ADVERTORIAL IMPACT MITIGATION
With decades of experience supplying seating for military and off-shore marine vessels, Carl Magnus Ullman shares his experience in seat design for superyacht tenders
the suspension unit, significantly improving the range of shock mitigation, as well as removing any need of setting-up or adjusting the seat. A lightweight person will be able to use the same seat as a heavy person without any need of adjustment.
Staying fit Travelling fast on small boats can be exhausting. Studies show that heart rate and oxygen consumption of riding standing or on fixed seats, can be comparable to running. The Ullman Seats effectively mitigate the impacts and natively optimise the posture, virtually eliminating fatigue. This lets you go further and faster, while keeping the crew, owners and guests safe, comfortable and rested throughout the journey, even at high speeds over rough seas.

acht tenders are becoming increasingly faster. With more powerful engines and more efficient
hulls, many can now reach speeds on par with sportscars. Imagine driving100+ km/h over a motocross track. This is not a far cry fromrunning a fast boat in rough seas.
High-speed boating is not risk-free Wearing lifejackets and using the kill- cord is crucial, but it won’t protect you from all perils. Acute injuries to the spine, neck, knees, and feet increase. Even overboard ejections take their toll, sometimes with fatal outcome. Shooting off a wave and impacting the next, can expose the hull and the humans on board to severe shocks coming from below as well as sideways.
The risks can be effectively mitigated To prevent back or spinal injuries and ejections, suspension seats must work for the full range of forces that the boats and its passengers are exposed to. Slamming impactscan exceed 10g and those containing lateral forces are the most dangerous. Therefore, the seats must effectively reduce vertical as well as lateral forces while safely supporting occupants at all times in complete comfort.
Synergising with the human body For comfort during long transits as well as to support the body during impact, it is crucial to maintain the optimal shape of the spine and the balance of the head. Ullman developed seats and suspensions based on medical science since 1989. All Ullman seats are shaped to put the user in an ergonomically correct position, significantly reducing the risk of injury. Having the feet in contact with the deck, gives valuable feedback from the boat, increasing situational awareness. It also allows the occupant to use their legs in synergy with
The development is still being done in cooperation with the most demanding operators, military special forces, police, and coast guards around the world. These operators must be able to go to sea even in the worst conditions. Therefore, Ullman seats are built to work in the worst imaginable conditions, where failure is not an option.
Built never to fail To make sure the seats never break and never degrade, they are built in the strongest and most durable materials, such as Swedish super duplex steel and vacuum injected carbon. By never compromising on protective capacity or quality, Ullmans have maintained their position as world leaders in shock mitigation seating for professional high- speed boats. With a unique track record of over 30 years, there have been no reported injuries when using the Ulmman seats.
Superyacht tenders
Ullman seats are featured on many sports and luxury tenders operating with some of the world’s most prestigeous yachts. The seats are handmade and often built and upholstered to a custom specification to match the mother ship’s.
