Test of davit with water weight. Water weights are water filled bags which are designed as a safe, practical and economical method of non-destructive testing and checking the structural integrity of cranes, davits, lifeboats, link spans, ramps and lifts, floors and bridges. [1]
Off-load This release mechanism requires the weight (load) of the lifeboat to not be on the hook when it is released. This includes the Titanic-era Monomony hook design that requires someone to remove the hook from the lifeboat by hand. But this type also includes the hydrostatic system many lifeboats use now.

[citation needed] Modern lifeboats have a motor; liferafts usually do not. Large lifeboats use a davit or launching system (there might be multiple lifeboats on one), that requires a human to launch.
The RNLI engineering department in Poole worked with the tractor company New Holland to design a small launch tractor for stations which operate D-class inflatable lifeboats. The powerful small diesel engine gives out 45 hp (34 kW). [1] The tractor is undersealed to resist a saline environment. The tractor is fitted with turf tyres, which ...
The United States Coast Guard operates four 52-foot Motor Lifeboats (MLBs), which supplement its fleet of 227 47-foot Motor Lifeboats. [1] These vessels were built in the late 1950s and early 1960s, and displace 32 tons. [2] The four vessels are all stationed in the Pacific Northwest. The vessels are remembered for the many lives they saved ...
TEMPSC Lifeboat in Bristol harbour, England TEMPSC is an acronym for "Totally Enclosed Motor Propelled Survival Craft", which was originally designed for offshore oil and gas platforms in 1968. The first-ever TEMPSC was spherical in shape, had a flat bottom, a single hook, with a total passenger capacity of 28 passengers and a fire-retardant ...
The MES consists of five components. Controls – used to initiate the device in an emergency situation. [9]Stowage box – contains essentials for the evacuation, including the chute and the fixed appliances, such as seats, rails, etc. [10] Composed of marine grade aluminum along with inflation cylinders, usually kept on the deck taking as little as 4 m 2 of storage space.
