About the Company Name

Single Sail Software –  In the bygone era of wind power the cat boat served as a simple to sail reliable work boat. Cat boats are powered by one large sail to make the most of the wind available and have a wide berth for stability in rough waters. Those same ideas inspire the design of my software: elegantly simple with practical operation and stability.
