How do life rafts work?

How does a life raft inflate itself?

Inflatable lifeboats may be equipped with auto-inflation (carbon dioxide or nitrogen) canisters or mechanical pumps. A quick release and pressure release mechanism is fitted on ships so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel.

How long will a life raft last?

Raft manufacturers warranty most life rafts for 10 or 12 years, based on servicing according to their recommendations. In fact, a raft that is kept dry and is regularly repacked may last for 20 years or more until it is condemned by a factory-authorized service station.

How long does it take to repack a life raft?

Life raft repacking is federally regulated. Remember to plan well ahead when sending a life raft in for repacking. The process can take a week to three weeks depending on how busy the facility is and life rafts can only be shipped by ground freight because they contain hazardous materials.

What is the purpose of life raft?

A rigid or inflatable raft designed to hold people abandoning ship. Liferafts are required as a back-up to lifeboats and in some small ships are allowed in lieu of lifeboats. Davit-launched liferafts or throwover inflatable liferafts are in use.

Can a life raft survive a hurricane?

The Givens Buoy Raft is the most stable life raft you can buy. It’s the only life raft that can ride 35 foot swells and breakers without capsizing. It’s the only raft that can withstand hurricane force winds, the rotor downdrafts of rescue helicopters, and the pounding of severe storm seas.

Why forward liferaft has no HRU?

Note: A liferaft stowed forward at a distance of over 100m from other survival craft does not need be fitted with an HRU. This is because the unit may release the liferaft after becoming submerged in heavy bow seas.

When you upright the life raft and the raft will come over on top of you you should?

A) After the raft is in the upright position on top of you, dive down to prevent your life preservers from fouling as you come out. B) As the raft flips to the upright position, you will be thrown clear.

How much does a liferaft cost?

Pricing for new liferafts suitable for typical cruising sailboats is readily available from the major online chandleries and varies from around $1,000 to around $4,000 depending on manufacturer, number of people, mounting method, and coastal vs. offshore.

How do you test liferaft?

Inspect the container/valise for external damage. Open the container, unfold and inflate the liferaft. Test the inflation system (gas cylinder, firing head, high pressure hoses, non-return valves etc.). Visually inspect the liferaft and its fittings for corrosion, abrasion and deterioration.
