Triton Boats SP 175 2007 vs Triton Boats TS-18 2011 — Same Brand, Different Boat

The Triton Boats SP 175 2007 vs Triton Boats TS-18 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 SP 175 2007 at 17,0 ft versus Triton Boats TS-18 2011 at 18,2 ft. At 112 lbs and 106 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 — 90 hp for the Triton Boats SP 175 2007 and 75 hp for the Triton Boats TS-18 2011. 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 — 22 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.

Bottom line: The Triton Boats SP 175 2007 and Triton Boats TS-18 2011 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 SP 175 2007 vs Triton Boats TS-18 2011 — Common Questions

Which is the larger boat — the Triton Boats SP 175 2007 or the Triton Boats TS-18 2011?
The Triton Boats TS-18 2011 is the longer of the two at 18,2 feet overall. The Triton Boats SP 175 2007 comes in at 17,0 feet, making it roughly 1,2 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Triton Boats SP 175 2007 or the Triton Boats TS-18 2011?
For trailering, the Triton Boats TS-18 2011 has the edge at 106 lbs dry weight versus 112 lbs for the Triton Boats SP 175 2007. 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 SP 175 2007 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Triton Boats TS-18 2011 tops out at 75 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 SP 175 2007 is Coast Guard rated for 4 passengers, while the Triton Boats TS-18 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Triton Boats SP 175 2007 and Triton Boats TS-18 2011 share an 85 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Triton Boats SP 175 2007 or the Triton Boats TS-18 2011?
The Triton Boats SP 175 2007 has the bigger tank at 22 gallons, versus 19 gallons on the Triton Boats TS-18 2011. 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 SP 175 2007 and Triton Boats TS-18 2011 from the same manufacturer?
Yes — both the Triton Boats SP 175 2007 and the Triton Boats TS-18 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.
