Layout and boarding ease aside, it’s interesting to note that the shorter, narrower Chaparral (20 feet 6 inches by 7 feet 6 inches) and the longer, beamier Sea-Doo offer almost identical passenger space forward of their platforms. I measured the Sea-Doo as having a 42-inch-long bow cockpit and 90-inch-long main cockpit and the Chaparral a 45-inch-long bow cockpit and 90-inch main cockpit. The big differences are aft of the cockpit. The jet engine’s small size grants Sea-Doo a three-foot-long swim platform, with padded backrests for seating when not under way, and a large stowage locker built into the platform. By contrast, Chaparral takes up nearly the same three feet in sun pad length, followed by a smaller, 20-inch-long platform.
