Because each hull is long and narrow in hull design, the design waterplane is small, and the length-width ratio is large, so that wave-making resistance of the ship can be reduced, and the total resistance is reduced.
The patent CN 204250295U in China discloses a foldable trimaran side sheet body. The device consists of a sheet body, a connecting rod 1, a connecting rod 2, a connecting rod 3, a connecting rod 4, a revolute pair 1, a revolute pair 2, a revolute pair 3 and a revolute pair 4; the sheet body is hollow, has streamline appearance and is in a deep V shape in cross section outline; the connecting rods 1 and 2 are close to the direction of the bow; the rotating pair 1, the rotating pair 2, the rotating pair 3 and the rotating pair 4 are internally provided with self-locking devices, and when the connecting rod is connected and is reminiscent of rotating to a required angle, the connecting rod can be locked in the state. Through the flexible folding of 4 connecting rods, three kinds of operating conditions can be realized to collapsible trimaran side lamellar body: an extended state, a contracted state and a V-shaped state. When the ship encounters an emergency condition and needs to be quickly decelerated or berthed alongside, the side sheet bodies of the trimaran are in a V-shaped state, and in the working state, the sheet bodies on the two sides of the main ship body are impacted by water flow, so that the navigation resistance of the ship is increased, the quick deceleration of the ship is facilitated, and the parking stroke is reduced.
However, the trimaran still has certain drawbacks: 1. the requirement that the trimaran appears is that three hulls share a deck, thereby improving the space of the ship and meeting the requirements of helicopters and the like on the ship. The three hulls in the above patent do not share a common deck, and it is not seen that the three hulls have any effect; 2. above-mentioned trimaran is "V font" when the speed reduction is needed, and the effort of wave concentrates on the tip of V font to folding structure itself is comparatively single thin, consequently more easily breaks, and the practicality is not good, plays good speed reduction effect.
