RC Model Boat Classes
There are many different classes of racing, with the RC model boats being defined by both engine capacity and hull configuration.
There are three basic types of hull configuration, these being Mono Hulls, Tunnel Hulls and Hydroplanes
These three types of hull are placed in classes according to the capacity of the engine used. The classes as defined by the AMPBA are:
| Class | Engine | Ignition |
| A | up to 3.5cc | I.C. |
| B | 3.51cc to 7.5cc | I.C. |
| C | 7.51cc to 11cc | I.C. |
| X | 11.1cc to 30cc | I.C. |
| 16cc to 25cc Petrol | 16cc to 25cc | Spark Ignition |

For local club days we are able to define additional classes to suit the type of boats that members have. If you would like a local class created, contact a committee member. Note: local classes can only be used within the club and can not be used at any event governed by AMPBA rules.
