What to Look For in Aviation Life Rafts for Rent

FAA Approved Aviation Life Rafts for rent vs. Other Rafts

When purchasing or renting an aviation life raft that will be used to keep you alive in an emergency, it only makes sense to get one that meets those highest standards available for comparison. SOLAS standards are very strict, as they are with all FAA approved gear. SOLAS standards require that approved aviation life rafts have a boarding platform, additional safety gear, and considerably more interior space than commercial-grade models.

Ballast

Most flat-bottomed survival rafts use a combination of water-filled ballast pockets and a cone-shaped sea anchor on a long (60' or more) line to prevent capsizing. The filled pockets resist the lifting action of wind and waves, and the anchor adds drag to keep the raft edge down. Toroidal-shaped and hemispheric ballast systems have proven most effective in preventing heavy-weather capsize. Bags with large holes for rapid filling also help keep the raft from blowing over before passengers can board.

Anchors

The sea anchor is an integral part of the stability design. It creates drag, prevents "riding", reduces the chances of capsizing, and turns the raft's hatch away from oncoming waves. Buoyancy Tubes Aviation Life Rafts come with either one or two automatically inflating buoyancy tubes. Short-term survival coastal rafts have one tube with two air chambers to prevent complete deflation in the event of a puncture. Double-tubed rafts found on all offshore and ocean-going rafts increase freeboard and reduce the likelihood of swamping. The second tube should support two-thirds of the raft's rated capacity when the largest buoyancy chamber is completely deflated.

Painter

When secured to your boat, the painter keeps the raft from floating away, and when pulled, it activates the inflation mechanism. More than one pull is usually needed to activate inflation because there is between 15-55' of slack to take in. Many painters have a colored marker indicating that the next pull will activate the carbon dioxide (CO2) cartridge to inflate the raft.

Manual Inflation

Temperature changes cause raft air pressure to fluctuate. When hot, the tubes expand and excess air pressure is released through the over-inflation valves. When cool, the tubes contract and will require topping off. Three types of manual pumps are available: an oral inflation tube, which is next to impossible to use effectively; a foot pump which doesn't work well on the inflated rubber floor; and an accordion-like hand pump that is, by far, the easiest to use.

Canopies

Although canopies shield survivors from sun, wind, and water, they can leave crowded passengers feeling claustrophobic and sick because of the reduced view of the horizon and, in some cases, a notorious rubber interior smell. Canopies with large entryways, portholes, and separately furled panels offer greater horizon views and increased ventilation. Double doors increase ventilation and light and make it easier to keep watch. Dark-lined interiors, like blue, are easier on the eyes; they diminish the sun's glare on a bright orange canopy. Canopies are supported by arches that keep the raft from inflating upside down and allow occupants greater interior room. Some arches are independent of the buoyancy tube and require manual inflation once occupants board. These rafts run a greater risk of inflating upside down but are easier to board from the mother ship.

Storage Containers

Rafts come in either a soft, flexible valise for below-deck storage or a durable fiberglass canister for mounting on deck. Canisters are usually bigger, heavier, and more expensive than valise containers. However, they can be mounted right on the deck, and will withstand the elements. The fabric valise may be lashed on deck for trips, but won't last topside in the long run. Also, be sure to secure it carefully, since it won't do you any good if it goes overboard. Carefully choose the most accessible and convenient location on your boat-account for raft weight and size. Aviation Life Rafts are useless if you can't get to it and safely launch it when you need it. Remember, anyone on board may have to carry it topside, and valuable minutes will be wasted if you have to pull it out of a cluttered locker.

Floors

Rafts have either single or double-layer floors. Double floors insulate passengers from energy-draining cold water, reduce the feeling of sitting on a half-filled water bed by keeping the floor from swallowing your feet and legs and help to eliminate the bumps and bruises from curious marine life. Certain designs secure the additional floor with button-like fasteners that create depressions in the raft floor and allow water to collect. Some floors keep passengers drier using a highly porous material to trap splashed water.

Capacity Ratings

These ratings specify the maximum number of people a raft will hold, based on a minimum of approximately four square feet per person. They do not consider comfort, space needed to perform raft maintenance and repair work, or room to store extra survival gear. If you plan to carry the maximum number on board, you had better hope for a quick rescue.

Ventilation & Visibility 

A serious cause of seasickness is the bright orange light which filters through the orange canopy fabric of other rafts. The soothing opaque blue coating that lines SWITLIK’s raft canopies prevents sunlight from passing through the canopy, so there is no flickering of light. The convertible canopy also provides four openings to allow for ventilation, and 360° of visibility.

Reflective Light 

High visibility raft canopy fabric and carefully arranged reflective patches enhance the visibility of the liferaft during rescue. The OPR has an external light that is triggered when the raft is launched, as well as a SOLAS-grade reflective tape and patches placed across the raft.
