The Campion 602b SC 2006 vs Campion S 505 BR OB 2005 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 S 505 BR OB 2005 measures 16,0 feet overall (2005), giving it roughly 14,0 additional feet of deck space compared to the Campion 602b SC 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Campion 602b SC 2006 tips the scales at 247 lbs — 119 lbs more than the Campion S 505 BR OB 2005 at 128 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 602b SC 2006 has a 100-hp advantage over the Campion S 505 BR OB 2005's 125-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 S 505 BR OB 2005 carries 19 gallons versus 6 gallons in the Campion 602b SC 2006. 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 602b SC 2006 is rated for 7 passengers, while the Campion S 505 BR OB 2005 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 602b SC 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 505 BR OB 2005 comes in at 1 lbs per hp versus 1 lbs per hp for the Campion 602b SC 2006. 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.
