Triton Boats 173 Sport 2006 vs Triton Boats X18 2013 — Same Brand, Different Boat

The Triton Boats 173 Sport 2006 vs Triton Boats X18 2013 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 — Triton Boats 173 Sport 2006 at 17,0 ft versus Triton Boats X18 2013 at 18,7 ft. At 93 lbs and 118 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.

Both boats share a closely matched power ceiling — 80 hp for the Triton Boats 173 Sport 2006 and 90 hp for the Triton Boats X18 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 18 gal and 21 gal — so range won't be a tiebreaker here.

Both boats are rated for 4 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: The Triton Boats 173 Sport 2006 and Triton Boats X18 2013 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Triton Boats 173 Sport 2006 vs Triton Boats X18 2013 — Common Questions

Which is the larger boat — the Triton Boats 173 Sport 2006 or the Triton Boats X18 2013?
The Triton Boats X18 2013 is the longer of the two at 18,7 feet overall. The Triton Boats 173 Sport 2006 comes in at 17,0 feet, making it roughly 1,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Triton Boats 173 Sport 2006 or the Triton Boats X18 2013?
For trailering, the Triton Boats 173 Sport 2006 has the edge at 93 lbs dry weight versus 118 lbs for the Triton Boats X18 2013. 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 Triton Boats X18 2013 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Triton Boats 173 Sport 2006 tops out at 80 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 Triton Boats 173 Sport 2006 is Coast Guard rated for 4 passengers, while the Triton Boats X18 2013 is certified for 4. 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 Triton Boats X18 2013 measures 92" wide, compared to 75" for the Triton Boats 173 Sport 2006. 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 Triton Boats 173 Sport 2006 or the Triton Boats X18 2013?
The Triton Boats X18 2013 has the bigger tank at 21 gallons, versus 18 gallons on the Triton Boats 173 Sport 2006. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Triton Boats 173 Sport 2006 and Triton Boats X18 2013 from the same manufacturer?
Yes — both the Triton Boats 173 Sport 2006 and the Triton Boats X18 2013 are built by Triton Boats. 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.
