When two boats share the same hull type — in this case both the Princecraft Vectra 21 XT 2013 and the Princecraft Vectra 21-2S 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?

On paper these two are close siblings in the size department — Princecraft Vectra 21 XT 2013 at 21,5 ft versus Princecraft Vectra 21-2S 2012 at 21,5 ft. Weight tells a clearer story for trailering families: the Princecraft Vectra 21-2S 2012 tips the scales at 1 724 lbs — 1 551 lbs less than the Princecraft Vectra 21 XT 2013 at 173 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 Vectra 21 XT 2013 has a 25-hp advantage over the Princecraft Vectra 21-2S 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 — 32 gal and 31 gal — so range won't be a tiebreaker here.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
