The Campion 542 SC 2007 vs Campion Allante 505ob 2013 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 2007 at 19,0 ft versus Campion Allante 505ob 2013 at 16,6 ft. At 199 lbs and 139 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 150 hp, the Campion 542 SC 2007 has a 25-hp advantage over the Campion Allante 505ob 2013'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 542 SC 2007 carries 53 gallons versus 24 gallons in the Campion Allante 505ob 2013. 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 2007 is rated for 7 passengers, while the Campion Allante 505ob 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion 542 SC 2007 could be the deciding factor.
Bottom line: Choose the Campion 542 SC 2007 if your priority is putting more people on the water — it handles 7 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Campion Allante 505ob 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
