When two boats share the same hull type — in this case both the Key West 152 CC 2011 and the Key West 1720 DC 2009 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?

On paper these two are close siblings in the size department — Key West 152 CC 2011 at 15,2 ft versus Key West 1720 DC 2009 at 17,0 ft. At 95 lbs and 12 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.

The power gap is worth calling out. Rated to 120 hp, the Key West 1720 DC 2009 has a 40-hp advantage over the Key West 152 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 1720 DC 2009 carries 31 gallons versus 2 gallons in the Key West 152 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 1720 DC 2009 is rated for 5 passengers, while the Key West 152 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 1720 DC 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Key West 1720 DC 2009 comes in at 0 lbs per hp versus 1 lbs per hp for the Key West 152 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.
