Understanding the Beaufort Scale

This video tutorial covers Lesson 15 of the Competent Crew course, focusing on the Beaufort Scale, a system for measuring wind strength. It explains the scale's history, its application in yachting, and provides detailed guidance on sailing techniques for various wind conditions, from calm to hurricane. The tutorial emphasizes the importance of understanding wind speeds and adjusting sails accordingly, offering practical advice for competent crew members to handle different wind strengths effectively.
