Princecraft Pro 186 2009 vs Princecraft Vectra 21-4S 2011 — Same Brand, Different Boat

Matching a modified vee Princecraft Pro 186 2009 against a pontoon Princecraft Vectra 21-4S 2011 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 Pro 186 2009 at 18,5 ft versus Princecraft Vectra 21-4S 2011 at 21,5 ft. Weight tells a clearer story for trailering families: the Princecraft Vectra 21-4S 2011 tips the scales at 1 748 lbs — 1 599 lbs less than the Princecraft Pro 186 2009 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 2009 has a 85-hp advantage over the Princecraft Vectra 21-4S 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 21-4S 2011 carries 18 gallons versus 4 gallons in the Princecraft Pro 186 2009. 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.

Bottom line: The Princecraft Vectra 21-4S 2011 at 21,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Princecraft Pro 186 2009 at 18,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Princecraft Pro 186 2009 vs Princecraft Vectra 21-4S 2011 — Common Questions

Which is the larger boat — the Princecraft Pro 186 2009 or the Princecraft Vectra 21-4S 2011?
The Princecraft Vectra 21-4S 2011 is the longer of the two at 21,5 feet overall. The Princecraft Pro 186 2009 comes in at 18,5 feet, making it roughly 3,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Princecraft Pro 186 2009 or the Princecraft Vectra 21-4S 2011?
For trailering, the Princecraft Pro 186 2009 has the edge at 149 lbs dry weight versus 1 748 lbs for the Princecraft Vectra 21-4S 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Princecraft Pro 186 2009 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Princecraft Vectra 21-4S 2011 tops out at 90 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Princecraft Pro 186 2009 is Coast Guard rated for 8 passengers, while the Princecraft Vectra 21-4S 2011 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Princecraft Vectra 21-4S 2011 measures 101" wide, compared to 95" for the Princecraft Pro 186 2009. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Princecraft Pro 186 2009 or the Princecraft Vectra 21-4S 2011?
The Princecraft Vectra 21-4S 2011 has the bigger tank at 18 gallons, versus 4 gallons on the Princecraft Pro 186 2009. That 14-gallon difference translates to roughly 42–70 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Princecraft Pro 186 2009 and Princecraft Vectra 21-4S 2011 from the same manufacturer?
Yes — both the Princecraft Pro 186 2009 and the Princecraft Vectra 21-4S 2011 are built by Princecraft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
