A catamaran is a one-piece ship that is formed by connecting two
elongated hulls laterally together. The hulls are connected by deck
bridges, each with independent pushing devices. Because the two
boats are connected horizontally, they can withstand large wind and
waves at sea and are not easy to overturn. At high speeds, the two
slimmer hulls can significantly reduce the resistance of the hull.
Moreover, the total width under the same tonnage is large, and the
transportation efficiency is high, which is common in the design of
boats for competition and entertainment.
The width of the catamaran is much larger than that of the single
ship. Its stability is obviously better than that of the single
ship, and it has the ability to withstand large wind and waves. The
catamaran not only has good maneuverability, but also has a
resistance peak that is not obvious. Features such as large load.
Compared with single-tonnage single-hull ships, the total width of
the catamaran is larger, so there is often a larger deck area and
cabin volume, which is especially suitable for loading low-density
goods that are large in size and low in weight. Higher
transportation efficiency. Dividing a single hull into two can make
each hull more elongated, which may reduce the wave-making
resistance of the ship. Especially at high speeds, the wave-making
resistance is greatly reduced.
The power catamaran uses two elongated hulls, most of which are
combined with the turbojet engine to push the water quickly to the
ship. According to Newton's third law, a huge forward propulsion
(reaction force) can be obtained. ), it is faster to push than the
ordinary propeller, and at high speed, the resistance of the
elongated hull is greatly reduced. The high-speed catamaran has the
advantages of relatively stable, less water resistance, lighter
weight and less difficulty in overturning.
The light weight, strong mechanical properties and corrosion
resistance of the aluminum alloy make the aluminum alloy widely
used in the construction of the catamaran. The marine 6061 aluminum plate produced by Mingtai Aluminum is the ideal material for the
