When two boats share the same hull type — in this case both the Starcraft Marine 1700 OB Fish 2008 and the Starcraft Marine Limited 2321 I/O 2012 are modified vee designs with fiberglass 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 Limited 2321 I/O 2012 measures 23,3 feet overall (2012), giving it roughly 7,3 additional feet of deck space compared to the Starcraft Marine 1700 OB Fish 2008 at 16,0 feet (2008). Weight tells a clearer story for trailering families: the Starcraft Marine 1700 OB Fish 2008 tips the scales at 152 lbs — 129 lbs more than the Starcraft Marine Limited 2321 I/O 2012 at 23 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 2321 I/O 2012 has a 190-hp advantage over the Starcraft Marine 1700 OB Fish 2008's 130-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 2321 I/O 2012 carries 45 gallons versus 23 gallons in the Starcraft Marine 1700 OB Fish 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 2321 I/O 2012 is rated for 12 passengers, while the Starcraft Marine 1700 OB Fish 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 2321 I/O 2012 could be the deciding factor.
