Wattpaddler

Wattpaddler is a powerful and user-friendly application designed for sailors, sea kayakers, and anyone interested in maritime navigation. It provides detailed information on tides, water levels, sea conditions, swell, wind, and nautical charts, making it an essential tool for planning safe and efficient trips on the water. The app covers all German reference and connection points, as well as Dutch and Danish tide locations, ensuring comprehensive coverage for users in these regions.

Official tide times for Germany, the Netherlands, and Denmark are displayed for the current year and will soon include data for the following year starting in autumn. This feature allows users to plan ahead with confidence. For Germany specifically, Wattpaddler integrates a 5-day water level forecast from the Federal Office of Sea and Navigation (BSH), along with weather reports from the German Weather Service (DWD) and official storm and strong wind warnings. Additionally, the app offers locally accurate weather forecasts from DWD and Yr.no, and includes warnings for medium (orange wave) and high (red wave) swells. Nautical warnings from BSH are also incorporated, and users receive notifications when new reports are available.

The app also features a unique function that helps sea kayakers and sailors calculate optimal time windows for passing shallow areas in the German Wadden Sea using the "rule of twelfths." This calculation considers spring and neap tides as well as water level forecasts for the next five days. A sine curve visualizes the current water level, providing an intuitive way to understand tidal patterns. Users can save a default location for quick access. For nighttime navigation, the app displays the length of civil and nautical twilight, the current moon phase, and moonrise and moonset times.

Moreover, Wattpaddler includes a dynamic nautical chart that clearly presents key elements of the North Sea Navigation Regulations, which are crucial for water sports enthusiasts. Users can search for specific days based on tidal conditions, such as "evening high tide on a Sunday in June." Underlined words in the descriptions link to additional functions that can be activated by tapping. For more details about the app's change history, users can visit the wattpaddler.de website.
