When two boats share the same hull type — in this case both the Campion 602i SC 2009 and the Campion Allante 505 BR 2010 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 602i SC 2009 measures 23,0 feet overall (2009), giving it roughly 6,4 additional feet of deck space compared to the Campion Allante 505 BR 2010 at 16,6 feet (2010). At 39 lbs and 128 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 320 hp, the Campion 602i SC 2009 has a 195-hp advantage over the Campion Allante 505 BR 2010'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 Allante 505 BR 2010 carries 24 gallons versus 6 gallons in the Campion 602i SC 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 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.
Bottom line: The Campion 602i SC 2009 at 23,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Campion Allante 505 BR 2010 at 16,6 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
