What height is noted for the highest unfixed point on the vessel?

The highest unfixed point on a vessel is crucial for ensuring safe navigation, particularly when it comes to passing under bridges or navigating in channels with height restrictions. When identifying this height, one must consider details such as the mast, antennas, or any other obstructions that may rise above the standard structure of the boat.

In this context, the height of 20'9" accurately reflects the highest unfixed point, which is typically the mast or other equipment that can be adjusted or is not permanently attached. This specific measurement allows for adequate clearance calculations and helps prevent potential accidents or damage when the vessel is in motion.

Understanding the significance of identifying the highest unfixed point assists coxswains in making informed decisions while operating the vessel, particularly in environments where vertical space is constrained. Proper knowledge of this height is essential for navigating through areas with limitations and ensures compliance with navigational safety standards.
