S3 MAX Multi-Axis Seats
Military-Driven Innovation for High-Speed Crew Safety
The new S3 MAX multi-axis shock mitigation seat represents a major innovation in safety for high-speed vessel crews and is designed to help reduce chronic brain trauma. The design was driven by the US military, to keep the occupants head as stable as possible when experiencing repetitive wave impact. This patent-pending design is specifically developed to help reduce lateral impact forces by stabilizing the occupant’s brain when experiencing high-speed, wave-slamming in extreme sea conditions.
Virtual High-pivot, Multi-Axis Design
Building on the proven vertical shock absorption of the current Shockwave S3 suspension seats, the S3 MAX introduces lateral shock absorption, enabling the seat to move side-to-side in response to side wave impact. This virtual high-pivot, multi-axis design delivers predictable, natural motion that enhances comfort, minimizes head movement, and reduces brain trauma — a critical factor in preventing long-term neurological damage and Chronic Traumatic Encephalopathy (C.T.E.), a degenerative brain condition linked to repetitive high-impact trauma.
Enhanced Safety & Comfort for Extreme Conditions
The new S3 MAX multi-axis seat takes safety and comfort to a new level for professional and military vessel operators and crew working in extreme weather conditions.
Building on the industry-leading S3 suspension that provides 8-inches (200 mm) of vertical wave impact shock absorption through the FOX Float H2O air sprung shock, the S3 MAX addresses the effect of side-on wave impact through a lateral shock absorption system that keeps the head of the seated crew member in a stable, static position by pivoting the seat to absorb the lateral acceleration forces. The virtual high-pivot design of the lateral suspension delivers predictable sideways motion that moves naturally with the body for optimal comfort and head stabilization.
A ground-breaking engineering design with a patent pending, the S3 MAX multi-axis suspension is designed to minimize chronic brain trauma, affecting mariners who make their living on the water as part of the Navy and Special Forces elite high speed boat crews.
Side-to-Side Travel
3 inches (80mm) of responsive lateral movement absorbs side impacts and lateral accelerations.
Hydraulic-Damped Stability
Precision damping ensures controlled, fluid motion in dynamic conditions.
Engineered for the Unexpected
Stay stable and supported through turns, chop, and wave slamming.
Seat Models & Cushion Options
The multi-axis shock mitigation system is available on most S3 seat models and compatible with all standard accessories.
G-Force Bolster Seat Cushions
Built tough for mission-specific duty, the G-Force seat features visco-elastic foam that absorbs impact and reduces point loading. Reinforced upholstery and kidney bolsters protect against wear from belt-mounted equipment. Commonly used
in military applications, the upholstery is easily replaceable to extend the seat’s service life.
Corbin High-Back and Mid-Back Seat Cushions
Widely used in commercial and government vessels, the Corbin seat offers excellent support and comfort. Available
in regular or heavy-duty upholstery, its closed-cell foam enhances the FOX shock’s wave impact absorption. Options include a fixed seat or a handle-operated drop-down bolster seat.
Vessel Applications
Navy, Army and Special Forces high-speed boat crews.
Addressing the Hidden Toll of High-Speed Operations
High-speed vessel crews face extreme forces that can lead to chronic brain trauma and long-term neurological conditions like C.T.E. The S3 MAX multi-axis shock-mitigation seat was engineered to address these risks and set a new benchmark for crew safety. A recent New York Times investigation highlights the severity of the issue among U.S. Navy Special Boat Teams, underscoring the urgent need for innovations like the S3 MAX.
The Shockwave S3 MAX Multi-Axis seat was unveiled on the first day of the WorkBoat trade show in New Orleans on December 3rd 2025.
Maritime Reporter TV was there to cover the unveiling and speak to Shockwave sales director Sean Gerrett.
