When two boats share the same hull type — in this case both the Campion 550i BR 2009 and the Campion 800i SC 2009 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Campion 800i SC 2009 measures 28,0 feet overall (2009), giving it roughly 26,0 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 800i SC 2009 tips the scales at 4 855 lbs — 1 969 lbs less than the Campion 550i BR 2009 at 2 886 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 460 hp, the Campion 800i SC 2009 has a 140-hp advantage over the Campion 550i BR 2009's 320-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 800i SC 2009 carries 63 gallons versus 29 gallons in the Campion 550i BR 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
