When crossing lanes in a TSS, how should a vessel orient itself?

When a vessel is crossing lanes in a Traffic Separation Scheme (TSS), it is crucial for the vessel to orient itself as nearly as practicable at right angles to the traffic flow. This practice enhances navigational safety by minimizing the time spent within the designated traffic lane, which reduces the risk of collision with vessels that may be following the traffic flow. By crossing at right angles, the vessel can quickly exit the shipping lanes, allowing for a more efficient and safer crossing.

Crossing at an angle to the traffic flow might result in the vessel being in the lane for a longer period, increasing the potential for encounter with other vessels. Similarly, being parallel to the traffic lanes would not be advisable, as this orientation could lead to confusion about the vessel's intentions and reduce the overall safety for all vessels navigating in that area. Being alongside other vessels does not appropriately address the need for safe maneuverability in a busy waterway where traffic patterns are regulated to prevent collisions. Thus, the practice of crossing at right angles is the most effective strategy for maintaining safety within a TSS.
