Which of the following is a basic principle for safe sailing?

Understanding weather patterns and forecasts is a fundamental principle of safe sailing because weather conditions directly impact the safety of a vessel and its crew. Sailors must be aware of current conditions as well as potential changes that could occur during their voyage. By monitoring forecasts, mariners can anticipate storms, wind shifts, and other environmental factors that could affect their ability to navigate safely. This knowledge allows for better planning of routes and the ability to make informed decisions, such as altering course or seeking safe harbor when necessary.

Other options do not contribute to safe sailing principles: sailing alone eliminates the benefits of teamwork and assistance, using the largest vessel may introduce challenges in maneuverability and handling, and ignoring navigational buoys can lead to dangerous situations where vessels might run aground or collide with other objects. Therefore, knowledge of weather is key to maintaining safety on the water.
