The Princecraft Pro 186 2007 vs Princecraft Vectra 21-2S 2013 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 2013 measures 21,5 feet overall (2013), giving it roughly 3,5 additional feet of deck space compared to the Princecraft Pro 186 2007 at 18,0 feet (2007). Weight tells a clearer story for trailering families: the Princecraft Vectra 21-2S 2013 tips the scales at 1 724 lbs — 1 575 lbs less than the Princecraft Pro 186 2007 at 149 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 175 hp, the Princecraft Pro 186 2007 has a 60-hp advantage over the Princecraft Vectra 21-2S 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 4 gal and 3 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 2013 is rated for 10 passengers, while the Princecraft Pro 186 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Vectra 21-2S 2013 could be the deciding factor.
