The Starcraft Marine Limited IO 2321 RE I/O 2013 is a modified-V design and the Starcraft Marine Starliner 256 2011 is a pontoon 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 - Starcraft Marine Limited IO 2321 RE I/O 2013 at 23,3 ft versus Starcraft Marine Starliner 256 2011 at 25,3 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Starliner 256 2011 tips the scales at 2 600 lbs - 300 lbs less than the Starcraft Marine Limited IO 2321 RE I/O 2013 at 2 300 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.
The power gap is worth calling out. Rated to 320 hp, the Starcraft Marine Limited IO 2321 RE I/O 2013 has a 120-hp advantage over the Starcraft Marine Starliner 256 2011's 200-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Starcraft Marine Limited IO 2321 RE I/O 2013 carries 45 gallons versus 30 gallons in the Starcraft Marine Starliner 256 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Starcraft Marine Starliner 256 2011 is rated for 14 passengers, while the Starcraft Marine Limited IO 2321 RE I/O 2013 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Starliner 256 2011 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Starliner 256 2011 if your priority is putting more people on the water - it handles 14 passengers and at 25,3 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Limited IO 2321 RE I/O 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
