The PlayCraft Power Deck Xtreme 260 SXi 2010 is a planing design and the PlayCraft Sunfish Series 2010 is a pontoon 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 - PlayCraft Power Deck Xtreme 260 SXi 2010 at 26,0 ft versus PlayCraft Sunfish Series 2010 at 24,0 ft. Weight tells a clearer story for trailering families: the PlayCraft Power Deck Xtreme 260 SXi 2010 tips the scales at 5 500 lbs - 3 900 lbs more than the PlayCraft Sunfish Series 2010 at 1 600 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 425 hp, the PlayCraft Power Deck Xtreme 260 SXi 2010 has a 335-hp advantage over the PlayCraft Sunfish Series 2010's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the PlayCraft Power Deck Xtreme 260 SXi 2010 carries 85 gallons versus 66 gallons in the PlayCraft Sunfish Series 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 PlayCraft Power Deck Xtreme 260 SXi 2010 is rated for 12 passengers, while the PlayCraft Sunfish Series 2010 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the PlayCraft Power Deck Xtreme 260 SXi 2010 could be the deciding factor.
Bottom line: Choose the PlayCraft Power Deck Xtreme 260 SXi 2010 if your priority is putting more people on the water - it handles 12 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The PlayCraft Sunfish Series 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
