The Crownline 266 SC 2010 is a modified-V design and the Crownline E6 EC 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 - Crownline 266 SC 2010 at 26,5 ft versus Crownline E6 EC 2013 at 26,3 ft. Weight tells a clearer story for trailering families: the Crownline 266 SC 2010 tips the scales at 6 200 lbs - 500 lbs more than the Crownline E6 EC 2013 at 5 700 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 - 425 hp for the Crownline 266 SC 2010 and 430 hp for the Crownline E6 EC 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 Crownline 266 SC 2010 carries 62 gallons versus 55 gallons in the Crownline E6 EC 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 Crownline 266 SC 2010 is rated for 10 passengers, while the Crownline E6 EC 2013 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crownline 266 SC 2010 could be the deciding factor.
