Just as a point of reference, at the Championship of Champions that I sailed in last fall, ALL the boats (20 Flying Scots) were donated by club members (Dallas Corinthian). In return, the donors received significantly discounted new sails (main, jib, spin) with only 4 days of sailing on them. All the boats were set up more-or-less identically (some of the control layouts were different). Everybody raced each boat once (in every race). Rotations were made on the water, utilizing a floating dock that was towed out to the racing area each day.
