The EdgeWater 220IS 2011 is a modified-V design and the EdgeWater 318CC 2012 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 EdgeWater 318CC 2012 measures 31,8 feet overall (2012), giving it roughly 9,8 additional feet of deck space compared to the EdgeWater 220IS 2011 at 22,0 feet (2011). Weight tells a clearer story for trailering families: the EdgeWater 318CC 2012 tips the scales at 6 500 lbs - 4 100 lbs less than the EdgeWater 220IS 2011 at 2 400 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 700 hp, the EdgeWater 318CC 2012 has a 450-hp advantage over the EdgeWater 220IS 2011's 250-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the EdgeWater 318CC 2012 carries 300 gallons versus 65 gallons in the EdgeWater 220IS 2011. 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 EdgeWater 318CC 2012 is rated for 12 passengers, while the EdgeWater 220IS 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 318CC 2012 could be the deciding factor.
