DSB 3.9 SR Semi-Rigid Inflatable Rescue Boat

Heavy-Duty, Long-Life Rescue Boat with Enhanced Manoeuvrability

The DSB 3.9 SR Semi-Rigid Inflatable Rescue Boat is built for maximum durability and exceptional manoeuvrability, offering a highly reliable solution for commercial marine and defence applications. Constructed with reinforced Hypalon seams and a UV and abrasion-resistant Hypalon fender tube, this semi-rigid inflatable boat ensures long-lasting performance in the most challenging maritime environments.

The boat features an aluminium sandwich hull, which is both seawater and capillary crack-resistant, providing superior durability and extending the boat’s life cycle. Designed with a self-draining concealed hull for additional safety buoyancy, the DSB 3.9 SR is optimised for manoeuvrability and handling, allowing for fast, precise navigation even in rough seas. With its advanced bow design and spacious internal deck, this boat is ideal for rescue, patrol, and tactical missions.

Performance

When underwater emergencies occur, a trusted, proven partner is essential. Our submarine escape and abandonment systems are engineered for precision, speed, and survivability, delivering reliable performance under extreme pressure and time-critical conditions. From deep escape scenarios to surface evacuation, they enable rapid, controlled responses when it matters most.

Innovation

We are continually advancing our submarine escape and abandonment capabilities to meet the evolving demands of naval operations. Through new material sciences, technological innovation and strategic partnerships, we push the boundaries of survivability — developing solutions that set new standards in performance, integration and reliability beneath the surface.

Protection

Sub-surface emergencies demand absolute confidence in protective systems. Our escape and abandonment solutions are designed to safeguard submariners from depth to recovery, delivering thermal insulation, flotation, and life-support performance under the harshest conditions. Proven through rigorous testing, they provide the protection needed when submariner survival is the priority.
