Mast Specifications
We manufacture our own mast sections which have been designed to optimize stiffness to weight ratios while retaining areo-dynamic properties. All OZ SPAR sections incorporate Harken luff car tracks with integral bolt rope groove. The HM245 section features dual trisail tracks for ease of trisail hoist without removal of the mainsail. Material is exclusively 6061-T6 aluminium alloy.
