Princecraft SP 186 Platinum SE 2006 vs Princecraft Ungava 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Princecraft SP 186 Platinum SE 2006 or the Princecraft Ungava 2004?

For trailering, the Princecraft Ungava 2004 has the edge at 156 lbs dry weight versus 1 404 lbs for the Princecraft SP 186 Platinum SE 2006. 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.

Q: Which boat can handle a bigger outboard?

The Princecraft SP 186 Platinum SE 2006 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Princecraft Ungava 2004 tops out at 15 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.

Q: How many people can each boat hold?

The Princecraft SP 186 Platinum SE 2006 is Coast Guard rated for 8 passengers, while the Princecraft Ungava 2004 is certified for 4. 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.

Q: Which boat is wider, and does it affect trailering?

The Princecraft SP 186 Platinum SE 2006 measures 94" wide, compared to 6" for the Princecraft Ungava 2004. 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.

Q: Are the Princecraft SP 186 Platinum SE 2006 and Princecraft Ungava 2004 from the same manufacturer?

Yes — both the Princecraft SP 186 Platinum SE 2006 and the Princecraft Ungava 2004 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.

Detailed Evaluation & Buyer Recommendation

Princecraft SP 186 Platinum SE 2006 vs Princecraft Ungava 2004 — Same Brand, Different Boat

The Princecraft SP 186 Platinum SE 2006 vs Princecraft Ungava 2004 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.

The power gap is worth calling out. Rated to 175 hp, the Princecraft SP 186 Platinum SE 2006 has a 160-hp advantage over the Princecraft Ungava 2004's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Princecraft SP 186 Platinum SE 2006 is rated for 8 passengers, while the Princecraft Ungava 2004 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft SP 186 Platinum SE 2006 could be the deciding factor.

Bottom line: Choose the Princecraft SP 186 Platinum SE 2006 if your priority is putting more people on the water — it handles 8 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Princecraft Ungava 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
