They are also known as "channel markers". [14] [failed verification] They can normally be used coming into and out of the channel. When lit, they are also ...

The Corps of Engineers marks the Intracoastal with channel markers like this one. Locations along the Gulf Intracoastal Waterway are defined in terms of statute miles (as opposed to nautical miles , in which most marine routes are measured) east and west of Harvey Lock, a navigation lock in the New Orleans area located at 29°54′32″N 90°05 ...
Watercraft navigation lights must permit other vessels to determine the type and relative angle of a vessel, and thus decide if there is a danger of collision. In general, sailing vessels are required to carry a green light that shines from dead ahead to 2 points (22 + 1 ⁄ 2 °) abaft [note 1] the beam on the starboard side (the right side from the perspective of someone on board facing ...
