Triton Boats 170 Magnum 2005 vs Triton Boats TS-18 2007 — Same Brand, Different Boat

The Triton Boats 170 Magnum 2005 vs Triton Boats TS-18 2007 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 170 Magnum 2005 at 17,0 ft versus Triton Boats TS-18 2007 at 18,0 ft. At 103 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 — 115 hp for the Triton Boats 170 Magnum 2005 and 115 hp for the Triton Boats TS-18 2007. 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. Fuel capacity breaks the other way: the Triton Boats TS-18 2007 carries 22 gallons versus 18 gallons in the Triton Boats 170 Magnum 2005. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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 TS-18 2007 comes in at 1 lbs per hp versus 1 lbs per hp for the Triton Boats 170 Magnum 2005. 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: The Triton Boats 170 Magnum 2005 and Triton Boats TS-18 2007 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 170 Magnum 2005 vs Triton Boats TS-18 2007 — Common Questions

Which is the larger boat — the Triton Boats 170 Magnum 2005 or the Triton Boats TS-18 2007?
The Triton Boats TS-18 2007 is the longer of the two at 18,0 feet overall. The Triton Boats 170 Magnum 2005 comes in at 17,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Triton Boats 170 Magnum 2005 or the Triton Boats TS-18 2007?
For trailering, the Triton Boats 170 Magnum 2005 has the edge at 103 lbs dry weight versus 106 lbs for the Triton Boats TS-18 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.
How many people can each boat hold?
The Triton Boats 170 Magnum 2005 is Coast Guard rated for 4 passengers, while the Triton Boats TS-18 2007 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 TS-18 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 1 lbs per hp for the Triton Boats 170 Magnum 2005. 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-18 2007 measures 85" wide, compared to 78" for the Triton Boats 170 Magnum 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.
Which boat has the larger fuel tank — the Triton Boats 170 Magnum 2005 or the Triton Boats TS-18 2007?
The Triton Boats TS-18 2007 has the bigger tank at 22 gallons, versus 18 gallons on the Triton Boats 170 Magnum 2005. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Triton Boats 170 Magnum 2005 and Triton Boats TS-18 2007 from the same manufacturer?
Yes — both the Triton Boats 170 Magnum 2005 and the Triton Boats TS-18 2007 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.
