The Campion 580 O/B BR 2006 vs Campion 622 Walkaround 2006 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.
On paper these two are close siblings in the size department - Campion 580 O/B BR 2006 at 18,0 ft versus Campion 622 Walkaround 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Campion 622 Walkaround 2006 tips the scales at 2 620 lbs - 600 lbs less than the Campion 580 O/B BR 2006 at 2 020 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 225 hp, the Campion 622 Walkaround 2006 has a 25-hp advantage over the Campion 580 O/B BR 2006's 200-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 622 Walkaround 2006 carries 71 gallons versus 28 gallons in the Campion 580 O/B BR 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 8 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.
Bottom line: The Campion 622 Walkaround 2006 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion 580 O/B BR 2006 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
