Nautical customs refer to the traditional practices and etiquette observed by sailors and maritime communities. These customs often include specific rituals, such as the ceremonial raising of the flag or the practice of whistling to summon favorable winds. They also encompass rules of conduct on board ships, ensuring safety and respect among crew members. Additionally, nautical customs can vary by region and culture, reflecting the unique history of different maritime communities. For example, the British Navy has its own set of traditions, while fishing communities in New England may have distinct practices related to their local environment and heritage.
