Stiffness-to-weight-ratio

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.

Handling

Lightweight carbon spars lower the center of gravity and reduce the pitching moment, so carbon spars substantially improve vessel stability, ease of handling, and safety.

Performance

In favorable conditions, carbon spars can carry a larger sail area for greater speed. When sails are reefed down, carbon spars improve drive through rough seas and increase stability by up to 15 percent.

Durability

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 wooden or aluminum spars.
