US Coast Guard 47-foot Motor Lifeboat Monterey off Half Moon Bay California
The 47-foot MLB is the standard lifeboat of the United States Coast Guard (USCG). The 47′ MLB is the successor to the 44′ MLB.[5] At Station Chatham where the new 47-foot boat would draw too much to get over the bar, the 42-foot Near Shore Lifeboat was designed to replace the 44' MLB. [6] The 47' MLB is designed to weather hurricane force winds and heavy seas, capable of surviving winds up to 60 knots (110 km/h), breaking surf up to 6 m and impacts up to three G's.[3] If the boat should capsize, it self-rights in less than ten seconds with all equipment fully functional. The boat's hull and superstructure are constructed entirely from 5456 marine grade aluminum. Designed with a hard chined deep "V" planing hull,[7] the 47' MLB exceeds its displacement speed.[clarification needed] 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 Employing cruise-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. Situated less than 1 ft (30 cm) 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. It is situated at the combined center of rotation of the ship.
