Both the EdgeWater 158CC 2011 and the EdgeWater 220IS 2013 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 220IS 2013 measures 22,0 feet overall (2013), giving it roughly 6,9 additional feet of deck space compared to the EdgeWater 158CC 2011 at 15,1 feet (2011). Weight tells a clearer story for trailering families: the EdgeWater 220IS 2013 tips the scales at 2 500 lbs - 1 300 lbs less than the EdgeWater 158CC 2011 at 1 200 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 250 hp, the EdgeWater 220IS 2013 has a 160-hp advantage over the EdgeWater 158CC 2011's 90-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 220IS 2013 carries 65 gallons versus 18 gallons in the EdgeWater 158CC 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 220IS 2013 is rated for 6 passengers, while the EdgeWater 158CC 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 220IS 2013 could be the deciding factor.
Bottom line: Choose the EdgeWater 220IS 2013 if your priority is putting more people on the water - it handles 6 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The EdgeWater 158CC 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
