When two boats share the same hull type — in this case both the Sessa Marine Key Largo 20 2012 and the Sessa Marine Key Largo 24 2012 are modified 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 Sessa Marine Key Largo 24 2012 measures 22,5 feet overall (2012), giving it roughly 20,5 additional feet of deck space compared to the Sessa Marine Key Largo 20 2012 at 2,0 feet (2012). Weight tells a clearer story for trailering families: the Sessa Marine Key Largo 24 2012 tips the scales at 3 086 lbs — 551 lbs less than the Sessa Marine Key Largo 20 2012 at 2 535 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 250 hp, the Sessa Marine Key Largo 24 2012 has a 100-hp advantage over the Sessa Marine Key Largo 20 2012's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sessa Marine Key Largo 24 2012 carries 71 gallons versus 53 gallons in the Sessa Marine Key Largo 20 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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.
