Matching a deep vee Lowe FS185 2009 against a modified vee Lowe ST170 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Lowe FS185 2009 at 18,0 ft versus Lowe ST170 2011 at 17,4 ft. Weight tells a clearer story for trailering families: the Lowe ST170 2011 tips the scales at 995 lbs — 860 lbs less than the Lowe FS185 2009 at 135 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 2009 has a 75-hp advantage over the Lowe ST170 2011'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 FS185 2009 carries 38 gallons versus 2 gallons in the Lowe ST170 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 FS185 2009 is rated for 7 passengers, while the Lowe ST170 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 FS185 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe FS185 2009 comes in at 1 lbs per hp versus 13 lbs per hp for the Lowe ST170 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.
