The Campion 622 Walkaround 2007 vs Campion Allante 705i SC 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Campion Allante 705i SC 2011 measures 26,2 feet overall (2011), giving it roughly 3,2 additional feet of deck space compared to the Campion 622 Walkaround 2007 at 23,0 feet (2007). Weight tells a clearer story for trailering families: the Campion Allante 705i SC 2011 tips the scales at 455 lbs — 193 lbs less than the Campion 622 Walkaround 2007 at 262 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 705i SC 2011 has a 95-hp advantage over the Campion 622 Walkaround 2007'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 — 71 gal and 69 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Campion Allante 705i SC 2011 is rated for 9 passengers, while the Campion 622 Walkaround 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 705i SC 2011 could be the deciding factor.
Bottom line: Choose the Campion Allante 705i SC 2011 if your priority is putting more people on the water — it handles 9 passengers and at 26,2 ft it has the deck room to back that rating up comfortably. The Campion 622 Walkaround 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
