This navigational tool provides predictions of water levels at a specific coastal location over time. Primarily used by mariners, fishermen, and beachgoers, it offers insight into the cyclical rise and fall of the sea due to gravitational forces. For example, a historical rendering details predicted high and low water marks for a particular date range at a seaside location, assisting in planning maritime activities.
Its significance stems from its ability to enhance safety and efficiency in coastal environments. Historically, these documents were crucial for safe harbor entry, successful fishing expeditions, and coastal navigation. The information facilitated informed decision-making, minimizing risks associated with unpredictable tidal conditions. Understanding past tide patterns can also reveal long-term coastal changes and trends.
