When two boats share the same hull type — in this case both the Pursuit C 310 2010 and the Pursuit OS 315 2010 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?

On paper these two are close siblings in the size department — Pursuit C 310 2010 at 31,2 ft versus Pursuit OS 315 2010 at 32,7 ft. Weight tells a clearer story for trailering families: the Pursuit OS 315 2010 tips the scales at 11 015 lbs — 10 929 lbs less than the Pursuit C 310 2010 at 86 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 600 hp, the Pursuit OS 315 2010 has a 100-hp advantage over the Pursuit C 310 2010'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 OS 315 2010 carries 284 gallons versus 26 gallons in the Pursuit C 310 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
