When two boats share the same hull type — in this case both the Lowe SD190 2012 and the Lowe ST195 2011 are modified vee designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Lowe SD190 2012 at 18,8 ft versus Lowe ST195 2011 at 18,7 ft. Weight tells a clearer story for trailering families: the Lowe SD190 2012 tips the scales at 1 985 lbs — 1 879 lbs more than the Lowe ST195 2011 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 150 hp, the Lowe SD190 2012 has a 35-hp advantage over the Lowe ST195 2011's 115-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 SD190 2012 carries 27 gallons versus 2 gallons in the Lowe ST195 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 SD190 2012 is rated for 10 passengers, while the Lowe ST195 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe SD190 2012 could be the deciding factor.
