Both the Starcraft Marine 191 OB 2008 and the Starcraft Marine Limited IO 2119 RE I/O 2013 are modified-V designs, the first built in aluminium and the second in fibreglass, so 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 191 OB 2008 at 21,0 ft versus Starcraft Marine Limited IO 2119 RE I/O 2013 at 21,3 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Limited IO 2119 RE I/O 2013 tips the scales at 2 100 lbs - 403 lbs less than the Starcraft Marine 191 OB 2008 at 1 697 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 IO 2119 RE I/O 2013 has a 150-hp advantage over the Starcraft Marine 191 OB 2008'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 Limited IO 2119 RE I/O 2013 carries 45 gallons versus 34 gallons in the Starcraft Marine 191 OB 2008. 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 Limited IO 2119 RE I/O 2013 is rated for 10 passengers, while the Starcraft Marine 191 OB 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Limited IO 2119 RE I/O 2013 could be the deciding factor.
