When two boats share the same hull type — in this case both the Parker Boats 2310 DV Walkaround 2008 and the Parker Boats 2320 SL Sport Cabin 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 — Parker Boats 2310 DV Walkaround 2008 at 23,0 ft versus Parker Boats 2320 SL Sport Cabin 2010 at 23,0 ft. Weight tells a clearer story for trailering families: the Parker Boats 2310 DV Walkaround 2008 tips the scales at 4 288 lbs — 4 247 lbs more than the Parker Boats 2320 SL Sport Cabin 2010 at 41 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 300 hp, the Parker Boats 2310 DV Walkaround 2008 has a 50-hp advantage over the Parker Boats 2320 SL Sport Cabin 2010's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 15 gal and 15 gal — so range won't be a tiebreaker here.
Both boats are rated for 7 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.
Bottom line: Performance buyers should lean toward the Parker Boats 2310 DV Walkaround 2008 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Parker Boats 2320 SL Sport Cabin 2010 with its 250-hp rating is the more economical daily driver.
