When two boats share the same hull type — in this case both the Starcraft Marine 12 SL 2011 and the Starcraft Marine 1900 C 2010 are modified vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Starcraft Marine 1900 C 2010 measures 19,0 feet overall (2010), giving it roughly 7,3 additional feet of deck space compared to the Starcraft Marine 12 SL 2011 at 11,8 feet (2011). Weight tells a clearer story for trailering families: the Starcraft Marine 1900 C 2010 tips the scales at 2 718 lbs — 2 606 lbs less than the Starcraft Marine 12 SL 2011 at 112 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 200 hp, the Starcraft Marine 1900 C 2010 has a 190-hp advantage over the Starcraft Marine 12 SL 2011's 10-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 12 SL 2011 carries 23 gallons versus 5 gallons in the Starcraft Marine 1900 C 2010. 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 1900 C 2010 is rated for 11 passengers, while the Starcraft Marine 12 SL 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine 1900 C 2010 could be the deciding factor.
Bottom line: Choose the Starcraft Marine 1900 C 2010 if your priority is putting more people on the water — it handles 11 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Starcraft Marine 12 SL 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
