The Key Largo 206 2006 vs Key Largo 2100 WI 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Key Largo 2100 WI 2013 measures 21,0 feet overall (2013), giving it roughly 19,0 additional feet of deck space compared to the Key Largo 206 2006 at 2,0 feet (2006). At 24 lbs and 29 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.
Both boats share a closely matched power ceiling — 200 hp for the Key Largo 206 2006 and 200 hp for the Key Largo 2100 WI 2013. 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. Both carry nearly identical fuel loads — 85 gal and 85 gal — so range won't be a tiebreaker here.
Both boats are rated for 8 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.
Bottom line: The Key Largo 2100 WI 2013 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Key Largo 206 2006 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
