Model
bamboo coracle is also a traditional basket boats of fishermen but was fitted
with floats become a means to help the boat when the storms at sea. It is the
brainchild of engineer Nguyen Xuan An, chairman VN gem.

Bamboo coracle pontoon boat shaped like a normal basket, which adds a layer surrounds
annular float a boat. Materials made of styro foam float that (foam), has been
used as heat insulation, sound insulation. The key technology is the valve
located at the bottom. Basket boat pontoon boats operate as normal when the
valve is closed. When the boat sank, victims must attempt to open the float
valve. Meanwhile, the country's thrust to make an impact on the water float
inside the boat to escape through the valve out and the boat will float to
become a lifesaver. Float valve victims, scooping water out of the heart
vessels to continue rescue work or wait. According to calculations by engineers
An, with basket boat float outside diameter of 2 meters, the maximum carrying
capacity of half a ton float, meaning that there must be a critical mass such
as new compression force making the submerged buoy flush with water . But to
ensure there is buoyancy floats above the water surface of 20 to 30 cm, the
boat should only carry a maximum of 4-5 people. Bamboo coracle buoy secure
wired to withstand impact of a storm. One end of the rope stuck on a boat, a
head belt buckles on belts, to help people on the boat always maintained
contact with the boat. Outside a pontoon boat also has a strap made seat rails
for the victims. An said he had made a basket boat buoy model size 1/4 real
boat and successfully tested in the aquarium. According to him, can be used
bamboo, rattan to make the material covered and fixed buoy floats on the boat
itself. Basket boat buoy prices higher than normal basket boat around 20-50%,
the area of use must also be reduced because the room for the float.
According
to Nguyen Vu Ha engineers, professional inspection centers, the Department of
Exploitation and Protection of fisheries resources, the Ministry of Fisheries,
his basket boat buoy An is a good idea, but to apply, requires empirical to
assess the full potential use. Vu Ha said that even using traditional basket
boats lifeline is not feasible, because the material is bamboo boat, clinging
vulnerable to scratches. Meanwhile, the criteria specified for the floats is to
smooth the surface. Want to make a boat float according to this idea, to build
a basket boat with lighter materials, have better floatation and smoother
surface. Ha said Engineer will report this solution should lead Exploitation
and Protection Department of fisheries resources in order to further the
exchange.
