Antrim 27 Association Carbon Fiber Mast

Carbon Fiber Mast

Features

Jim Antrim designed. Built

~90#'s including all rigging. One Design Class Legal - Completely backward compatible with Ballenger rig including use of aluminum boom and vang and class sails.

Aluminum luff track with Spinlock sail feeder. carbon one piece spreaders

Ronstan Sealoc Calibrated Turnbuckles allow for precise adjustment. Ronstan turning block for spinnaker halyard to reduce chafe.

Lightweight ultra strong no stretch 5mm Navtec Dyform discontinous standing rigging. Filament Wound and cured under high pressure and temperature.

Clear coated for low maintenance. No permanent or running backstays and checkstays to deal with when jibing. Completely adjustable mast bend with no extra wires locking in the shape.

Carbon fiber is strong, light, and reliable - an ideal spar material.

Carbon fiber racing spars routinely survive the kind of "wipeouts" that crumple aluminum masts. They play an important role in the safety of the sport.

The stiffness to weight ratio of carbon spars is more than twice that of comparable aluminum spars. The weight of carbon spars is about one-half the weight of aluminum spars, and carbon spars are considerably stronger. Carbon spars afford significantly increased durability and longevity. They are far more fatigue-resistant. They will not corrode, and they are easier to maintain and repair than aluminum spars.

Next to increasing draft, reducing rig weight is the most immediate and effective way to increase performance.
