Lowe ST190 2009 vs Lowe TR184 2005 — Same Brand, Different Boat

The Lowe ST190 2009 vs Lowe TR184 2005 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 — Lowe ST190 2009 at 18,0 ft versus Lowe TR184 2005 at 18,0 ft. Weight tells a clearer story for trailering families: the Lowe TR184 2005 tips the scales at 1 522 lbs — 1 416 lbs less than the Lowe ST190 2009 at 106 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 115 hp, the Lowe ST190 2009 has a 55-hp advantage over the Lowe TR184 2005's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Lowe TR184 2005 carries 24 gallons versus 2 gallons in the Lowe ST190 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Lowe TR184 2005 is rated for 9 passengers, while the Lowe ST190 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe TR184 2005 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe ST190 2009 comes in at 1 lbs per hp versus 25 lbs per hp for the Lowe TR184 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: Choose the Lowe TR184 2005 if your priority is putting more people on the water — it handles 9 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lowe ST190 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Lowe ST190 2009 vs Lowe TR184 2005 — Common Questions

Which is the larger boat — the Lowe ST190 2009 or the Lowe TR184 2005?
The Lowe TR184 2005 is the longer of the two at 18,0 feet overall. The Lowe ST190 2009 comes in at 18,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Lowe ST190 2009 or the Lowe TR184 2005?
For trailering, the Lowe ST190 2009 has the edge at 106 lbs dry weight versus 1 522 lbs for the Lowe TR184 2005. 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 Lowe ST190 2009 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Lowe TR184 2005 tops out at 60 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 Lowe ST190 2009 is Coast Guard rated for 5 passengers, while the Lowe TR184 2005 is certified for 9. 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 Lowe ST190 2009 has a better power-to-weight ratio at 1 lbs per hp compared to 25 lbs per hp for the Lowe TR184 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 Lowe TR184 2005 measures 96" wide, compared to 85" for the Lowe ST190 2009. 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 Lowe ST190 2009 or the Lowe TR184 2005?
The Lowe TR184 2005 has the bigger tank at 24 gallons, versus 2 gallons on the Lowe ST190 2009. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Lowe ST190 2009 and Lowe TR184 2005 from the same manufacturer?
Yes — both the Lowe ST190 2009 and the Lowe TR184 2005 are built by Lowe. 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.
