What kayaking equipment required
The kayak paddle is a tool for athletes to move kayaks forward. A kayak paddle is a two-blade paddle with paddles on both sides of the paddle.
Its main structural feature is the perpendicular or near-vertical intersection of the two paddles.
According to the direction of the static water deflection of the blade kayak, the left and right paddles can be divided into left and right paddles.
As the rules do not have strict and uniform regulations on the size and shape of paddles, the development of kayak oars has changed extremely rapidly in recent decades.
The weight, length, shape, paddle, and paddle size of various paddles can be selected based on the athlete's height, technical style, strength, gender, and boat type.
Still boat
Canoeists are in a single leg on the boat, the other leg is in a square foot, and a single blade paddle is held on both hands.
There are left and right paddles. For example, the left paddler's right hand holds the "D" shaped handle. The left hand holds the paddle near the paddle, the right leg moves forward and the left knee rests on the pad.
Rowing boats do not have rudders. Athletes rely on paddles to maintain balance and control direction. Since each paddle has to be lifted after the paddle, and then it is inserted into the paddle, the speed of the boat is not as good as that of the kayak. The paddle frequency can reach 70 to 80 paddles per minute.
The raw material used to make the hull is aeronautical plywood or fiberglass. There is a limit to the length and minimum weight of a rowing boat.
The rules stipulate that the rowing boat must be manufactured symmetrically on both sides of the longitudinal axis of the hull, and there must be no rudder and any means capable of navigation.
The rowing boat can be fully open. If there is a covered deck, the enclosed part of the single rowing boat cannot exceed 150 cm from the bow and 75 cm from the stern. The open part of the double rowing boat is not less than 295 cm.
The open part of the four-person rowing boat is not less than 410 cm. Single rowing boats and double boats can be fully open with a minimum length of 280 cm; the edge of the ship (the upper edge of the ship's rail) can extend along the entire defined opening, extending up to 5 cm on the ship.
A boat can have up to three reinforcement bars, each with a maximum width of 7 cm. During the competition, various electronic or electric instruments should not be placed on board, including pumps, speedometers, fatigue gauges, and heart rate monitors.
Rowing paddles are tools for athletes to row a rowing boat. A rowing paddle is a bladed paddle paddle. There is a slight difference in the specifications for single rowing boats, double rowing boats, and quadruple rowing oars.
Rowing paddles are generally made of wood or fiberglass, and in recent years have been developed using carbon fiber as a material. The carbon fiber structure makes the paddle more robust, durable, light and easy to maintain.
The cross-section of the paddle is usually circular, so that the paddle has a better directionality, is conducive to force, but also makes the paddle has a greater resistance to bending.
The blades of a rowing paddle are different from kayaks, and the blades are symmetrical along the centerline.
Asymmetrical blades can create an unbalanced surface that produces torsional moments under dynamic forces. The blade of the rowing paddle plays a variety of functions for advancing, steering, and controlling the smoothness of the vessel.

According to the lifting mode, it can be divided into manual, Electric Standing Desk and Pneumatic Standing Desk.
The electric standing desk is divided into two legs standing desk, three legs standing desk and four legs standing desk, which is also called back-to-back standing desk. This back-to-back standing desk is a double desk with a screen connected in the middle to ensure personal privacy and beauty.
