GSB designs and manufactures two-point and three-point seat belts, as well as four-point and five-point harnesses built specifically for the demanding marine environment. Our products are trusted by boat builders, operators, and safety system integrators worldwide. Whether used on passenger boats, tug boats, patrol craft, or high-speed vessels, GSB seat belts and restraints deliver dependable protection and long-term performance on the water.

We provide solutions for most marine seating systems currently on the market and offer custom-engineered restraints for specialty applications. GSB’s engineering expertise and collaborative approach have led to the creation of innovative systems that help protect crews and passengers from the unpredictable forces of the sea. Every belt and harness we produce is designed to perform reliably through exposure to saltwater, vibration, and constant motion, conditions that can quickly wear down lesser components.

Safety on the water requires more than compliance, it demands precision. At GSB, our engineers design seat belt systems that account for the unique dynamics of marine operation, such as vessel acceleration, rolling, and wave impacts. Each assembly is dynamically tested to ensure proper restraint and durability, even under repeated heavy loads.

Our application engineering process allows us to adapt our designs for a variety of marine seat types, from suspension and shock-mitigating seats to fixed or rotating helm seats. GSB’s in-house testing facilities verify tensile strength, corrosion resistance, and webbing performance after salt spray exposure. The result: marine-grade restraint systems that provide reliable protection without compromising usability or comfort.

Operators and crew spend long hours at sea, often in unpredictable conditions. GSB belts are designed for smooth retraction and minimal interference, allowing natural movement during operation while keeping users securely restrained.

Our anti-cinch technology and wide-angle retractors reduce belt tightening from motion or vibration, helping prevent discomfort during extended periods at the helm. Materials are carefully selected for resistance to UV rays, saltwater, and humidity, while ergonomic buckle placements ensure fast, one-handed release when needed. Whether for passenger comfort or professional use, GSB restraints are engineered for day-in, day-out reliability.

All the seat belts from GSB meet or exceed SAE J386 and FMVSS 209/302 safety standards, ensuring reliable protection in high-impact scenarios. We work with aftermarket suppliers and OEMs to provide products that are field-tested and certified.
