DAYBEACON: A fixed navigation aid structure used in shallow waters upon which is placed one or more daymarks.
Daymarks are permanently placed signs attached to structures, such as posts, in the water. Common daymarks are red triangles (equivalent to nuns) and green squares (equivalent to cans). They may be lighted also.
DaymarkA signboard attached to a daybeacon to convey navigational information presenting one of several standard shapes (square, triangle, rectangle) and colors (red, green, orange, yellow, or black).
red daymark
A navigational aid used in the United States and Canada to mark a channel. Red square daymarks should be kept on the right when returning from a larger to smaller body of water. Green daymarks mark the other side of the channel.
Range Daymarkers are found in pairs with one higher than the other. Range markers indicate the center line of a channel by having them lined up as you pass through the channel. They will have vertical colored panels to assist in lining them up.
Daymarkers are fixed to the ground instead of floating, but are painted red or green, and assigned numbers like the buoys. They appear on the chart as a magenta or green triangle.
Red daymarks are triangular in shape and have even numbers. The numbers are in order with the lowest numbers at the entrance of a channel or harbor and the highest numbers located deep within Hampton harbor. The daymark on the right is red daymark #2.
