When two boats share the same hull type — in this case both the Campion 552i SC 2009 and the Campion Allante 595i BR 2010 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 Allante 595i BR 2010 measures 21,5 feet overall (2010), giving it roughly 19,5 additional feet of deck space compared to the Campion 552i SC 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Campion 552i SC 2009 tips the scales at 3 171 lbs — 3 137 lbs more than the Campion Allante 595i BR 2010 at 34 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 Allante 595i BR 2010 has a 95-hp advantage over the Campion 552i SC 2009's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 47 gal and 47 gal — so range won't be a tiebreaker here.
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 552i SC 2009 caps at 7. 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 552i SC 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
