When two boats share the same hull type — in this case both the Campion Allante 535 BR 2010 and the Campion Explorer 542 SC 2011 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Campion Allante 535 BR 2010 at 17,8 ft versus Campion Explorer 542 SC 2011 at 19,5 ft. Weight tells a clearer story for trailering families: the Campion Explorer 542 SC 2011 tips the scales at 199 lbs — 181 lbs less than the Campion Allante 535 BR 2010 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 — 150 hp for the Campion Allante 535 BR 2010 and 150 hp for the Campion Explorer 542 SC 2011. 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. Fuel capacity breaks the other way: the Campion Explorer 542 SC 2011 carries 47 gallons versus 24 gallons in the Campion Allante 535 BR 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 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.
