Princecraft SP 178 SC SE 2006 vs Princecraft Versailles 21 2011 — Same Brand, Different Boat

The Princecraft SP 178 SC SE 2006 vs Princecraft Versailles 21 2011 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 Versailles 21 2011 measures 21,8 feet overall (2011), giving it roughly 4,8 additional feet of deck space compared to the Princecraft SP 178 SC SE 2006 at 17,0 feet (2006). At 117 lbs and 206 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 150 hp, the Princecraft SP 178 SC SE 2006 has a 60-hp advantage over the Princecraft Versailles 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 SP 178 SC SE 2006 carries 35 gallons versus 31 gallons in the Princecraft Versailles 21 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Princecraft Versailles 21 2011 is rated for 9 passengers, while the Princecraft SP 178 SC SE 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft Versailles 21 2011 could be the deciding factor.

Bottom line: Choose the Princecraft Versailles 21 2011 if your priority is putting more people on the water — it handles 9 passengers and at 21,8 ft it has the deck room to back that rating up comfortably. The Princecraft SP 178 SC SE 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Princecraft SP 178 SC SE 2006 vs Princecraft Versailles 21 2011 — Common Questions

Which is the larger boat — the Princecraft SP 178 SC SE 2006 or the Princecraft Versailles 21 2011?
The Princecraft Versailles 21 2011 is the longer of the two at 21,8 feet overall. The Princecraft SP 178 SC SE 2006 comes in at 17,0 feet, making it roughly 4,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Princecraft SP 178 SC SE 2006 or the Princecraft Versailles 21 2011?
For trailering, the Princecraft SP 178 SC SE 2006 has the edge at 117 lbs dry weight versus 206 lbs for the Princecraft Versailles 21 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 SP 178 SC SE 2006 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Princecraft Versailles 21 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 SP 178 SC SE 2006 is Coast Guard rated for 6 passengers, while the Princecraft Versailles 21 2011 is certified for 9. 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 Versailles 21 2011 measures 102" wide, compared to 92" for the Princecraft SP 178 SC SE 2006. 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 SP 178 SC SE 2006 or the Princecraft Versailles 21 2011?
The Princecraft SP 178 SC SE 2006 has the bigger tank at 35 gallons, versus 31 gallons on the Princecraft Versailles 21 2011. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Princecraft SP 178 SC SE 2006 and Princecraft Versailles 21 2011 from the same manufacturer?
Yes — both the Princecraft SP 178 SC SE 2006 and the Princecraft Versailles 21 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.
