Abstract

The invention relates to the field of ship accessories, in order to solve the problems that existing catamarans, especially high-speed catamarans, are prone to course deviation during navigation, and then the captain's steering times increase, energy consumption increases, and the economy of the ship decreases. , the invention provides a longitudinal stabilizing fin for a high-speed catamaran and an installation method thereof. The longitudinal stabilizing fin includes a core, an inner plate and an outer plate. The inner plate is a straight plate and the tail of the inner plate extends upwards to form a stern plate. The outer plate is formed by welding a sharp plate at the front end and a folded plate at the rear end along the welding line. The invention can effectively avoid the occurrence of yaw; can further stabilize the hull, prevent shaking and prevent lateral movement; the structure is simple and exquisite, which is beneficial to factory production, processing and installation.

Description

technical field [0001] The invention relates to the field of ship accessories, in particular to a longitudinal stabilizing fin for a high-speed catamaran and an installation method thereof. Background technique [0002] A catamaran refers to a "ship" that connects the upper parts of two separate underwater hulls into a whole with a reinforced frame. The two "hulls" are called sheet bodies, each of which has a main engine and a propeller. The strong frame connecting the two pieces is called the connecting bridge, and there are many cabins on it. It has the advantages of good stability, safety and comfort, and flexible manipulation. However, the high-speed catamaran still has some obvious defects. For example, the water-jet propulsion aluminum alloy catamaran high-speed ship draws seawater from the mouth of the flow channel by the water jet pumps of the left and right two pieces, and sprays it out from the tail to obtain forward thrust. When driving the ship to sail fast, d...
