When two boats share the same hull type — in this case both the Key Largo 186 2011 and the Key Largo 2000 LE 2009 are deep 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 Largo 186 2011 measures 18,0 feet overall (2011), giving it roughly 16,0 additional feet of deck space compared to the Key Largo 2000 LE 2009 at 2,0 feet (2009). Weight tells a clearer story for trailering families: the Key Largo 186 2011 tips the scales at 155 lbs — 131 lbs more than the Key Largo 2000 LE 2009 at 24 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.

Both boats share a closely matched power ceiling — 140 hp for the Key Largo 186 2011 and 150 hp for the Key Largo 2000 LE 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Key Largo 2000 LE 2009 carries 65 gallons versus 35 gallons in the Key Largo 186 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Key Largo 2000 LE 2009 comes in at 0 lbs per hp versus 1 lbs per hp for the Key Largo 186 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.
