Uniesse 55 2003 vs Uniesse Exuma S5 2023 — Same Brand, Different Boat

The Uniesse 55 2003 vs Uniesse Exuma S5 2023 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.

On paper these two are close siblings in the size department — Uniesse 55 2003 at 54,5 ft versus Uniesse Exuma S5 2023 at 54,7 ft. Weight tells a clearer story for trailering families: the Uniesse 55 2003 tips the scales at 61 289 lbs — 27 289 lbs more than the Uniesse Exuma S5 2023 at 34 000 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 800 hp, the Uniesse 55 2003 has a 200-hp advantage over the Uniesse Exuma S5 2023's 600-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Uniesse 55 2003 carries 819 gallons versus 7 gallons in the Uniesse Exuma S5 2023. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 16 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.

Bottom line: Performance buyers should lean toward the Uniesse 55 2003 and its 800-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Uniesse Exuma S5 2023 with its 600-hp rating is the more economical daily driver.

Uniesse 55 2003 vs Uniesse Exuma S5 2023 — Common Questions

Which is the larger boat — the Uniesse 55 2003 or the Uniesse Exuma S5 2023?
The Uniesse Exuma S5 2023 is the longer of the two at 54,7 feet overall. The Uniesse 55 2003 comes in at 54,5 feet, making it roughly 0,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Uniesse 55 2003 or the Uniesse Exuma S5 2023?
For trailering, the Uniesse Exuma S5 2023 has the edge at 34 000 lbs dry weight versus 61 289 lbs for the Uniesse 55 2003. 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 Uniesse 55 2003 is rated to a maximum of 800 hp, giving it the larger power ceiling. The Uniesse Exuma S5 2023 tops out at 600 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 Uniesse 55 2003 is Coast Guard rated for 16 passengers, while the Uniesse Exuma S5 2023 is certified for 16. 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 Uniesse 55 2003 measures 193" wide, compared to 182" for the Uniesse Exuma S5 2023. 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 Uniesse 55 2003 or the Uniesse Exuma S5 2023?
The Uniesse 55 2003 has the bigger tank at 819 gallons, versus 7 gallons on the Uniesse Exuma S5 2023. That 811-gallon difference translates to roughly 2435–4059 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Uniesse 55 2003 and Uniesse Exuma S5 2023 from the same manufacturer?
Yes — both the Uniesse 55 2003 and the Uniesse Exuma S5 2023 are built by Uniesse. 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.
