THAILAND DRAG BOAT RACING

(RAAP—017)

In Thailand, a unique form of motorsport involves high-powered engine racing on water using specialized small watercraft. These boats, which are similar in size to a kayak and lack seats and steering wheels, are constructed using basic boat building techniques. The sport is characterized by its use of powerful engines, ranging from 150cc single-cylinder units to larger, unlimited cc twin-cylinder motorcycle engines.

The construction and modification of these watercraft are typically carried out by mechanics in local workshops. The operation of these boats requires the pilot to either sit or kneel while manoeuvring the craft. Control is achieved through manipulation of the prop shaft and engine propeller. Pilots adjust the trim by altering the angle of the prop and the boat’s tail in the water, using their body weight to steer the craft in a manner akin to motorcycle handling.

These lightweight watercraft can reach speeds of up to 160 kilometers per hour. The sport involves constant adjustment of weight by the rider to counterbalance the torque produced by the engine prop as the boat accelerates. Due to the absence of safety measures, such as seatbelts, helmets, or protective structures, the sport is considered highly dangerous. Despite these risks, watercraft racing enjoys considerable popularity in certain regions of Thailand, with numerous owners and teams participating in competitions across the country.
