Both the EdgeWater 188CC 2013 and the EdgeWater 318CC 2011 are deep-V designs, both built in composite, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The EdgeWater 318CC 2011 measures 31,8 feet overall (2011), giving it roughly 13,2 additional feet of deck space compared to the EdgeWater 188CC 2013 at 18,7 feet (2013). Weight tells a clearer story for trailering families: the EdgeWater 318CC 2011 tips the scales at 6 500 lbs - 4 450 lbs less than the EdgeWater 188CC 2013 at 2 050 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 2011 has a 550-hp advantage over the EdgeWater 188CC 2013's 150-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 2011 carries 300 gallons versus 54 gallons in the EdgeWater 188CC 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 EdgeWater 318CC 2011 is rated for 12 passengers, while the EdgeWater 188CC 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 318CC 2011 could be the deciding factor.
