When two boats share the same hull type — in this case both the Princecraft Cadet 2007 and the Princecraft Voyageur 21 2012 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Princecraft Voyageur 21 2012 measures 21,6 feet overall (2012), giving it roughly 5,6 additional feet of deck space compared to the Princecraft Cadet 2007 at 16,0 feet (2007). Weight tells a clearer story for trailering families: the Princecraft Voyageur 21 2012 tips the scales at 1 356 lbs — 768 lbs less than the Princecraft Cadet 2007 at 588 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 60 hp, the Princecraft Voyageur 21 2012 has a 35-hp advantage over the Princecraft Cadet 2007's 25-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Princecraft Voyageur 21 2012 is rated for 10 passengers, while the Princecraft Cadet 2007 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Voyageur 21 2012 could be the deciding factor.
Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
Bottom line: Choose the Princecraft Voyageur 21 2012 if your priority is putting more people on the water — it handles 10 passengers and at 21,6 ft it has the deck room to back that rating up comfortably. The Princecraft Cadet 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
