The Parker Boats 2520 XLD Sport Cabin 2013 is a modified-V design and the Parker Boats 2801 Center Console 2013 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Parker Boats 2520 XLD Sport Cabin 2013 at 25,3 ft versus Parker Boats 2801 Center Console 2013 at 27,3 ft. Weight tells a clearer story for trailering families: the Parker Boats 2520 XLD Sport Cabin 2013 tips the scales at 5 800 lbs - 800 lbs more than the Parker Boats 2801 Center Console 2013 at 5 000 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 Parker Boats 2801 Center Console 2013 has a 100-hp advantage over the Parker Boats 2520 XLD Sport Cabin 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 Parker Boats 2801 Center Console 2013 carries 232 gallons versus 179 gallons in the Parker Boats 2520 XLD Sport Cabin 2013. 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 Parker Boats 2801 Center Console 2013 is rated for 8 passengers, while the Parker Boats 2520 XLD Sport Cabin 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Parker Boats 2801 Center Console 2013 could be the deciding factor.
Bottom line: Choose the Parker Boats 2801 Center Console 2013 if your priority is putting more people on the water - it handles 8 passengers and at 27,3 ft it has the deck room to back that rating up comfortably. The Parker Boats 2520 XLD Sport Cabin 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
