Matching a modified vee Campion 485 BR 2009 against a deep vee Campion Allante 505i 2013 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 485 BR 2009 at 16,0 ft versus Campion Allante 505i 2013 at 17,1 ft. Weight tells a clearer story for trailering families: the Campion Allante 505i 2013 tips the scales at 1 978 lbs — 1 884 lbs less than the Campion 485 BR 2009 at 94 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 125 hp, the Campion Allante 505i 2013 has a 35-hp advantage over the Campion 485 BR 2009's 90-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 505i 2013 carries 24 gallons versus 13 gallons in the Campion 485 BR 2009. 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 505i 2013 is rated for 6 passengers, while the Campion 485 BR 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 505i 2013 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Campion 485 BR 2009 comes in at 1 lbs per hp versus 16 lbs per hp for the Campion Allante 505i 2013. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Bottom line: Choose the Campion Allante 505i 2013 if your priority is putting more people on the water — it handles 6 passengers and at 17,1 ft it has the deck room to back that rating up comfortably. The Campion 485 BR 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
