Matching a deep vee Princecraft Platinum SE 186 2013 against a pontoon Princecraft Vectra 21-4S 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Princecraft Platinum SE 186 2013 at 18,5 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 — 268 lbs less than the Princecraft Platinum SE 186 2013 at 1 545 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 Platinum SE 186 2013 has a 60-hp advantage over the Princecraft Vectra 21-4S 2013's 115-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 21-4S 2013 carries 18 gallons versus 4 gallons in the Princecraft Platinum SE 186 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.
