The Key Largo 186 Bay 2013 vs Key Largo 206 2006 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 186 Bay 2013 measures 18,2 feet overall (2013), giving it roughly 16,2 additional feet of deck space compared to the Key Largo 206 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Key Largo 186 Bay 2013 tips the scales at 155 lbs — 131 lbs more than the Key Largo 206 2006 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.
The power gap is worth calling out. Rated to 200 hp, the Key Largo 206 2006 has a 85-hp advantage over the Key Largo 186 Bay 2013'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 Largo 206 2006 carries 85 gallons versus 22 gallons in the Key Largo 186 Bay 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 Largo 206 2006 is rated for 8 passengers, while the Key Largo 186 Bay 2013 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Key Largo 206 2006 could be the deciding factor.
Bottom line: Choose the Key Largo 206 2006 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Key Largo 186 Bay 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
