The Optimax MkIV Spars were new in 2007. They have already one a World Title with Chris Steele at the Sardinia Worlds 2007. The MK4 boom is 45mm giving a little extra stiffness and power to the heavier sailors.
This complete set comes with a rig pack giving everything needed to set up and sail straight away.
All boom end fittings are made of high quality glass fibre filled nylon. Unlike inboard boom-end fittings from other manufacturers ours have a firm grip around the mast.This ensures that mast and boom turn together. When retrofitting an old mast with a high heel plug first make sure the total mast length will not exceed 2350 mm. Diameters given are outside tube diameters.
