Matching a modified vee Campion 550i BR 2009 against a deep vee Campion Allante 485 Forster 2012 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 485 Forster 2012 measures 16,1 feet overall (2012), giving it roughly 14,1 additional feet of deck space compared to the Campion 550i BR 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Campion 550i BR 2009 tips the scales at 2 886 lbs — 2 792 lbs more than the Campion Allante 485 Forster 2012 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 320 hp, the Campion 550i BR 2009 has a 230-hp advantage over the Campion Allante 485 Forster 2012'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 550i BR 2009 carries 29 gallons versus 13 gallons in the Campion Allante 485 Forster 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 550i BR 2009 is rated for 7 passengers, while the Campion Allante 485 Forster 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 550i BR 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Campion Allante 485 Forster 2012 comes in at 1 lbs per hp versus 9 lbs per hp for the Campion 550i BR 2009. 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 550i BR 2009 if your priority is putting more people on the water — it handles 7 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Campion Allante 485 Forster 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
