As defined by the International Code of Signals, a swell that is 8-10 feet in height would be described as what?

A swell measuring 8-10 feet in height is categorized as a "Moderate Swell" according to the International Code of Signals. This classification helps mariners understand sea conditions and prepare for navigation accordingly. In maritime terms, swells are waves that have traveled from their original formation point and are defined by their height and impact on vessel handling.

The designation of "Moderate Swell" indicates that while the waves are noticeable and can affect smaller vessels, they are not yet at the level that would cause severe difficulties for larger ships. This understanding allows mariners to gauge the sea state, which is crucial for safe operations at sea. Recognizing the classification of swell heights assists in adjusting sails, course, and speed as necessary to ensure safe navigation.
