The Eliminator 280 Eagle XP 2009 is a modified-V design and the Eliminator 30 ft. Daytona 2013 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 280 Eagle XP 2009 at 28,3 ft versus Eliminator 30 ft. Daytona 2013 at 29,8 ft. Weight tells a clearer story for trailering families: the Eliminator 30 ft. Daytona 2013 tips the scales at 6 800 lbs - 2 000 lbs less than the Eliminator 280 Eagle XP 2009 at 4 800 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 2009 and Eliminator 30 ft. Daytona 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
