The Lowe FM185S 2005 vs Lowe ST160 2011 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 FM185S 2005 at 18,0 ft versus Lowe ST160 2011 at 16,0 ft. Weight tells a clearer story for trailering families: the Lowe ST160 2011 tips the scales at 865 lbs — 854 lbs less than the Lowe FM185S 2005 at 11 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 150 hp, the Lowe FM185S 2005 has a 100-hp advantage over the Lowe ST160 2011's 50-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 FM185S 2005 carries 38 gallons versus 13 gallons in the Lowe ST160 2011. 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 FM185S 2005 is rated for 7 passengers, while the Lowe ST160 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe FM185S 2005 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe FM185S 2005 comes in at 0 lbs per hp versus 17 lbs per hp for the Lowe ST160 2011. 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.
