Both the Princecraft Vectra 21 2011 and the Princecraft Vectra 21-4S 2013 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 21 2011 at 21,5 ft versus Princecraft Vectra 21-4S 2013 at 21,5 ft. Weight tells a clearer story for trailering families: the Princecraft Vectra 21-4S 2013 tips the scales at 1 813 lbs - 174 lbs less than the Princecraft Vectra 21 2011 at 1 639 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 21-4S 2013 has a 25-hp advantage over the Princecraft Vectra 21 2011's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Princecraft Vectra 21 2011 carries 33 gallons versus 18 gallons in the Princecraft Vectra 21-4S 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 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.
