SCAMP RACING

The course and the number of laps will be decided on the race day.

Mark rounding:- When approaching and rounding a buoy the outside boats must give

room for all the inside boats to get round safely. If a boat hits a buoy and bounces the

wrong side then the boat must turn back and re-round the buoy on the correct side.

The boat must have the top cover and windscreen fitted when racing

NOTE Racing will immediately be abandoned if young waterfowl are seen on the

pond.

SCAMP Building Rules

Building Materials. Wood, plastic or fibreglass. NOTE:-Carbon fibre is not allowed.

Hull Build The hull shall to be built to the plans that are readily available.

NOTE The plans were not printed to the scale the designer intended but SMBC decided that

we would build the boat using the printed scale as it would be easier.

This means that some of the sizes written on the plan are wrong, ie the proptube size, boat

length and beam are all incorrect.

distances measured from the plan give a Length of 636mm and a Beam of 236mm

A prop tube of 8” is recommended.

2025 Rules are shown below (section 1 to 7)

1 The proptube can be any length and must come through the hull at the position and angle

shown on the plan.

The diagram below shows how far the tube can protrude.

2 A fillet can be fitted between the proptube and the hull bottom to give support and help reduce vibrations.

3 The motor can be placed anywhere forward of the hull end of the proptube.

4 Water cooling does not have to be used for the E.S.C. (reliability and warranty of the controller may be affected) i.e. done at owners risk!

5 Numbers must be fitted to the side of the boat minimum height 3.5cm contrasting colours to be used so they can be seen easily.

6 Any rudder can be used providing it does not have foils that provide vertical force up or downwards.

7 No battery change is allowed during racing unless there is an obvious battery problem.
