Triton Boats 173 Sport 2005 vs Triton Boats TS-17 2011 — Same Brand, Different Boat

The Triton Boats 173 Sport 2005 vs Triton Boats TS-17 2011 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 2005 at 17,0 ft versus Triton Boats TS-17 2011 at 17,2 ft. At 93 lbs and 99 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.

The power gap is worth calling out. Rated to 80 hp, the Triton Boats 173 Sport 2005 has a 30-hp advantage over the Triton Boats TS-17 2011's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 18 gal and 19 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Triton Boats 173 Sport 2005 comes in at 1 lbs per hp versus 2 lbs per hp for the Triton Boats TS-17 2011. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Performance buyers should lean toward the Triton Boats 173 Sport 2005 and its 80-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Triton Boats TS-17 2011 with its 50-hp rating is the more economical daily driver.

Triton Boats 173 Sport 2005 vs Triton Boats TS-17 2011 — Common Questions

Which is the larger boat — the Triton Boats 173 Sport 2005 or the Triton Boats TS-17 2011?
The Triton Boats TS-17 2011 is the longer of the two at 17,2 feet overall. The Triton Boats 173 Sport 2005 comes in at 17,0 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 Triton Boats 173 Sport 2005 or the Triton Boats TS-17 2011?
For trailering, the Triton Boats 173 Sport 2005 has the edge at 93 lbs dry weight versus 99 lbs for the Triton Boats TS-17 2011. 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 173 Sport 2005 is rated to a maximum of 80 hp, giving it the larger power ceiling. The Triton Boats TS-17 2011 tops out at 50 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 2005 is Coast Guard rated for 4 passengers, while the Triton Boats TS-17 2011 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 has the better power-to-weight ratio?
The Triton Boats 173 Sport 2005 has a better power-to-weight ratio at 1 lbs per hp compared to 2 lbs per hp for the Triton Boats TS-17 2011. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Triton Boats TS-17 2011 measures 85" wide, compared to 75" for the Triton Boats 173 Sport 2005. 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.
How do the fuel tanks compare on the Triton Boats 173 Sport 2005 and Triton Boats TS-17 2011?
Both boats carry similar fuel loads — 18 gallons and 19 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Triton Boats 173 Sport 2005 and Triton Boats TS-17 2011 from the same manufacturer?
Yes — both the Triton Boats 173 Sport 2005 and the Triton Boats TS-17 2011 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.
