Twenty-four feet is roughly where a racing slide stops being a garden attraction and starts pulling people across a park. Two wave lanes under palm toppers, finishing into a pool wide enough to take both at once. Ages 6 and up — the drop is steep enough that we hold that line. It runs on two 1.5 HP blowers and needs 37 × 22 ft: two feet less length than our 18 ft racers, two feet more width. Overhead clearance matters more than footprint at this height, so check for branches and service lines over the pad.
