What is the correct way to enter a TSS?

Entering a TSS (Traffic Separation Scheme) at as small an angle as possible is the correct approach. This method minimizes the time spent in the TSS and reduces the risk of collision with vessels that are navigating along the lanes of the scheme. By entering at a smaller angle, a vessel exposes itself less to the traffic flow, thereby enhancing the safety of the maneuver.

The design of TSS is to facilitate the orderly movement of vessels and to prevent conflicts, so maintaining a small angle respects the flows and allows better situational awareness for the vessel entering the scheme and for those already navigating in the lanes. This approach aligns with the principles of safe navigation and the COLREGs, which emphasize the need for caution and the minimizing of risk in congested waterways.
