The Campion Infinyte i3 2012 is a tunnel hull design and the Campion S 565i BR 2008 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Campion S 565i BR 2008 measures 19,0 feet overall (2008), giving it roughly 7,0 additional feet of deck space compared to the Campion Infinyte i3 2012 at 12,0 feet (2012). Weight tells a clearer story for trailering families: the Campion S 565i BR 2008 tips the scales at 1 900 lbs - 1 720 lbs less than the Campion Infinyte i3 2012 at 180 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 175 hp, the Campion S 565i BR 2008 has a 165-hp advantage over the Campion Infinyte i3 2012's 10-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Campion S 565i BR 2008 is rated for 8 passengers, while the Campion Infinyte i3 2012 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion S 565i BR 2008 could be the deciding factor.
Bottom line: Choose the Campion S 565i BR 2008 if your priority is putting more people on the water - it handles 8 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Campion Infinyte i3 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
