The Eliminator 230 Eagle XP 2011 is a deep-V design and the Eliminator 280 Eagle XP 2012 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Eliminator 280 Eagle XP 2012 measures 28,3 feet overall (2012), giving it roughly 5,3 additional feet of deck space compared to the Eliminator 230 Eagle XP 2011 at 23,0 feet (2011). Weight tells a clearer story for trailering families: the Eliminator 280 Eagle XP 2012 tips the scales at 4 800 lbs - 1 400 lbs less than the Eliminator 230 Eagle XP 2011 at 3 400 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 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 Eliminator 280 Eagle XP 2012 at 28,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Eliminator 230 Eagle XP 2011 at 23,0 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.
