The Clearwater 1800 CC 2012 is a deep-V design and the Clearwater 2000 CC 2010 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 - Clearwater 1800 CC 2012 at 17,0 ft versus Clearwater 2000 CC 2010 at 20,0 ft. Weight tells a clearer story for trailering families: the Clearwater 2000 CC 2010 tips the scales at 2 400 lbs - 550 lbs less than the Clearwater 1800 CC 2012 at 1 850 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 200 hp, the Clearwater 2000 CC 2010 has a 85-hp advantage over the Clearwater 1800 CC 2012'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 Clearwater 2000 CC 2010 carries 65 gallons versus 35 gallons in the Clearwater 1800 CC 2012. 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 Clearwater 2000 CC 2010 is rated for 8 passengers, while the Clearwater 1800 CC 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Clearwater 2000 CC 2010 could be the deciding factor.
Bottom line: Choose the Clearwater 2000 CC 2010 if your priority is putting more people on the water - it handles 8 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Clearwater 1800 CC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
