When two boats share the same hull type — in this case both the EdgeWater 188CC 2009 and the EdgeWater 190IS 2011 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?

On paper these two are close siblings in the size department — EdgeWater 188CC 2009 at 18,0 ft versus EdgeWater 190IS 2011 at 18,7 ft. At 205 lbs and 215 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.

Both boats share a closely matched power ceiling — 150 hp for the EdgeWater 188CC 2009 and 150 hp for the EdgeWater 190IS 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the EdgeWater 188CC 2009 carries 54 gallons versus 4 gallons in the EdgeWater 190IS 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
