When two boats share the same hull type — in this case both the Pursuit C 340 2008 and the Pursuit OS 255 2008 are deep 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 Pursuit C 340 2008 measures 34,0 feet overall (2008), giving it roughly 7,0 additional feet of deck space compared to the Pursuit OS 255 2008 at 27,0 feet (2008). Weight tells a clearer story for trailering families: the Pursuit OS 255 2008 tips the scales at 548 lbs — 455 lbs less than the Pursuit C 340 2008 at 93 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 700 hp, the Pursuit C 340 2008 has a 400-hp advantage over the Pursuit OS 255 2008's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Pursuit C 340 2008 carries 375 gallons versus 13 gallons in the Pursuit OS 255 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 Pursuit C 340 2008 is rated for 10 passengers, while the Pursuit OS 255 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pursuit C 340 2008 could be the deciding factor.
