Both the Princecraft Vectra 19 2011 and the Princecraft Vectra 20 SF 2010 are pontoon designs, both built in aluminium, so 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 19 2011 at 19,6 ft versus Princecraft Vectra 20 SF 2010 at 20,3 ft. Weight tells a clearer story for trailering families: the Princecraft Vectra 20 SF 2010 tips the scales at 1 650 lbs - 148 lbs less than the Princecraft Vectra 19 2011 at 1 502 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 - 75 hp for the Princecraft Vectra 19 2011 and 90 hp for the Princecraft Vectra 20 SF 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.

For family outings this is probably the sharpest distinction between the two. The Princecraft Vectra 20 SF 2010 is rated for 8 passengers, while the Princecraft Vectra 19 2011 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Vectra 20 SF 2010 could be the deciding factor.

One place where both boats are genuinely identical is tube construction: both run 2 aluminum tubes at 23" diameter. That shared spec means stability and buoyancy characteristics are closely matched - the ride difference you'll feel between them comes primarily from deck length, weight distribution, and motor choice.
