DSB 470 IRB Inflatable Rescue Boats are exceptionally lightweight thanks to their ultralight Hypalon fabric construction and smaller outboard engine. Survitec's IRBs require smaller davits, making transport and servicing easier, more efficient and economical. Built for a variety of end-users, including commercial and defence organisations, the DSB Inflatable Rescue Boats couple operater-friendly, advanced performance capabilities with durability and innovative design.
