When crossing a TSS, what angle should a vessel aim for?

When crossing a Traffic Separation Scheme (TSS), vessels should aim to cross at a 90-degree angle. This approach is recommended because it minimizes the time spent within the TSS, reducing potential interference with the heavy traffic typically found in these areas. By crossing at a right angle, vessels can maintain their course and speed more effectively, and this maneuver enhances overall safety for both the crossing vessel and those navigating within the TSS.

Choosing a straight line or any angle other than 90 degrees may expose a vessel to increased risk of collision, as it could lead to longer interactions with traffic and create confusion about the vessel's intentions among other mariners. The TSS is designed to organize maritime traffic, and crossing it at a 90-degree angle aligns with the principles intended for efficient and safe navigation.
