Matching a modified vee Princecraft Sport 172 2011 against a pontoon Princecraft Vectra 21-4S 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Princecraft Vectra 21-4S 2011 measures 21,5 feet overall (2011), giving it roughly 4,1 additional feet of deck space compared to the Princecraft Sport 172 2011 at 17,4 feet (2011). Weight tells a clearer story for trailering families: the Princecraft Vectra 21-4S 2011 tips the scales at 1 748 lbs — 523 lbs less than the Princecraft Sport 172 2011 at 1 225 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 Vectra 21-4S 2011'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 2011 carries 35 gallons versus 18 gallons in the Princecraft Vectra 21-4S 2011. 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 Vectra 21-4S 2011 is rated for 8 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 Vectra 21-4S 2011 could be the deciding factor.
