Horseshoe Buoys & Ring Buoys

What Are Horseshoe Buoys & Ring Buoys?

Horseshoe buoys and ring buoys are among the most critical pieces of safety equipment any boater can carry. These throwable flotation devices are classified as Type IV Personal Flotation Devices (PFDs) by the U.S. Coast Guard — meaning they are designed to be thrown to a person in the water rather than worn. As their name suggests, they come in two primary shapes: the traditional closed-circle ring buoy and the open U-shaped horseshoe buoy, both of which provide buoyancy and a grip surface for a person overboard to hold onto while awaiting rescue.

Ring and horseshoe buoys are a critical part of any man-overboard (MOB) recovery system, designed for fast deployment and offering buoyancy and visibility when it matters most. Most are constructed with unicellular polyurethane foam for reliable flotation, and many feature floating polypropylene grab lines and high-visibility orange or white coloring to aid rescue. Some modern models can also be fitted with seawater-activated lights to assist with nighttime rescues.

Why Every Boater Needs One

U.S. Coast Guard regulations require that any vessel 16 feet or more in length carry at least one Coast Guard-approved Type IV throwable device on board. A Type IV Ring or Horseshoe Buoy carries a minimum buoyancy of 16.5 lbs. — enough to keep an adult's head above water while they await help. Because rapid deployment is so vital in a man-overboard situation, how a buoy is mounted and stored on your vessel is just as important as the buoy itself. Look for models that pair with quick-release brackets or rail-mounted holders for instant access at the stern or cockpit.

Key Considerations When Shopping

• USCG Approval: Always look for Coast Guard-approved Type IV certification to ensure your buoy meets federal safety standards.
• Size & Shape: Ring buoys typically come in 20", 24", and 30" diameters. Horseshoe buoys offer an open design that can be easier to get into while in the water.
• Grab Line: A floating polypropylene throw line allows rescuers to pull the victim back to the vessel — an essential feature for offshore use.
• UV & Corrosion Resistance: Marine environments are harsh. Choose buoys made with UV-stabilized materials to prevent cracking and fading over time.
• Mounting Hardware: Consider purchasing a dedicated bracket or quick-release holder to keep your buoy accessible and properly secured.
