Matching a flat Lowe L1648M 2010 against a modified vee Lowe ST190 2009 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 L1648M 2010 at 15,8 ft versus Lowe ST190 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Lowe L1648M 2010 tips the scales at 275 lbs — 169 lbs more than the Lowe ST190 2009 at 106 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 115 hp, the Lowe ST190 2009 has a 80-hp advantage over the Lowe L1648M 2010's 35-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Lowe ST190 2009 is rated for 5 passengers, while the Lowe L1648M 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe ST190 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe ST190 2009 comes in at 1 lbs per hp versus 8 lbs per hp for the Lowe L1648M 2010. 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.
