When two boats share the same hull type — in this case both the Lowe A1667WT 2011 and the Lowe ST175 2009 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 A1667WT 2011 at 16,0 ft versus Lowe ST175 2009 at 17,0 ft. Weight tells a clearer story for trailering families: the Lowe ST175 2009 tips the scales at 995 lbs — 951 lbs less than the Lowe A1667WT 2011 at 44 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 75 hp, the Lowe ST175 2009 has a 45-hp advantage over the Lowe A1667WT 2011's 30-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 A1667WT 2011 is rated for 5 passengers, while the Lowe ST175 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe A1667WT 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Lowe A1667WT 2011 comes in at 2 lbs per hp versus 13 lbs per hp for the Lowe ST175 2009. 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.
