The Raingutter Regatta is similar to the Pinewood Derby or the Space Derby except that the models are miniature sail boats. Although the seas are only 10-foot lengths of raingutter filled with water, and the ships a mere 6 inches long, the race is a very exciting event. Each boy builds his own boat with supervision and help from parents, guardians or other family and friends. He also provides the wind for the sail with his own lung power.

The regatta boat kit, available from the Scout Shop, has a pre-shaped balsa hull, metal keel and plastic sail. The hulls are sanded and shaped, and are colorfully painted. Hull and sail are then decorated with decal kits, paint or any other form of decoration. The boats race in pairs on raingutter courses propelled by the boys blowing into the sails.

Please take a look at the rules before building your boat: Rules

The Space Derby is similar to the Pinewood Derby or Raingutter Regatta except that the models are miniature 'rockets' -- propeller-driven and powered by two or three rubber bands -- that travel along a heavy monofilament fishing line. The rockets are carved by the boys, with the guidance of their parents or other family members. Space Derby kits with building instructions are available at the Scout Shop.

Tips

• There are many alternative non-rocket designs such as: cruise missiles, boats (Titanic is always popular), planes, jets, etc.
• The little plastic straw MUST go over the hook (not just the shaft as the drawing in the space derby kit illustrates) This is where the rubber bands will hook on - the wire hook will cut the rubber bands without the plastic straw liner!!!
• Lubricate the rubber bands (spray silicon, ethylene glycol, castor oil, ...)!  Stretch them numerous times before loading, hand wind the bands numerous times before races (20 winds, then 40 winds, then 60, 80, 100) -- this helps relax the elastic properties of the band and makes it more pliable and durable (this is exactly why the clowns stretch the balloons before blowing them up!).
• The plastic dowel at the rear of the space derby to hold the rubber bands MUST be kept from rotating (groove out the back so the dowel can sit in it!) - do not glue it!
• Do not glue the front nose/propeller assembly into the front of the space derby.  It is pulled off to re-load new rubber bands!
• Do not glue the back dowel onto the rocket.  It is pulled off to re-load new rubber bands!
• The propeller should have the rounded shaft-end pointing into (touching) the space derby (this makes the bending of the wire easier and it reduces friction).
