The 210 Challenger S we tested is the middle trim level for the series. Unlike the base 210 (priced less than $30,000), it offers a choice of twin engines or the single direct-injected, supercharged 255 hp Rotax powering our test boat. Other S-version niceties include snap-in carpet, a cockpit table and a satellite-ready stereo with USB-device control. Upgrading to the top-line SE version nets you twin engines, super-cool Transat reclining seats on the swim platform and more. A tandem-axle trailer with swing-away tongue is standard.
