Make A Toy Catamaran

Step 14 Tension the Boom String

   Depending on the amount of wind, you will want to have the boom string at different tensions. Tighter for more wind and looser for less wind. Drill a hole in the block of wood that attaches the boom to the mast, it needs to be at a 45 degree angle so it goes in one side and comes out the other (picture #1). Insert the end of the boom string that is not tied down through the hole you just created. Tie a loop AFTER the string is through the hole. Pull the string tight and mark where a screw should be placed so that the loop can go around it. Attach a screw at that mark and at a place about 1/2 inch or so closer to the mast.
   If you don't want to adjust the tension then just tie off the boom string at the end of the boom.
