The Princecraft Pro 166 2007 vs Princecraft Sport 172 2010 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 — Princecraft Pro 166 2007 at 16,0 ft versus Princecraft Sport 172 2010 at 17,4 ft. Weight tells a clearer story for trailering families: the Princecraft Sport 172 2010 tips the scales at 1 225 lbs — 216 lbs less than the Princecraft Pro 166 2007 at 1 009 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 Princecraft Sport 172 2010 has a 25-hp advantage over the Princecraft Pro 166 2007's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Princecraft Sport 172 2010 carries 35 gallons versus 28 gallons in the Princecraft Pro 166 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft Sport 172 2010 comes in at 11 lbs per hp versus 11 lbs per hp for the Princecraft Pro 166 2007. 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.
