A custom Legacy tow boat powered by triple Mercury Racing 300XS outboards was used to establish a Guinness World Record for the largest human pyramid on water skis. The Rock Aqua Jays water ski team of Janesville, Wis., organized the August 18 attempt after a year of preparation. A total of 80 skiers in multiple four-tier pyramids traveled 300 meters on the Rock River, about twice the distance necessary to officially surpass the previous 64-skier record. Joining the Rock Aqua Jays were skiers from the Aquanuts team from Twin Lakes, Wis., and the Webfooters from Fremont, Wis. A pair of boats pulled the skiers from the dock area, but the lead boat released when they reached open water and the record run was accomplished behind a single boat. The skiers initially broke the existing record with a 70-skier pyramid, then added 10 more individuals on a subsequent run to establish the 80-skier record. Guinness officially confirmed the record.
