Matching a deep vee Campion Allante 595ob SC 2013 against a modified vee Campion Allante 645i SC 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Campion Allante 595ob SC 2013 at 21,0 ft versus Campion Allante 645i SC 2011 at 23,1 ft. Weight tells a clearer story for trailering families: the Campion Allante 645i SC 2011 tips the scales at 4 037 lbs — 1 691 lbs less than the Campion Allante 595ob SC 2013 at 2 346 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.
Both boats share a closely matched power ceiling — 300 hp for the Campion Allante 595ob SC 2013 and 320 hp for the Campion Allante 645i SC 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Campion Allante 645i SC 2011 carries 56 gallons versus 47 gallons in the Campion Allante 595ob SC 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Campion Allante 645i SC 2011 is rated for 9 passengers, while the Campion Allante 595ob SC 2013 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 645i SC 2011 could be the deciding factor.
Bottom line: Choose the Campion Allante 645i SC 2011 if your priority is putting more people on the water — it handles 9 passengers and at 23,1 ft it has the deck room to back that rating up comfortably. The Campion Allante 595ob SC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
