The Starcraft Marine 206 RE CR 2010 is a pontoon design and the Starcraft Marine Limited 2000 I/O 2011 is a modified-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 - Starcraft Marine 206 RE CR 2010 at 20,3 ft versus Starcraft Marine Limited 2000 I/O 2011 at 20,3 ft. Weight tells a clearer story for trailering families: the Starcraft Marine Limited 2000 I/O 2011 tips the scales at 2 325 lbs - 450 lbs less than the Starcraft Marine 206 RE CR 2010 at 1 875 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 260 hp, the Starcraft Marine Limited 2000 I/O 2011 has a 145-hp advantage over the Starcraft Marine 206 RE CR 2010's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Starcraft Marine Limited 2000 I/O 2011 carries 51 gallons versus 24 gallons in the Starcraft Marine 206 RE CR 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 12 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 Starcraft Marine Limited 2000 I/O 2011 and its 260-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Starcraft Marine 206 RE CR 2010 with its 115-hp rating is the more economical daily driver.
