Engines customized for new Dutch search-and-rescue lifeboat vessels keep running after full rotation on axis. In thrashing, unforgiving seas, a capsized rescue vessel used to be a symbol of defeat. To withstand harsh conditions, sea vessels are designed to right themselves when overturned, but even more critical is the ability of the engines powering those vessels to withstand the 360-degree rollover with no compromise to performance. In these situations, the durability and resilience of a marine engine can be the difference between a rescue or a recovery.
