When two boats share the same hull type — in this case both the Key West 197 SK 2010 and the Key West 210 LS 2007 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?

The power gap is worth calling out. Rated to 200 hp, the Key West 210 LS 2007 has a 85-hp advantage over the Key West 197 SK 2010's 115-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 210 LS 2007 carries 49 gallons versus 19 gallons in the Key West 197 SK 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
