When two boats share the same hull type — in this case both the Princecraft Vectra 21-2S 2010 and the Princecraft Versailles 21 2010 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?

On paper these two are close siblings in the size department — Princecraft Vectra 21-2S 2010 at 21,5 ft versus Princecraft Versailles 21 2010 at 21,8 ft. Weight tells a clearer story for trailering families: the Princecraft Vectra 21-2S 2010 tips the scales at 1 639 lbs — 1 433 lbs more than the Princecraft Versailles 21 2010 at 206 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 Vectra 21-2S 2010 and 90 hp for the Princecraft Versailles 21 2010. 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 — 33 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 Versailles 21 2010 is rated for 9 passengers, while the Princecraft Vectra 21-2S 2010 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Versailles 21 2010 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.
