What is the maximum height allowed for the masthead light on a vessel?

• A. 12 metres
• B. 10 metres
• C. 8 metres
• D. 15 metres

Answer: (A)

The maximum height allowed for the masthead light on a vessel is set at 12 metres. This regulation is established to ensure that vessels can be clearly seen from a distance, allowing mariners to avoid collisions, especially in navigation channels and during nighttime operations. The height of masthead lights is important for maintaining proper visibility. The 12-metre standard is also a means to differentiate between types of vessels based on their size and the necessary light requirements they must adhere to under the COLREGs (International Regulations for Preventing Collisions at Sea). Vessels over a certain length may be required to have their masthead light at this height to improve their visibility to other vessels, especially those that may be larger or have more restricted lines of sight. Maintaining this standard helps to ensure safety at sea and supports effective navigation practices.
