4. Recommendations for Halyard and Sheet Sizes

   Updated November, 2007 according to Cape Cod Shipbuiling Company

   HALYARDS:	Note: All halyards may be entirely of Kevar or Spectra.
   Main Halyard	43' of 5/32" stainless 7x19 wire and 38' of 5/16" dacron line or 85' of 5/16"
   Spinnaker Halyard	78' of 5/16" line minimum
   Jib Halyard	39' of 5/32" stainless 7x19 wire and 38' of 5/16" dacron line or 79' of 1/2"
   SHEETS:
   Main Sheet	70' of 3/8" low stretch line
   Jib Sheets	(2) 30' each of 5/16" low stretch line
   Spinnaker Sheets (See Notes 1,2,3)	(2) 65' each of 3/8" dacron
   	Notes:
   	1. Separate light sheets are permitted.
   	2. Kevlar or Spectra are permitted
   	3. For heavy air the 3/8" line in Dacron will allow some stretch which helps to stabilize the spinnaker in rough conditions. Light air sheets are better as low stretch.

   Anchor Line	Minimum of 100' of 1/2" nylon required (see Section IV 9.1)
   Spinnaker Pole Lift	43' of 5/16" dacron
   Spinnaker Pole Foreguy	20' of 5/16" dacron
   Boomvang	30' of 3/8" dacron for 4:1 (8:1 is permitted)
   Spinnaker Twings	(2) 15' each of 5/16"
   Backstay Adjustment	(2) 46' each of 5/16" plus 45" of 3/8" for 8:1 system
