The Eliminator 260 Eagle XP 2009 is a modified-V design and the Eliminator 28 ft. Daytona 2011 is a catamaran 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.
On paper these two are close siblings in the size department - Eliminator 260 Eagle XP 2009 at 26,3 ft versus Eliminator 28 ft. Daytona 2011 at 28,5 ft. Weight tells a clearer story for trailering families: the Eliminator 28 ft. Daytona 2011 tips the scales at 6 500 lbs - 2 400 lbs less than the Eliminator 260 Eagle XP 2009 at 4 100 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 28 ft. Daytona 2011 at 28,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Eliminator 260 Eagle XP 2009 at 26,3 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.
