When two boats share the same hull type — in this case both the EdgeWater 170CC 2009 and the EdgeWater 205CX 2013 are deep vee designs with fiberglass construction — 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 205CX 2013 measures 20,5 feet overall (2013), giving it roughly 4,5 additional feet of deck space compared to the EdgeWater 170CC 2009 at 16,0 feet (2009). At 17 lbs and 28 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 225 hp, the EdgeWater 205CX 2013 has a 110-hp advantage over the EdgeWater 170CC 2009'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 EdgeWater 205CX 2013 carries 75 gallons versus 32 gallons in the EdgeWater 170CC 2009. 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 205CX 2013 is rated for 9 passengers, while the EdgeWater 170CC 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 205CX 2013 could be the deciding factor.
