When two boats share the same hull type — in this case both the Key West 1720 DC 2008 and the Key West 268 CC 2010 are modified 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 Key West 268 CC 2010 measures 26,7 feet overall (2010), giving it roughly 9,7 additional feet of deck space compared to the Key West 1720 DC 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Key West 268 CC 2010 tips the scales at 451 lbs — 439 lbs less than the Key West 1720 DC 2008 at 12 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 500 hp, the Key West 268 CC 2010 has a 380-hp advantage over the Key West 1720 DC 2008's 120-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Key West 1720 DC 2008 carries 31 gallons versus 18 gallons in the Key West 268 CC 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 Key West 268 CC 2010 is rated for 8 passengers, while the Key West 1720 DC 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Key West 268 CC 2010 could be the deciding factor.
Bottom line: Choose the Key West 268 CC 2010 if your priority is putting more people on the water — it handles 8 passengers and at 26,7 ft it has the deck room to back that rating up comfortably. The Key West 1720 DC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
