The Princecraft 20 LPF 2006 vs Princecraft Sport 172 2011 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.

Size is the most obvious dividing line here. The Princecraft Sport 172 2011 measures 17,4 feet overall (2011), giving it roughly 15,4 additional feet of deck space compared to the Princecraft 20 LPF 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Princecraft Sport 172 2011 tips the scales at 1 225 lbs — 1 030 lbs less than the Princecraft 20 LPF 2006 at 195 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 2011 has a 25-hp advantage over the Princecraft 20 LPF 2006's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 33 gal and 35 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Princecraft 20 LPF 2006 is rated for 11 passengers, while the Princecraft Sport 172 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft 20 LPF 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Princecraft 20 LPF 2006 comes in at 2 lbs per hp versus 11 lbs per hp for the Princecraft Sport 172 2011. 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.
