The Outerlimits 43 SV 2012 is a deep-V design and the Outerlimits 48 Cat 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.
Size is the most obvious dividing line here. The Outerlimits 48 Cat 2013 measures 48,4 feet overall (2013), giving it roughly 5,0 additional feet of deck space compared to the Outerlimits 43 SV 2012 at 43,4 feet (2012). Weight tells a clearer story for trailering families: the Outerlimits 48 Cat 2013 tips the scales at 10 150 lbs - 1 150 lbs less than the Outerlimits 43 SV 2012 at 9 000 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 Outerlimits 48 Cat 2013 is rated for 14 passengers, while the Outerlimits 43 SV 2012 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Outerlimits 48 Cat 2013 could be the deciding factor.
Bottom line: Choose the Outerlimits 48 Cat 2013 if your priority is putting more people on the water - it handles 14 passengers and at 48,4 ft it has the deck room to back that rating up comfortably. The Outerlimits 43 SV 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
