Boating Markers and Buoys Quiz

Study Notes

Buoys function as navigational aids, guiding boat operators through waterways and indicating hazards or controlled areas.
Green buoys are kept on the right when returning from open water (green on right, returning upstream) and red buoys on the right while heading away from open water (red on right).
The preferred channel is indicated with red and green colors in junctions, where green is placed on top and preferred is to the right.
Can buoys are green with odd numbers, marking the port side, while nun buoys are red with even numbers marking the starboard side.

Lighted buoys have colored lights that correspond to their navigational markings.
Daymarks are fixed signs indicating navigational information, commonly featuring red triangles and green squares.

Variations in lateral markers exist in the Intracoastal Waterway (ICW) and the Western Rivers System, which affects navigation for boaters in certain regions.

Squares provide informational guidance on supplies and directions.
Diamonds indicate hazards, while crossed diamonds signal exclusion areas off-limits to boats, such as swimming or construction sites.
Circles mark controlled areas like no wake zones.

Plow-style anchors are effective for most boats, obtaining holding power by digging into sediment.
Fluke-style anchors (Danforth) are lightweight and also secure by digging into sediment.
Mushroom anchors should only be used for smaller vessels due to their limited holding capability.

Select an anchoring site with ample room, depth, and a suitable bottom. Lower the anchor slowly from the bow, not the stern.
Use 7-10 times the anchor line length relative to water depth for secure anchoring.
Maintain visual references to ensure the boat doesn't drift.

Low-head dams, known for their dangerous recirculating currents, can pose risks to vessel operators.
Fluctuating water levels due to tides or floods can create navigation hazards.

Commercial vessels have priority in locks; remain 400 feet back until signaled.
Flashing lights indicate when to stay clear (red), approach safely (amber), or enter the lock (green).
Ensure to have fenders and line ready when inside the lock and follow the lock attendant's orders.

Some bridges may have limited clearance and require communication with operators for opening, while debris can create hazards around bridge structures.

PWC operators must understand local laws and perform routine checks on their craft.
Steering is done by jet propulsion; losing throttle can result in loss of control.
Stay mindful of proximity to other vessels and avoid blind spots, while maintaining noise levels to prevent disturbance.

Ignition safety switches, prop guards, and interlocks serve to enhance operational safety and prevent accidents.
Wireless sensors can shut down engines if a boater falls overboard.

Operators should have knowledge of tides, weather, and navigation charts for safe boating practices. Proper preparation and adherence to safety protocols can greatly reduce risks associated with watercraft operations.
