical for activities dependent on tidal movements. For example, knowing when high tide occurs can help mariners identify suitable times for entering or leaving harbors that may be shallow during low tide. In addition to navigation, this information is valuable for recreational activities such as fishing, beachcombing, and other maritime endeavors that may hinge on tidal conditions.
