When two boats share the same hull type — in this case both the Pursuit OS 315 2011 and the Pursuit S 310 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?

On paper these two are close siblings in the size department — Pursuit OS 315 2011 at 32,7 ft versus Pursuit S 310 2013 at 31,2 ft. Weight tells a clearer story for trailering families: the Pursuit OS 315 2011 tips the scales at 11 015 lbs — 10 126 lbs more than the Pursuit S 310 2013 at 889 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.

Both boats share a closely matched power ceiling — 600 hp for the Pursuit OS 315 2011 and 600 hp for the Pursuit S 310 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Pursuit OS 315 2011 carries 284 gallons versus 26 gallons in the Pursuit S 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.
