When two boats share the same hull type — in this case both the Key Largo 1800 CC 2013 and the Key Largo 236WI 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 236WI 2009 measures 23,0 feet overall (2009), giving it roughly 5,2 additional feet of deck space compared to the Key Largo 1800 CC 2013 at 17,8 feet (2013). At 22 lbs and 28 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.
The power gap is worth calling out. Rated to 250 hp, the Key Largo 236WI 2009 has a 135-hp advantage over the Key Largo 1800 CC 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 1800 CC 2013 carries 35 gallons versus 11 gallons in the Key Largo 236WI 2009. 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 236WI 2009 is rated for 9 passengers, while the Key Largo 1800 CC 2013 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 236WI 2009 could be the deciding factor.
Bottom line: Choose the Key Largo 236WI 2009 if your priority is putting more people on the water — it handles 9 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Key Largo 1800 CC 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
