When two boats share the same hull type — in this case both the EdgeWater 190IS 2012 and the EdgeWater 335EX 2010 are deep vee designs with composite 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?

The power gap is worth calling out. Rated to 700 hp, the EdgeWater 335EX 2010 has a 550-hp advantage over the EdgeWater 190IS 2012'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 190IS 2012 carries 45 gallons versus 3 gallons in the EdgeWater 335EX 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 335EX 2010 is rated for 12 passengers, while the EdgeWater 190IS 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 335EX 2010 could be the deciding factor.
