The Starcraft Marine Crossover 220 SCX OB 2012 is a tri-hull design and the Starcraft Marine Stardeck 236 Cruise 2013 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 Crossover 220 SCX OB 2012 at 21,6 ft versus Starcraft Marine Stardeck 236 Cruise 2013 at 23,8 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Crossover 220 SCX OB 2012 tips the scales at 3 500 lbs - 1 300 lbs more than the Starcraft Marine Stardeck 236 Cruise 2013 at 2 200 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 250 hp, the Starcraft Marine Crossover 220 SCX OB 2012 has a 100-hp advantage over the Starcraft Marine Stardeck 236 Cruise 2013's 150-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 Crossover 220 SCX OB 2012 carries 75 gallons versus 30 gallons in the Starcraft Marine Stardeck 236 Cruise 2013. 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 Crossover 220 SCX OB 2012 is rated for 13 passengers, while the Starcraft Marine Stardeck 236 Cruise 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 Crossover 220 SCX OB 2012 could be the deciding factor.
Bottom line: Choose the Starcraft Marine Crossover 220 SCX OB 2012 if your priority is putting more people on the water - it handles 13 passengers and at 21,6 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Stardeck 236 Cruise 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.
