The 44' motor lifeboat or MLB was for many years the Coast Guard's standard heavy weather & surf rescue response platform. Designed and built by the service itself, the MLB-44 was introduced in 1962. They replaced the 36' MLB, which dated to a hull design of the 1880s. The "44" has a welded steel hull, powered by twin diesels, capable of 15 knots, with a range of 190 nautical miles. They also have a towing capacity of 125 tons. It has a normal crew of four, with enclosed heated accommodations.

MLBs are built to withstand the most severe conditions and are capable of effecting a rescue at sea even under the most difficult circumstances. Their range of stability is in excess of 175 degrees, and they are rated for surf conditions up to 20 feet, seas up to 30 feet, and winds up to 50 knots. They are self-bailing, self-righting, and almost unsinkable: if overturned, the vessel will return to an upright position in 30 seconds or less.

The US Coast Guard once operated 110 of these vessels, with many more built for foreign services. Since 1997, the 44' MLBs have been replaced in service by the new and significantly faster ( 25 knots ) and even more capable 47' MLB. The service plans to eventually acquire 200 of these aluminum marvels. Meanwhile, the old 44s can look forward to new careers in third world fleets, or, in the case of these two, peaceful rest as artificial reefs.

Surprisingly, of all the devices that make up an underwater diving kit, the last to be developed was a suitable air reservoir. Demand air valves ( regulators to you and me, ) masks, fins, snorkels, weights, even drysuits may be found in the historical record up to several hundred years ago, but because of material and manufacturing requirements, the high-capacity high-pressure portable air cylinder is a relatively recent development. ( Jacques Cousteau often gets credit for something he did not invent - the demand-valve regulator predates him considerably, although he did much to perfect its application to diving. )

2016 Update

Litigation has caused manufacturers to leave the market, and be replaced by others, who then left, and then others come back. From year to year, there's no telling what brand of tanks may be available, but the specs and recommendations below should apply to any.
