The Key Largo 176 2007 vs Key Largo 2100 WA 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 WA 2013 measures 21,0 feet overall (2013), giving it roughly 4,0 additional feet of deck space compared to the Key Largo 176 2007 at 17,0 feet (2007). Weight tells a clearer story for trailering families: the Key Largo 176 2007 tips the scales at 1 375 lbs — 1 346 lbs more than the Key Largo 2100 WA 2013 at 29 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 2100 WA 2013 has a 110-hp advantage over the Key Largo 176 2007's 90-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 2100 WA 2013 carries 85 gallons versus 35 gallons in the Key Largo 176 2007. 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 2100 WA 2013 is rated for 8 passengers, while the Key Largo 176 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 Largo 2100 WA 2013 could be the deciding factor.
Bottom line: Choose the Key Largo 2100 WA 2013 if your priority is putting more people on the water — it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Key Largo 176 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
