The Eliminator 22 ft. Daytona 2013 is a catamaran design and the Eliminator 340 Eagle XP 2011 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 340 Eagle XP 2011 measures 33,9 feet overall (2011), giving it roughly 11,8 additional feet of deck space compared to the Eliminator 22 ft. Daytona 2013 at 22,2 feet (2013). Weight tells a clearer story for trailering families: the Eliminator 340 Eagle XP 2011 tips the scales at 7 600 lbs - 4 100 lbs less than the Eliminator 22 ft. Daytona 2013 at 3 500 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.
For family outings this is probably the sharpest distinction between the two. The Eliminator 340 Eagle XP 2011 is rated for 6 passengers, while the Eliminator 22 ft. Daytona 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Eliminator 340 Eagle XP 2011 could be the deciding factor.
Bottom line: Choose the Eliminator 340 Eagle XP 2011 if your priority is putting more people on the water - it handles 6 passengers and at 33,9 ft it has the deck room to back that rating up comfortably. The Eliminator 22 ft. Daytona 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
