The Princecraft SS 172 2009 is a modified-V design and the Princecraft Vantage 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 Vantage 21 2010 measures 21,8 feet overall (2010), giving it roughly 4,3 additional feet of deck space compared to the Princecraft SS 172 2009 at 17,4 feet (2009). Weight tells a clearer story for trailering families: the Princecraft Vantage 21 2010 tips the scales at 1 801 lbs - 576 lbs less than the Princecraft SS 172 2009 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 SS 172 2009 has a 25-hp advantage over the Princecraft Vantage 21 2010'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 - 35 gal and 33 gal - so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Princecraft Vantage 21 2010 is rated for 10 passengers, while the Princecraft SS 172 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Vantage 21 2010 could be the deciding factor.
