When two boats share the same hull type — in this case both the Key West 1720 DC 2007 and the Key West 230 BR 2013 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 250 hp, the Key West 230 BR 2013 has a 130-hp advantage over the Key West 1720 DC 2007'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 2007 carries 31 gallons versus 8 gallons in the Key West 230 BR 2013. 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 230 BR 2013 is rated for 7 passengers, while the Key West 1720 DC 2007 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 230 BR 2013 could be the deciding factor.
