Princecraft Sport 172 2011 vs Princecraft Vectra 21 2012 — Same Brand, Different Boat

Matching a modified vee Princecraft Sport 172 2011 against a pontoon Princecraft Vectra 21 2012 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 2012 measures 21,5 feet overall (2012), 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 2012 tips the scales at 1 704 lbs — 479 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 2012'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 Vectra 21 2012 is rated for 10 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 2012 could be the deciding factor.

Bottom line: Choose the Princecraft Vectra 21 2012 if your priority is putting more people on the water — it handles 10 passengers and at 21,5 ft it has the deck room to back that rating up comfortably. The Princecraft Sport 172 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Princecraft Sport 172 2011 vs Princecraft Vectra 21 2012 — Common Questions

Which is the larger boat — the Princecraft Sport 172 2011 or the Princecraft Vectra 21 2012?
The Princecraft Vectra 21 2012 is the longer of the two at 21,5 feet overall. The Princecraft Sport 172 2011 comes in at 17,4 feet, making it roughly 4,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Princecraft Sport 172 2011 or the Princecraft Vectra 21 2012?
For trailering, the Princecraft Sport 172 2011 has the edge at 1 225 lbs dry weight versus 1 704 lbs for the Princecraft Vectra 21 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Princecraft Sport 172 2011 is rated to a maximum of 115 hp, giving it the larger power ceiling. The Princecraft Vectra 21 2012 tops out at 90 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Princecraft Sport 172 2011 is Coast Guard rated for 6 passengers, while the Princecraft Vectra 21 2012 is certified for 10. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Princecraft Vectra 21 2012 measures 101" wide, compared to 92" for the Princecraft Sport 172 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Princecraft Sport 172 2011 and Princecraft Vectra 21 2012?
Both boats carry similar fuel loads — 35 gallons and 33 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Princecraft Sport 172 2011 and Princecraft Vectra 21 2012 from the same manufacturer?
Yes — both the Princecraft Sport 172 2011 and the Princecraft Vectra 21 2012 are built by Princecraft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
