Both the Key West 1520 CC 2011 and the Key West 176 DC 2007 are modified-V designs, both built in fibreglass, so 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 - Key West 1520 CC 2011 at 15,2 ft versus Key West 176 DC 2007 at 17,0 ft. Weight tells a clearer story for trailering families: the Key West 176 DC 2007 tips the scales at 1 375 lbs - 425 lbs less than the Key West 1520 CC 2011 at 950 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 140 hp, the Key West 176 DC 2007 has a 60-hp advantage over the Key West 1520 CC 2011's 80-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 176 DC 2007 carries 40 gallons versus 20 gallons in the Key West 1520 CC 2011. 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 176 DC 2007 is rated for 5 passengers, while the Key West 1520 CC 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Key West 176 DC 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Key West 176 DC 2007 comes in at 10 lbs per hp versus 12 lbs per hp for the Key West 1520 CC 2011. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
