When two boats share the same hull type — in this case both the Campion Allante 595 OB BR 2010 and the Campion Allante 705i 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?

Size is the most obvious dividing line here. The Campion Allante 705i SC 2011 measures 26,2 feet overall (2011), giving it roughly 5,2 additional feet of deck space compared to the Campion Allante 595 OB BR 2010 at 21,0 feet (2010). Weight tells a clearer story for trailering families: the Campion Allante 595 OB BR 2010 tips the scales at 2 346 lbs — 1 891 lbs more than the Campion Allante 705i SC 2011 at 455 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 — 300 hp for the Campion Allante 595 OB BR 2010 and 320 hp for the Campion Allante 705i 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 Allante 705i SC 2011 carries 69 gallons versus 47 gallons in the Campion Allante 595 OB BR 2010. 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 Allante 705i SC 2011 is rated for 9 passengers, while the Campion Allante 595 OB BR 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Campion Allante 705i SC 2011 could be the deciding factor.
