The Princecraft Pro 164 SS 2006 vs Princecraft Vectra 21-2S 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Princecraft Vectra 21-2S 2012 measures 21,5 feet overall (2012), giving it roughly 5,5 additional feet of deck space compared to the Princecraft Pro 164 SS 2006 at 16,0 feet (2006). Weight tells a clearer story for trailering families: the Princecraft Vectra 21-2S 2012 tips the scales at 1 724 lbs — 739 lbs less than the Princecraft Pro 164 SS 2006 at 985 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.

Both boats share a closely matched power ceiling — 90 hp for the Princecraft Pro 164 SS 2006 and 90 hp for the Princecraft Vectra 21-2S 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 28 gal and 31 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Princecraft Vectra 21-2S 2012 is rated for 10 passengers, while the Princecraft Pro 164 SS 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Vectra 21-2S 2012 could be the deciding factor.
