Description
The United States Coast Guard CG47225 motor life boat with its crew is patrolling the Harbor during the 2023 Cleveland National Air Show. The 47-foot Motor Life Boat is from Station Grand Haven, Mich. The boat was originally built by Textron Marine Systems and delivered on September 4, 1998 as the standard lifeboat of the United States Coast Guard (USCG). It is a first response rescue resource for the Coast Guard in high seas, surf, and heavy weather environments.
The 47-Foot motor Lifeboat is designed as a first response rescue resource for the Coast Guard in high seas, surf and heavy weather environments. They are built to withstand the most severe conditions at sea and are capable of effecting a rescue at sea even under the most difficult circumstances. They are self-bailing, self-righting, almost unsinkable. If the 47 Motor Lifeboat should capsize, it self-rights in less than ten seconds with all equipment fully functional.
The frame is composed of 17 vertical bulkhead frames, each of which is welded to the deck and hull, and five of which are watertight. The hull and the superstructure of the craft are made entirely from 5456 marine grade aluminum. Its hard chined deep "V" planing hull allows the 47′ motor life boat to exceed its hull speed. Situated less than 1 ft above the water line are recessed retrieval wells, allowing for easier recovery of persons and jetsam, and easier boardings. A watertight survivor's compartment is equipped for comprehensive first aid.
Employing "fly-by-wire" control systems, the boat can be operated from four different locations: two from the enclosed bridge, and two amidships from an open bridge. Because of the “by wire” system the boat is controlled by joysticks instead of wheels. The crew size is typically four plus room for up to 30 passengers.
