Quantum J/70 Class Sails

J/70 Sail Development by Quantum Sail Design Group  

Quantum Sail Design Group is an acknowledged leader in advanced sail making technology and sail development. These tools, combined with top sail designers, have led to Quantum’s dominance in many J boat classes. For these reasons, Quantum was chosen by J Boats to be one of the lead sail developers for the new J/70.

The J/70 sail designs feature Quantum's high-quality sail construction details including the best sailcloth and large redial patches in the head and clew. 

For the class asymmetrical, precise modeling techniques were used to fine-tune the size and geometry of the sail to maximize performance. The sail was also evaluated on its versatility; with one class sail, the ability to adjust to different wind speeds and angles is essential.
