Construction rules The boat must be newly built for the current Cub Scouting year. As much as practical, the boat should be substantially built by the Scout with parental supervision. The boat should use every part from the BSA Raingutter Regatta Kit. Additional parts, decals, paint, and glue are permitted. Overall width shall not exceed 2 1/4 inches. Overall length from bow to stern (including rudder) shall not exceed 7 inches, nor shorter than 6.5 inches. The mast must be upright and can be no taller than 6.5 inches from the deck surface. The boat must have a single hull. Although you might find designs for double hulled boats on the internet, our Pack rules mandate that all boats must be single hull. The sail may be trimmed and shaped, but may not be larger than the material supplied. The keel and rudder may be glued anywhere on the boat, but cannot cause the boat to exceed 7.00 inches in overall length. Details such as figures, decals and paint are permissible as long as these details are securely glued or fastened to the boat. The scouts are encouraged to decorate their boat, as they will also be judged for design, and awards given to the top boats in each rank. You can add material and items to the boats, but keep in mind that lighter boats will generally be faster. Race Rules Two boys at a time will race against each other. They will be called based on the number assigned at registration. Each boat must start with the back of the boat touching the end of the rain gutter. When the starter says go, the boys will propel the boats by blowing on the sail only. The boys' hands must be behind their backs at all times, unless the boat turns over or is stuck on the gutter. The boy may use his hand only to upright his boat or to remove an impediment (i.e. if the boat is stuck on the gutter). THE BOY MAY NOT ADVANCE THE BOAT WITH HIS HAND AT ANY TIME. The Race Manager and Race Stager will stand at each lane to judge violations.
