Princecraft 20 ST 2004 vs Princecraft Pro 186 2009 — Same Brand, Different Boat

The Princecraft 20 ST 2004 vs Princecraft Pro 186 2009 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 Pro 186 2009 measures 18,5 feet overall (2009), giving it roughly 16,5 additional feet of deck space compared to the Princecraft 20 ST 2004 at 2,0 feet (2004). Weight tells a clearer story for trailering families: the Princecraft 20 ST 2004 tips the scales at 1 734 lbs — 1 585 lbs more 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 Princecraft Pro 186 2009 tops out at 175 hp. Engine specs for the Princecraft 20 ST 2004 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Princecraft 20 ST 2004 carries 34 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.

For family outings this is probably the sharpest distinction between the two. The Princecraft 20 ST 2004 is rated for 13 passengers, while the Princecraft Pro 186 2009 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princecraft 20 ST 2004 could be the deciding factor.

Bottom line: Choose the Princecraft 20 ST 2004 if your priority is putting more people on the water — it handles 13 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Princecraft Pro 186 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

Princecraft 20 ST 2004 vs Princecraft Pro 186 2009 — Common Questions

Which is the larger boat — the Princecraft 20 ST 2004 or the Princecraft Pro 186 2009?
The Princecraft Pro 186 2009 is the longer of the two at 18,5 feet overall. The Princecraft 20 ST 2004 comes in at 2,0 feet, making it roughly 16,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Princecraft 20 ST 2004 or the Princecraft Pro 186 2009?
For trailering, the Princecraft Pro 186 2009 has the edge at 149 lbs dry weight versus 1 734 lbs for the Princecraft 20 ST 2004. 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.
What is the maximum horsepower rating for these boats?

How many people can each boat hold?
The Princecraft 20 ST 2004 is Coast Guard rated for 13 passengers, while the Princecraft Pro 186 2009 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 20 ST 2004 measures 96" 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.

The Princecraft 20 ST 2004 has the bigger tank at 34 gallons, versus 4 gallons on the Princecraft Pro 186 2009. That 30-gallon difference translates to roughly 90–150 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Princecraft 20 ST 2004 and Princecraft Pro 186 2009 from the same manufacturer?
Yes — both the Princecraft 20 ST 2004 and the Princecraft Pro 186 2009 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.
