Man overboard! There are times when rescue boats must be placed over the deck and into the water to assist those in distress. However, launching a boat from a larger vessel is not easy, and the captain may need to make these launches and recoveries day or night—with little or no light. And it will need to be done in the open ocean, and that's not often flat and calm.To further complicate things, the rescue boat may be launched while underway—the boat doesn’t stop. Allied Systems, a fabricator of material handling equipment, was contacted for these and other reasons. The marine industry desired a safer launch and retrieval system for rescue boats—particularly in…
