When two boats share the same hull type — in this case both the EdgeWater 205CX 2010 and the EdgeWater 210IS 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 210IS 2013 measures 21,7 feet overall (2013), giving it roughly 19,7 additional feet of deck space compared to the EdgeWater 205CX 2010 at 2,0 feet (2010). At 28 lbs and 24 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 250 hp, the EdgeWater 210IS 2013 has a 25-hp advantage over the EdgeWater 205CX 2010's 225-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 2010 carries 75 gallons versus 55 gallons in the EdgeWater 210IS 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 205CX 2010 is rated for 9 passengers, while the EdgeWater 210IS 2013 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 2010 could be the deciding factor.
