Make the ultimate raingutter regatta racer

SAFETY FIRST: Ask an adult to help with tools you haven't used before.

A winning raingutter racer stays on an even keel, moves in a straight line, keeps the bow above water and does not drag.

If your boat does all this, it finishes ahead of any boat that can’t. Here’s how to build your winner.

WHAT YOU’LL NEED

  • Regatta Kit (BSA Supply No. 17090, $3.99, http://www.scoutstuff.org)
  • Fine sandpaper
  • Scissors
  • Polyurethane
  • Paintbrush
  • Superglue
  • Spray paint (optional)
  • Adult permission and/or supervision

WHAT YOU’LL DO

step1.jpgStep 1: Sand the balsa wood hull’s sides and bottom until smooth.

step2.jpgStep 2: Put the mast in, and bend back the mast to “rake” it a little. Take the mast out for now.

step3.jpgStep 3: Seal the hull, using two coats of polyurethane, then sand it smooth.

step4.jpgStep 4: Add the keel and the rudder. Put both on the centerline and at right angles to the bottom of the hull. Put the keel on as far back as you can, just ahead of the rudder.

step5.jpgStep 5: Glue the keel’s narrow edge next to the hull and the angled edge forward. This makes your boat harder to tip and quicker to right.

step6.jpgStep 6: If you paint the boat, keep it simple — spray paint works fine. Three thin coats make an attractive finish. Attach the mast after painting.

step7.jpgStep 7: Trim 1/4 inch off the top and 3/4 inch off the bottom of the sail. Cut a new bottom hole 1/2 inch above the old one. Clip off the bottom corners so they can’t snag the gutter.

step8.jpgStep 8: To keep the sail above the gutter, attach it so that the bottom is 1 1/2 inches above the deck. Glue the sail to the mast so that it can’t move. Attach the sail at right angles to the centerline.

HOW TO CAPTAIN THE BOAT

No matter how well you make your boat, victory demands a skilled captain. An even wind, for instance, moves the boat faster than do frantic puffs.

Practice long, steady breaths. Your breath should hit the sail directly behind the sail and just below the center.

  1. how do you make a good sail design

    • usually, you would want your sail slightly curved and wide to catch as mush air from the fan as possible. The curved sail design will help contain the air flow within the sail to help stability, as well.

  2. We had the boy scouts reffing(is that the right word) and they had lots of fun

    Rules now state that sail cannot be touching anypart of boat other than mast and must use all parts supplied with kit.

  4. yeah, I like my trimaran that i painted red.

  5. The last time I was in a raingutter regatta, I was the only one who put the sail connected to the bottom of the ship without the stick. That way, the sail wouldn’t turn to the left or right.
