The Campion 542 SC 2006 vs Campion 545i SS 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.

On paper these two are close siblings in the size department — Campion 542 SC 2006 at 18,0 ft versus Campion 545i SS 2005 at 18,0 ft. Weight tells a clearer story for trailering families: the Campion 542 SC 2006 tips the scales at 179 lbs — 155 lbs more than the Campion 545i SS 2005 at 24 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 250 hp, the Campion 545i SS 2005 has a 100-hp advantage over the Campion 542 SC 2006's 150-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 542 SC 2006 carries 53 gallons versus 29 gallons in the Campion 545i SS 2005. 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 542 SC 2006 is rated for 7 passengers, while the Campion 545i SS 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 542 SC 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Campion 545i SS 2005 comes in at 0 lbs per hp versus 1 lbs per hp for the Campion 542 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.
