Which mark would indicate a lateral passage between hazards?

A lateral mark is specifically designed to indicate the port and starboard sides of a navigable channel. In the context of the IALA Maritime Buoyage System, lateral marks are used to guide vessels through safe passages, especially in areas where there are hazards such as rocks or shallows. By using these marks, mariners can easily determine their position relative to danger and navigate safely between hazards.

In a typical lateral system, vessels should keep the designated color of the mark on their corresponding side (red on the port side when heading upstream, green on the starboard side). This function is essential in ensuring that boats navigate correctly and avoid any submerged dangers or obstacles within the waterway.

Safe Water Marks are used to indicate that there is safe water all around the mark, and they do not indicate a passage between hazards. Cardinal Marks indicate the safest waters in relation to hazards but do so by showing the direction of safe passage rather than marking the sides of a channel. Isolated Danger Marks signify a hazard in the water but do not provide direction for navigating between hazards. Each of these mark types serves a specific purpose, while lateral marks are uniquely suited for guiding vessels along a designated route.
