When two boats share the same hull type — in this case both the Starcraft Marine 2100 2010 and the Starcraft Marine Limited 2119 I/O 2012 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?

On paper these two are close siblings in the size department — Starcraft Marine 2100 2010 at 20,8 ft versus Starcraft Marine Limited 2119 I/O 2012 at 21,3 ft. Weight tells a clearer story for trailering families: the Starcraft Marine 2100 2010 tips the scales at 1 715 lbs — 1 694 lbs more than the Starcraft Marine Limited 2119 I/O 2012 at 21 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 300 hp, the Starcraft Marine Limited 2119 I/O 2012 has a 50-hp advantage over the Starcraft Marine 2100 2010's 250-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 2100 2010 carries 52 gallons versus 45 gallons in the Starcraft Marine Limited 2119 I/O 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 1 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
