The Crownline 21 SS 2011 is a modified-V design and the Crownline 350 CR 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.

Size is the most obvious dividing line here. The Crownline 350 CR 2013 measures 36,0 feet overall (2013), giving it roughly 15,2 additional feet of deck space compared to the Crownline 21 SS 2011 at 20,8 feet (2011). Weight tells a clearer story for trailering families: the Crownline 350 CR 2013 tips the scales at 16 500 lbs - 12 800 lbs less than the Crownline 21 SS 2011 at 3 700 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.

The power gap is worth calling out. Rated to 860 hp, the Crownline 350 CR 2013 has a 540-hp advantage over the Crownline 21 SS 2011's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crownline 350 CR 2013 carries 193 gallons versus 41 gallons in the Crownline 21 SS 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 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.
