The Princecraft Sport 172 WS 2013 is a deep-V design and the Princecraft Vision 21 2010 is a pontoon design, so you're likely deciding between two noticeably 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 Vision 21 2010 measures 21,2 feet overall (2010), giving it roughly 3,8 additional feet of deck space compared to the Princecraft Sport 172 WS 2013 at 17,4 feet (2013). Weight tells a clearer story for trailering families: the Princecraft Vision 21 2010 tips the scales at 1 744 lbs - 489 lbs less than the Princecraft Sport 172 WS 2013 at 1 255 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 125 hp, the Princecraft Sport 172 WS 2013 has a 35-hp advantage over the Princecraft Vision 21 2010'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 Vision 21 2010 carries 33 gallons versus 26 gallons in the Princecraft Sport 172 WS 2013. 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 Vision 21 2010 is rated for 10 passengers, while the Princecraft Sport 172 WS 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Vision 21 2010 could be the deciding factor.
