When two boats share the same hull type — in this case both the EdgeWater 188CC 2009 and the EdgeWater 210IS 2012 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 2012 measures 21,7 feet overall (2012), giving it roughly 3,7 additional feet of deck space compared to the EdgeWater 188CC 2009 at 18,0 feet (2009). Weight tells a clearer story for trailering families: the EdgeWater 188CC 2009 tips the scales at 205 lbs — 181 lbs more than the EdgeWater 210IS 2012 at 24 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 250 hp, the EdgeWater 210IS 2012 has a 100-hp advantage over the EdgeWater 188CC 2009's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 54 gal and 55 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The EdgeWater 188CC 2009 is rated for 7 passengers, while the EdgeWater 210IS 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the EdgeWater 188CC 2009 could be the deciding factor.
