The Campion S 505i BR 2008 vs Campion S 535 O/B BR 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 S 505i BR 2008 at 16,0 ft versus Campion S 535 O/B BR 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Campion S 505i BR 2008 tips the scales at 1 974 lbs — 1 956 lbs more than the Campion S 535 O/B BR 2006 at 18 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.

Both boats share a closely matched power ceiling — 135 hp for the Campion S 505i BR 2008 and 150 hp for the Campion S 535 O/B BR 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Campion S 535 O/B BR 2006 is rated for 7 passengers, while the Campion S 505i BR 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion S 535 O/B BR 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion S 535 O/B BR 2006 comes in at 0 lbs per hp versus 15 lbs per hp for the Campion S 505i BR 2008. 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.
