GP-1 ULTRA HYDROPLANE RACING RULES

Boats must remain stock. Only hardware adjustments are 
allowed. Sharpening and scuffi ng are legal, but changing 
a prop is not. You are also allowed to paint or add decals if 
you choose.

A heat race is 6 laps and typically consists of up to 6 boats 

per heat. You can run as many heats per event as you like, 
but 3 to 5 is typical.

To start a race, set a timer to 30 seconds. Launch the boats 

and make one full clockwise lap. At the end of the lap, you 
need to be on the right side of the start line and going full 
speed. Being over the start line at the end of the 30 seconds 
puts you in last place. Be careful not to “jump the start.”

Cutting inside a buoy AT ANY TIME will incur a 50 point 

penalty per buoy.

Points structure goes like this.
