HANS III Model 20 Med QC ST

The HANS III Model 20 Med QC ST is a head and neck support system engineered for high-performance boating and marine racing where sudden acceleration, deceleration, and impact forces place extreme stress on the cervical spine. Designed for medium-sized frames, this SFI 38.1–certified device protects against whiplash and lateral neck trauma during aggressive maneuvering, rough water conditions, and emergency stops. Boaters and racers who operate performance vessels in demanding environments rely on this proven restraint to reduce injury risk and maintain neck stability under extreme G-forces.

The HANS III uses a sliding quick-click tether mechanism that integrates with your helmet anchor point, creating a dual-restraint system that limits head rotation and forward motion while preserving visibility and comfort during extended water time. The plastic-reinforced construction keeps overall weight manageable at 3.21 lbs, preventing fatigue while delivering rigid support where it matters most—the trapezius and upper thoracic regions. The quick-click design allows rapid on-water donning and removal, critical for situations where you need to transition between cruising and high-speed running, or quickly exit if needed.

This medium-size configuration suits boaters and competitive racers with standard to athletic builds who demand SFI certification for sanctioned events or serious offshore work. The helmet anchor compatibility ensures seamless integration with your existing safety gear—no modification required. Compact dimensions (13.7 × 4.3 × 15.7 inches) allow storage in tight cabin spaces or emergency kits. Whether you're running center console in choppy seas, competing in offshore powerboat racing, or operating in commercial marine environments, the HANS III Model 20 Med QC ST delivers race-proven protection that has become the industry standard for neck and head restraint.
