Lowe Boats Legacy 2021 vs Lowe ST170 2010 — Same Brand, Different Boat

The Lowe Boats Legacy 2021 vs Lowe ST170 2010 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 Boats Legacy 2021 at 18,0 ft versus Lowe ST170 2010 at 17,4 ft. Weight tells a clearer story for trailering families: the Lowe Boats Legacy 2021 tips the scales at 1 129 lbs — 134 lbs more than the Lowe ST170 2010 at 995 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.

Both boats share a closely matched power ceiling — 90 hp for the Lowe Boats Legacy 2021 and 75 hp for the Lowe ST170 2010. 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 Lowe Boats Legacy 2021 carries 19 gallons versus 2 gallons in the Lowe ST170 2010. 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 Boats Legacy 2021 is rated for 5 passengers, while the Lowe ST170 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe Boats Legacy 2021 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe Boats Legacy 2021 comes in at 13 lbs per hp versus 13 lbs per hp for the Lowe ST170 2010. 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.

The Lowe Boats Legacy 2021 is trailerable — a genuine lifestyle advantage at this size. The Lowe ST170 2010 isn't listed as trailerable, which may mean a permanent berth or mooring is required.

Bottom line: Choose the Lowe Boats Legacy 2021 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lowe ST170 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Lowe Boats Legacy 2021 vs Lowe ST170 2010 — Common Questions

Which is the larger boat — the Lowe Boats Legacy 2021 or the Lowe ST170 2010?
The Lowe Boats Legacy 2021 is the longer of the two at 18,0 feet overall. The Lowe ST170 2010 comes in at 17,4 feet, making it roughly 0,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Lowe Boats Legacy 2021 or the Lowe ST170 2010?
For trailering, the Lowe ST170 2010 has the edge at 995 lbs dry weight versus 1 129 lbs for the Lowe Boats Legacy 2021. 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 Boats Legacy 2021 is rated to a maximum of 90 hp, giving it the larger power ceiling. The Lowe ST170 2010 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 Lowe Boats Legacy 2021 is Coast Guard rated for 5 passengers, while the Lowe ST170 2010 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 Lowe Boats Legacy 2021 has a better power-to-weight ratio at 13 lbs per hp compared to 13 lbs per hp for the Lowe ST170 2010. 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 Boats Legacy 2021 measures 102" wide, compared to 85" for the Lowe ST170 2010. 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 Boats Legacy 2021 or the Lowe ST170 2010?
The Lowe Boats Legacy 2021 has the bigger tank at 19 gallons, versus 2 gallons on the Lowe ST170 2010. That 17-gallon difference translates to roughly 51–85 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Lowe Boats Legacy 2021 and Lowe ST170 2010 from the same manufacturer?
Yes — both the Lowe Boats Legacy 2021 and the Lowe ST170 2010 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.
