When two boats share the same hull type — in this case both the Pursuit C 310 2013 and the Pursuit OS 285 2013 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 310 2013 measures 31,2 feet overall (2013), giving it roughly 28,2 additional feet of deck space compared to the Pursuit OS 285 2013 at 3,0 feet (2013). Weight tells a clearer story for trailering families: the Pursuit OS 285 2013 tips the scales at 8 865 lbs — 8 779 lbs less than the Pursuit C 310 2013 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 C 310 2013 has a 100-hp advantage over the Pursuit OS 285 2013'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 285 2013 carries 232 gallons versus 26 gallons in the Pursuit C 310 2013. 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.
