PACK 317 

Raingutter Regatta 2019

How it Runs


Rules for Boat Construction

The Raingutter Regatta competition will take place at the April 12th Pack meeting at Patterson Elementary School.

The rules for the Regatta are fairly simple. Scouts build boats from the kits handed out at a previous Pack Meeting – please review the “Pack 317 Rules for Boat Construction” outlined below. On race day, each Scout Rank will run double elimination races and, with the exception of Lion Scouts, the Top 2 finishers from each Rank will advance to the Pack Finals.

Scouts should plan on arriving early to check in their boats, go through technical inspection and familiarize themselves with the race courses.  Check-in time will be announced soon.

At check-in, the Coast Guard will inspect all boats for technical compliance. Once boats are inspected and checked in, they are deemed to be compliant and race ready.  Boats will then be placed into the Harbor until race time.  Prior to the first racing heat, Scouts will be asked to report to the Harbor to retrieve their boat and then boats will remain between the gutters for each respective Rank until the completion of that Rank’s races.

The races will run as outlined below:

  1. Two Scouts in each Rank will race at the same time.
  2. Each boat must start with the stern (back) of the boat touching the end of the raingutter.
  3. When the starter says “Go!”, Scouts will propel their boat down the gutter by blowing on the sail only. Scouts will blow air on the boat sail through a straw to move their boat through the water. (Straws will be provided).
  4. The run will be complete when the bow of the boat touches the end of the raingutter.

Scouts may not use their face, lips, hats, nose, hands or any other part of their body to move the boat – just lung power!  Scouts should remove their cap and neckerchief prior to competing to minimize the chances of those items making contact with the boat.

Scouts may not use their hands to advance the boat.  Hands may only be used to upright an over turned boat. In the event that a Scout does accidentally advance their boat by physically touching it, they will be reminded that blowing on the sail is the only way to advance the boat.  If a Scout repeatedly advances their boat during the race by touching it, then the race will be re-run in the spirit of fair competition. Each Scout will be permitted one re-run for the duration of the competition.  In the event that multiple violations occur, the run will be disqualified and the competing boat will be scored with a win.

If a boat breaks during a race, the Scout will have 3 minutes to fix their boat as best they can.  The Scout will then be allowed to re-do their run.  Parents may help fix the boat.

Parents and spectators are asked to remain behind the starting line during the running of the races in order to allow enough space between the gutters for the Scouts to maneuver.

We will need several parents on race day to help with managing the Harbor, officiating the races, and recording the result brackets.  Please let us know prior to the race or at check-in, if you would like to be part of the Regatta Team.  Volunteer parents may be assigned to Ranks other than the Rank of their Scout(s).

Rules for Boat Construction

  1. The boat must be newly built for the current Cub Scouting year. This year’s boat is the “Raingutter Regatta Trimaran Boat Kit”.  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 decorations, decals, paint, and glue are permitted.
  2. The boat must resemble a traditional trimaran sailboat as illustrated on the front of the kit box.
  3. Overall length from bow to stern shall not exceed 7.00 inches, nor be shorter than 6.50 inches.
  4. The mast must be upright and can be no taller than 6.50 inches from the deck surface. The mast shall be placed in the hull’s mast holder and shall remain in one piece.  All boats shall have a mast.
  5. The sail supplied in the kit must be used and may not be larger than the material supplied.  The sail should look like the sail on the cover of the kit box.  It may not be folded, cupped, or used to make any shape other than that of a traditional sail. For example, no cone, cup, box, “V”, rectangle, cylinder, L-shape, or other design may be used. Sails shall not touch the Hull or Outriggers.
  6. The bottom of the sail must be at least ½” above the top surface of the boat.  This is to keep the sails from getting caught on the tops of the rain gutters or dipping into the water. Boats with sails lower than 1/2“ inch above the boat deck will not be permitted to compete.
  7. The sail should be glued or taped to the mast.  Scouts may elect to tie a string to each lower corner of the sail and then affix the other end of the string to the boat. The plastic hull has locations at the back of the hull specifically for tying off the back of the sail.  This will keep the sail from spinning.

  1. The plastic hull shall be used as supplied in the kit in an unmodified state other than painting or decorating.   While some photos & videos on the internet show boats with cut up plastic hulls, Pack 317 has chosen to use the hulls in an intact, unmodified state so as to provide for an equal playing field.
  2. The outriggers can be shaped to help the boat glide better through the water.  Flat bottoms keep the boat level in the water.  “V” shaped outrigger hulls tend to list to one side and make the boat more challenging to race.  The boats perform better when there is a slight weight bias toward the stern rather than toward the bow.
  3. No bumpers or other devices may be added to the boat for stabilization.
  4. Scouts are encouraged to paint their boats.  This not only looks great, but it keeps the wooden outriggers from getting water logged.  Please use paints that are not water soluble.  And please make sure the paint is dry before bringing the boat to the race event.    
  5. 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.
  6. There will be no min/max weight limit, however, heavier is not better (opposite from Pinewood Derby rules).
  7. You can add material and items to the boats, but keep in mind that lighter boats will generally be faster.
  8. It is suggested that Scouts try out their boats in a sink or bathtub at home prior to race day to ensure that the boat is stable.
