When two boats share the same hull type — in this case both the Pursuit C 310 2011 and the Pursuit OS 255 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?

Size is the most obvious dividing line here. The Pursuit C 310 2011 measures 31,2 feet overall (2011), giving it roughly 3,9 additional feet of deck space compared to the Pursuit OS 255 2010 at 27,3 feet (2010). At 86 lbs and 61 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 600 hp, the Pursuit C 310 2011 has a 250-hp advantage over the Pursuit OS 255 2010's 350-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 310 2011 carries 26 gallons versus 13 gallons in the Pursuit OS 255 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 C 310 2011 is rated for 9 passengers, while the Pursuit OS 255 2010 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 310 2011 could be the deciding factor.
