Matching a deep vee Campion Allante 505ob 2012 against a modified vee Campion Allante 595i BR 2010 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.
Size is the most obvious dividing line here. The Campion Allante 595i BR 2010 measures 21,5 feet overall (2010), giving it roughly 4,9 additional feet of deck space compared to the Campion Allante 505ob 2012 at 16,6 feet (2012). At 128 lbs and 34 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 320 hp, the Campion Allante 595i BR 2010 has a 195-hp advantage over the Campion Allante 505ob 2012's 125-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Campion Allante 595i BR 2010 carries 47 gallons versus 24 gallons in the Campion Allante 505ob 2012. 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 595i BR 2010 is rated for 8 passengers, while the Campion Allante 505ob 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 595i BR 2010 could be the deciding factor.
Bottom line: Choose the Campion Allante 595i BR 2010 if your priority is putting more people on the water — it handles 8 passengers and at 21,5 ft it has the deck room to back that rating up comfortably. The Campion Allante 505ob 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
