Racing Classes currently available

1. Offshore Sport

This is the step up from RTR. In this class the maximum engine size is .32ci but any motor and any hull is permissible (Cats and V-Hulls). This class also allows RTR racers to 'step up' by using higher performance race engines and aftermarket parts.

Typical motors include Go, CMB NovaRossi, Rossi, OS to name just a few.


2. Tunnel Hull F1-style

These boats must resemble a scaled version of a real Formula 1 GP boat. Utilizing a motor on a drive-leg setup as per normal outboards. Hulls sizes are depended on the class that’s raced but can be anything from 29inch to 54 inch. The classes running are 3.5cc nitro, 7.5cc nitro and 26cc Gas.

Watching these boats ride on a cushion of air and drifting round some marker buoys can take ones breath away

The name says it all. Offshore style boats in essence scaled versions of the UIM P1 Unlimited class with 26cc petrol engines capable of speeds in excess of 70kph, some reaching 100kph. These boats are big fast and spectacular. Racing on the coarse mere centimeters from each other takes precise movements and quick reactions.
