West Coast Sailing offers complete spar sets for the Optimist sailboat. Each spar set includes a mast, boom, sprit, and rig pack. We stock the complete range of spar sets, from entry level spars to racing spars. Options include the Upgraded Club Spar Set, Quicksilver Spar Set, BlackGold Spar Set (with 40mm Boom), Blackgold Spar Set (with 45mm Boom), and BlackMax Spar Set (with 55mm Boom). See description below for full details on these spar sets.

BlackGold Spar Sets

These spar sets include 45mm mast, 27mm sprit pole (except the BlackMax set), and choice of booms. These spars are made from 7075 T6 Aerospace spec. aluminum. Each spar set includes the BlackGold rig pack, which contains two top pins, one low friction wind indicator, one spliced Vectran sprit halyard with Harken hook-in block and Harken Tie-Lite block, one four mm Vectran halyard line, and one sprit handle.

BlackGold Spar Sets available with a choice of three boom sizes:

  • BlackGold 40mm - Includes 45mm mast with 27mm sprit and a 40mm boom, a stiff and lightweight boom, which comes with a bridle and suitable for the majority of sailors.
  • BlackGold 45mm - Includes 45mm mast with 27mm sprit and a 45mm boom. The 45mm "power" boom is a stiffer boom that creates more tension on the leech for the heavier sailor.
  • BlackMax 55mm - Includes 55mm mast with 29mm sprit and a 55mm boom. The ultra-stiff (and yet lightweight) 55mm boom can be used without a bridle. This enables the larger sailor to jump across the boat and not too far aft while tacking. Set includes a 29mm sprit pole.
