What is the speed of the fastest RC boat?

As of my last update, the fastest RC boat is the "Spirit of Australia," which reached a speed of 88.5 mph (142.6 km/h) in 2010. However, there are various commercial models that can achieve speeds exceeding 50 mph (80 km/h). Advancements in technology continue to push the boundaries of speed in remote-controlled boats, so newer models may have emerged since then. Always check the latest records for the most current information.
