The Lowe ML200 2005 vs Lowe ST170 2009 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.

Size is the most obvious dividing line here. The Lowe ST170 2009 measures 17,0 feet overall (2009), giving it roughly 15,0 additional feet of deck space compared to the Lowe ML200 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Lowe ML200 2005 tips the scales at 1 644 lbs — 649 lbs more than the Lowe ST170 2009 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 ML200 2005 and 75 hp for the Lowe ST170 2009. 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 ML200 2005 carries 24 gallons versus 2 gallons in the Lowe ST170 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 ST170 2009 is rated for 4 passengers, while the Lowe ML200 2005 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe ST170 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe ST170 2009 comes in at 13 lbs per hp versus 18 lbs per hp for the Lowe ML200 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.
