The Lowe FS185 2005 vs Lowe RV170 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 FS185 2005 at 18,0 ft versus Lowe RV170 2011 at 17,3 ft. Weight tells a clearer story for trailering families: the Lowe RV170 2011 tips the scales at 739 lbs — 727 lbs less than the Lowe FS185 2005 at 12 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 FS185 2005 has a 90-hp advantage over the Lowe RV170 2011's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe FS185 2005 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe FS185 2005 comes in at 0 lbs per hp versus 12 lbs per hp for the Lowe RV170 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.
