The Pursuit C 340 2007 vs Pursuit OS 345 2010 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.

On paper these two are close siblings in the size department - Pursuit C 340 2007 at 34,0 ft versus Pursuit OS 345 2010 at 36,3 ft. Weight tells a clearer story for trailering families: the Pursuit OS 345 2010 tips the scales at 15 000 lbs - 5 700 lbs less than the Pursuit C 340 2007 at 9 300 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 2010 has a 200-hp advantage over the Pursuit C 340 2007's 500-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 2007 carries 375 gallons versus 340 gallons in the Pursuit OS 345 2010. 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 2010 is rated for 11 passengers, while the Pursuit C 340 2007 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Pursuit OS 345 2010 could be the deciding factor.
