The Pursuit C 310 2007 vs Pursuit OS 345 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Pursuit OS 345 2013 measures 36,3 feet overall (2013), giving it roughly 5,3 additional feet of deck space compared to the Pursuit C 310 2007 at 31,0 feet (2007). Weight tells a clearer story for trailering families: the Pursuit OS 345 2013 tips the scales at 15 950 lbs - 7 050 lbs less than the Pursuit C 310 2007 at 8 900 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 OS 345 2013 has a 100-hp advantage over the Pursuit C 310 2007's 600-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 OS 345 2013 carries 340 gallons versus 260 gallons in the Pursuit C 310 2007. 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 OS 345 2013 is rated for 11 passengers, while the Pursuit C 310 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pursuit OS 345 2013 could be the deciding factor.
