Non – lateral markers are navigation aids that give information other than the edges of safe water areas. The most common are regulatory markers that are white and use orange markings and black lettering. They are found on lakes and rivers. Other markers use vertical or horizontal stripes.
Hazard ( Diamond ) Marks random hazards such as Shoals and rocks. Information concerning the hazard is illustrated within the orange diamond.
Boats Keep Out: A white buoy or sign with an orange diamond and cross means that boats must keep out of the area. Black lettering on the buoy or sign gives the reason for the restriction, for example, SWIM AREA. Danger: A white buoy or sign with an orange diamond warns boaters of danger – rocks, dams, rapids, etc.
Terms in this set (9) These are white with red vertical stripes and indicate unobstructed water on all sides. They mark mid-channels or fairways and may be passed on either side.
When any boat/ship is returning to port (including an Sb-42) and they see a red buoy they need to respond by passing the buoy and keeping it on the starboard side/right side. This is because buoys come in two colors, green and red, each of which indicate what side of the buoy is the safest course to travel.
Safe water markers have red vertical stripes set against a white color background. They signify that there is safe water on all sides which is unobstructed. These red and white markers show mid-channels of fairways, being passable on all sides.
To determine a ‘ safe speed ‘ for your boat, take into account the following factors: The visibility conditions (fog, mist, rain, darkness) The wind, water conditions and currents. Traffic density, type of vessels in the area and their proximity.
When using locks, boaters should: Have fenders and at least 100 feet of rope to use in securing your boat inside the lock. Follow the lock attendant’s instructions and proceed slowly. Avoid passing another boat when inside the lock, unless directed to do so by the lock attendant.
Control Buoys They are white with two horizontal orange bands and an orange circle on two opposite sides. Inside the orange circles will be a black figure or symbol indicating the restriction. If they carry a light, the light is a yellow flashing (Fl) four seconds, light.
These special- purpose buoys have orange symbols on white pillars, cans, or spars. They are used to: Give directions and information. Warn of hazards and obstructions.
For those who are paddling or boating on intercoastal waterways, yellow buoys are used to designate a channel. When someone sees a yellow square, this is a sign that they need to keep the buoy to the port side. On the other hand, yellow triangles should stay to the starboard side of the boater.
The expression “red right returning” has long been used by seafarers as a reminder that the red buoys are kept to the starboard ( right ) side when proceeding from the open sea into port (upstream). Likewise, green buoys are kept to the port (left) side (see chart below).
Lateral markers are buoys and other markers that indicate the edges of safe water areas. Green colors, green lights, and odd numbers mark the edge of a channel on your port (left) side as you enter from open sea or head upstream. A type of green marker is the cylinder-shaped can buoy.
Inland Waters Obstruction Markers: These are white with black vertical stripes and indicate an obstruction to navigation. You should not pass between these buoys and the nearest shore.
They mark the edge of the channel on your port (left) side when entering from the open sea or heading upstream. These buoys use the lateral marker shapes, colors, and they have a matching colored light. These are permanently placed signs attached to structures, such as posts, in the water.
