The Princecraft 191V L4S O/B 2006 vs Princecraft SS 172 2009 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 191V L4S O/B 2006 at 19,0 ft versus Princecraft SS 172 2009 at 17,4 ft. Weight tells a clearer story for trailering families: the Princecraft SS 172 2009 tips the scales at 1 225 lbs — 1 029 lbs less than the Princecraft 191V L4S O/B 2006 at 196 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 Princecraft 191V L4S O/B 2006 has a 35-hp advantage over the Princecraft SS 172 2009'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 SS 172 2009 carries 35 gallons versus 5 gallons in the Princecraft 191V L4S O/B 2006. 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 Princecraft SS 172 2009 is rated for 6 passengers, while the Princecraft 191V L4S O/B 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft SS 172 2009 could be the deciding factor.
