2. Product Structure
A. The design consists of two main buoyancy chambers made of natural rubber, an
insulated floor and an automatic erecting canopy for all-weather protection that
incorporates doorways, vents and a rainwater catchment system. The canopy is
supported by an arch which is inflated via the upper buoyancy tube. There is a
boarding ramp which is inflated via the lower buoyancy tube. (See Figures 1 & 2).
The liferaft is made from the following parts:
• Two buoyancy tubes: one installed on top of the other with a floor
suspended below them. This gives a high freeboard.
• A canopy, which is erected automatically by an inflated arch tube.
• Water pockets, which are installed on the base, make the liferaft stable
and control the drift subsequent to the launch.
• The buoyancy chambers of the liferaft are black and the canopy is a high
visibility orange.
B. The liferaft has the internal and external equipment as follows:
1. Lifelines which are attached around the interior and exterior of the buoyancy
tubes.
2. A rescue line and quoit which are located inside the liferaft.
3. Automatically deployed internal and external lights.
4. Automatically deployed sea anchor.
5. Survival equipment, which is contained in an emergency bag(s), are stowed
inside the liferaft.
6. A righting line on the base is used to right an overturned Liferaft.
7. Boarding ramp.
8. Rainwater catchment device on canopy exterior.
9. Lifting Bridle. (Only on Davit Launch liferafts).
