Rules of the Road - Part III

Range Markers

ON OUR 2022 Baltic Cruise, while cruising the waterway from the Baltic Sea to Stockholm, I noted a series of different markers. They were characterized by a kind of weird symmetry, in which one would be the reverse (like upside down) of the other.

A LITTLE research enlightened me. These are know as "range markers." As the dotted line illustrates, navigators line them up with each other to get positioned safely and correctly in the channel.

NOW YOU know a little something about range markers. 😄
