The Lowe ST170 2009 vs Lowe TR220SD 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.

Size is the most obvious dividing line here. The Lowe TR220SD 2005 measures 22,0 feet overall (2005), giving it roughly 5,0 additional feet of deck space compared to the Lowe ST170 2009 at 17,0 feet (2009). Weight tells a clearer story for trailering families: the Lowe TR220SD 2005 tips the scales at 2 913 lbs — 1 918 lbs less 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.

The power gap is worth calling out. Rated to 135 hp, the Lowe TR220SD 2005 has a 60-hp advantage over the Lowe ST170 2009's 75-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 TR220SD 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 TR220SD 2005 is rated for 12 passengers, while the Lowe ST170 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe TR220SD 2005 could be the deciding factor.
