Variable-draft light amphibious vehicle and boat equipment

The invention discloses variable-draft light amphibious vehicle and boat equipment which comprises a boat body and further comprises a water depth sensor arranged at the head of the boat body, an air bag arranged at the bottom of the boat body and a controller. The water depth sensor is in signal connection with the controller; the controller judges the draught degree of the ship body according to the water depth value detected by the water depth sensor and controls starting of the air bag based on the draught degree. The bottom of the ship body is further provided with wheels for the ship body to travel on land. Through the detection function of the water depth sensor, intelligent control over different states of the air bag can be achieved, the waterline of the equipment can be changed, complex underwater landforms can be better dealt with, shallow reef island landing is completed, and the equipment is high in applicability, easy to operate and good in economical efficiency; the problems that traditional island climbing equipment cannot adapt to complex underwater landforms, the transportation efficiency is low, the economical efficiency is poor, the ship body and propellers are greatly damaged by the beach-flushing island climbing mode and the like are fully solved, and wide application prospects are achieved.
