The Raingutter Regatta is a fun Cub Scout activity. In this race, Scouts build a trimaran sailboat using a kit. The boats are then raced down a length of water-filled rain gutters. The boats are powered by the boys blowing into the sail through a soda straw. The fastest time overall determines the winner.

Here are some common rules for the Raingutter Regatta:

• You must use all the pieces in the Trimaran Boat Kit.

• You cannot add weights to your sailboat.

• No sails may be used other than the one supplied in the official kit.

• The sail must be mounted on the mast using holes provided in the sail.

• The boat must be no longer than 7 inches in length, nor shorter than 6 1/2 inches in length.

Here are some tips for winning:

• Practice long, steady breaths.

• Your breath should hit the sail directly behind the sail and just below the center.

• Focus on a small, concentrated area.
