When two boats share the same hull type — in this case both the EdgeWater 245CC 2008 and the EdgeWater 318CC 2010 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 318CC 2010 measures 32,0 feet overall (2010), giving it roughly 8,0 additional feet of deck space compared to the EdgeWater 245CC 2008 at 24,0 feet (2008). At 34 lbs and 65 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 700 hp, the EdgeWater 318CC 2010 has a 350-hp advantage over the EdgeWater 245CC 2008's 350-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 245CC 2008 carries 15 gallons versus 3 gallons in the EdgeWater 318CC 2010. 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 2010 is rated for 12 passengers, while the EdgeWater 245CC 2008 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 318CC 2010 could be the deciding factor.
