This is Brian Kelly's guide to tuning the "S" Boat, which came from the Quantum Sail Design Group. It is not copyrighted, as Brian wanted this widely shared. Brian was a top-notch sailmaker, whose loft was part of the Quantum group, and was an avid "S" Class sailor. Brian is rumored to have singlehandedly won races in his S-Boat Eaglet, S57, on a number of occasions over the decades that he sailed. Brian won an enormous number of races during his many years racing in the "S" Class and was widely respected. Brian Kelly was inducted into the S Class Hall of Fame posthumously in 2011.
