HISTORY: The California Cracker Box is a racing runabout design popularized on the American west coast shortly after the Second World War. The design places a 283 ci. small-block Chevy engine (originally cannibalized from wrecked Corvettes) in the middle of a 15ft flat-bottomed boat, with driver and engine man sitting behind it with their backs almost against the transom. Power hits the water by way of a straight propeller shaft exiting the bottom of the boat. As the class developed boats got faster, and presently race in the 80 to 90 mph range. In recent years the Cracker Box hull has become a favourite with radio-controlled boat modellers.

Full size fun!

MONTGOMERY MODEL BOAT CLUB (MMBC) 1/10th SCALE "STOCK CLASS" CRACKERBOX RULES

In the spirit of racing a 1/10th scale model of the American Power Boat Association Crackerbox One Design Runabout, yet to make the boat as fun, competitive and inexpensive as possible; the following are the MMBC rules for this Class.

1.) Hull Specifications

a.) Hulls must be within 1/8th inch of the appropriate 1/10th scale hull. Boats may be made of any material and can be a pre-assembled, kit or scratch built boat.

b.) The deck/hatch must resemble that of the full scale hull.

c.) Two drivers of scale-like appearance must be used in the driver/rider compartment. The driver must have orange colored helmets and live jackets.

d.) The dead rise of the transom must be 3/8ths of an inch in total (3/16th of an inch per side), with a transom width of 6 3/8th inches.

e.) The hull must have “P” numbers (example: P-100) displayed, but may be painted/decorated in any other way desired.

2.) Drive Train

a.) A single motor must be coupled directly to a straight drive shaft. A flex shaft may be used in a straight tube.

b.) The propeller must not extend beyond the back edge of the transom.

c.) Steering must be by a rudder mounted under the hull or attached to the transom.

3.) Power Specifications

a.) Power must utilize any “brushed” stock, 27 turn, 540/550 can motor. Cooling systems are permitted.

b.) Batteries must be NiCad or NiMH “Sub C” size cells (6 pack). Li-Po’s are NOT allowed.

4.) Race Format

a.) Heat racing format will be used.

b.) The Contest Director shall determine the scoring format, i.e. total points or a "winner take all" final heat format.

(Crackerbox Boats may be run at either pond, but due to limited pond size and wildlife endangerment at the "Theater" pond, races are to be held at the "Vaughn Road" pond only. If running a fast boat, please be kind to wildlife and remember SAIL BOATS HAVE RIGHT OF WAY!)
