When two boats share the same hull type — in this case both the Princecraft Pro 185 GL 2009 and the Princecraft Sport 172 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 — Princecraft Pro 185 GL 2009 at 18,5 ft versus Princecraft Sport 172 2011 at 17,4 ft. Weight tells a clearer story for trailering families: the Princecraft Sport 172 2011 tips the scales at 1 225 lbs — 1 080 lbs less than the Princecraft Pro 185 GL 2009 at 145 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 175 hp, the Princecraft Pro 185 GL 2009 has a 60-hp advantage over the Princecraft Sport 172 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 Princecraft Sport 172 2011 carries 35 gallons versus 4 gallons in the Princecraft Pro 185 GL 2009. 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.
