Sessa Marine Key Largo One 2013 vs Sessa Marine S 26 2012 — Which Deep Vee Fits Your Needs?

When two boats share the same hull type — in this case both the Sessa Marine Key Largo One 2013 and the Sessa Marine S 26 2012 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 Sessa Marine S 26 2012 measures 25,1 feet overall (2012), giving it roughly 6,3 additional feet of deck space compared to the Sessa Marine Key Largo One 2013 at 18,8 feet (2013). Weight tells a clearer story for trailering families: the Sessa Marine S 26 2012 tips the scales at 4 997 lbs — 3 233 lbs less than the Sessa Marine Key Largo One 2013 at 1 764 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 115 hp, the Sessa Marine Key Largo One 2013 has a 107-hp advantage over the Sessa Marine S 26 2012's 8-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 S 26 2012 carries 78 gallons versus 26 gallons in the Sessa Marine Key Largo One 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 Sessa Marine S 26 2012 is rated for 7 passengers, while the Sessa Marine Key Largo One 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sessa Marine S 26 2012 could be the deciding factor.

Bottom line: Choose the Sessa Marine S 26 2012 if your priority is putting more people on the water — it handles 7 passengers and at 25,1 ft it has the deck room to back that rating up comfortably. The Sessa Marine Key Largo One 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Sessa Marine Key Largo One 2013 vs Sessa Marine S 26 2012 — Common Questions

Which is the larger boat — the Sessa Marine Key Largo One 2013 or the Sessa Marine S 26 2012?
The Sessa Marine S 26 2012 is the longer of the two at 25,1 feet overall. The Sessa Marine Key Largo One 2013 comes in at 18,8 feet, making it roughly 6,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sessa Marine Key Largo One 2013 or the Sessa Marine S 26 2012?
For trailering, the Sessa Marine Key Largo One 2013 has the edge at 1 764 lbs dry weight versus 4 997 lbs for the Sessa Marine S 26 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Sessa Marine Key Largo One 2013 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Sessa Marine S 26 2012 tops out at 8 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sessa Marine Key Largo One 2013 is Coast Guard rated for 6 passengers, while the Sessa Marine S 26 2012 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sessa Marine S 26 2012 measures 98" wide, compared to 91" for the Sessa Marine Key Largo One 2013. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Sessa Marine Key Largo One 2013 or the Sessa Marine S 26 2012?
The Sessa Marine S 26 2012 has the bigger tank at 78 gallons, versus 26 gallons on the Sessa Marine Key Largo One 2013. That 51-gallon difference translates to roughly 154–258 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sessa Marine Key Largo One 2013 and Sessa Marine S 26 2012 from the same manufacturer?
Yes — both the Sessa Marine Key Largo One 2013 and the Sessa Marine S 26 2012 are built by Sessa Marine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
