Sessa Marine Fly 54 2013 vs Sessa Marine Key Largo One 2012 — Same Brand, Different Boat

Matching a deep vee Sessa Marine Fly 54 2013 against a modified vee Sessa Marine Key Largo One 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Sessa Marine Fly 54 2013 measures 53,6 feet overall (2013), giving it roughly 34,8 additional feet of deck space compared to the Sessa Marine Key Largo One 2012 at 18,8 feet (2012). Weight tells a clearer story for trailering families: the Sessa Marine Key Largo One 2012 tips the scales at 1 742 lbs — 1 257 lbs less than the Sessa Marine Fly 54 2013 at 485 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 1 400 hp, the Sessa Marine Fly 54 2013 has a 1 210-hp advantage over the Sessa Marine Key Largo One 2012's 190-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 Fly 54 2013 carries 264 gallons versus 26 gallons in the Sessa Marine Key Largo One 2012. 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 Fly 54 2013 is rated for 14 passengers, while the Sessa Marine Key Largo One 2012 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 Fly 54 2013 could be the deciding factor.

Bottom line: Choose the Sessa Marine Fly 54 2013 if your priority is putting more people on the water — it handles 14 passengers and at 53,6 ft it has the deck room to back that rating up comfortably. The Sessa Marine Key Largo One 2012 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 Fly 54 2013 vs Sessa Marine Key Largo One 2012 — Common Questions

Which is the larger boat — the Sessa Marine Fly 54 2013 or the Sessa Marine Key Largo One 2012?
The Sessa Marine Fly 54 2013 is the longer of the two at 53,6 feet overall. The Sessa Marine Key Largo One 2012 comes in at 18,8 feet, making it roughly 34,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sessa Marine Fly 54 2013 or the Sessa Marine Key Largo One 2012?
For trailering, the Sessa Marine Fly 54 2013 has the edge at 485 lbs dry weight versus 1 742 lbs for the Sessa Marine Key Largo One 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 Fly 54 2013 is rated to a maximum of 1 400 hp, giving it the larger power ceiling. The Sessa Marine Key Largo One 2012 tops out at 190 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 Fly 54 2013 is Coast Guard rated for 14 passengers, while the Sessa Marine Key Largo One 2012 is certified for 6. 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 Fly 54 2013 measures 184" wide, compared to 89" for the Sessa Marine Key Largo One 2012. 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 Fly 54 2013 or the Sessa Marine Key Largo One 2012?
The Sessa Marine Fly 54 2013 has the bigger tank at 264 gallons, versus 26 gallons on the Sessa Marine Key Largo One 2012. That 237-gallon difference translates to roughly 712–1188 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sessa Marine Fly 54 2013 and Sessa Marine Key Largo One 2012 from the same manufacturer?
Yes — both the Sessa Marine Fly 54 2013 and the Sessa Marine Key Largo One 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.
