The Eliminator 210 Eagle XP 2011 is a modified-V design and the Eliminator 30 ft. Daytona 2009 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.
Size is the most obvious dividing line here. The Eliminator 30 ft. Daytona 2009 measures 29,8 feet overall (2009), giving it roughly 8,7 additional feet of deck space compared to the Eliminator 210 Eagle XP 2011 at 21,2 feet (2011). Weight tells a clearer story for trailering families: the Eliminator 30 ft. Daytona 2009 tips the scales at 6 800 lbs - 3 900 lbs less than the Eliminator 210 Eagle XP 2011 at 2 900 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 30 ft. Daytona 2009 at 29,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Eliminator 210 Eagle XP 2011 at 21,2 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.
