Sun Tracker Party Barge 20 Regency Edition 2008 vs Sun Tracker Party Deck 21 I/O 2004 - Boat Spec Comparison

Q: Which is easier to trailer — the Sun Tracker Party Barge 20 Regency Edition 2008 or the Sun Tracker Party Deck 21 I/O 2004?

For trailering, the Sun Tracker Party Deck 21 I/O 2004 has the edge at 206 lbs dry weight versus 2 283 lbs for the Sun Tracker Party Barge 20 Regency Edition 2008. 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: What is the maximum horsepower rating for these boats?

The Sun Tracker Party Barge 20 Regency Edition 2008 has a documented max rating of 125 hp. Engine specifications for the Sun Tracker Party Deck 21 I/O 2004 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.

Q: How many people can each boat hold?

The Sun Tracker Party Barge 20 Regency Edition 2008 is Coast Guard rated for 12 passengers, while the Sun Tracker Party Deck 21 I/O 2004 is certified for 10. 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: Do these boats require an oversize trailer permit to tow on US highways?

Both the Sun Tracker Party Barge 20 Regency Edition 2008 and Sun Tracker Party Deck 21 I/O 2004 share an 8 ft. 6 in. (deck width) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.

Q: Which boat has the larger fuel tank — the Sun Tracker Party Barge 20 Regency Edition 2008 or the Sun Tracker Party Deck 21 I/O 2004?

The Sun Tracker Party Barge 20 Regency Edition 2008 has the bigger tank at 45 gallons, versus 41 gallons on the Sun Tracker Party Deck 21 I/O 2004. That 4-gallon difference translates to roughly 12–20 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Sun Tracker Party Barge 20 Regency Edition 2008 and Sun Tracker Party Deck 21 I/O 2004 from the same manufacturer?

Yes — both the Sun Tracker Party Barge 20 Regency Edition 2008 and the Sun Tracker Party Deck 21 I/O 2004 are built by Sun Tracker. 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

Sun Tracker Party Barge 20 Regency Edition 2008 vs Sun Tracker Party Deck 21 I/O 2004 — Same Brand, Different Boat

The Sun Tracker Party Barge 20 Regency Edition 2008 vs Sun Tracker Party Deck 21 I/O 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 Sun Tracker Party Barge 20 Regency Edition 2008 carries a rated maximum of 125 hp. Engine data for the Sun Tracker Party Deck 21 I/O 2004 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Sun Tracker Party Barge 20 Regency Edition 2008 carries 45 gallons versus 41 gallons in the Sun Tracker Party Deck 21 I/O 2004. 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 Sun Tracker Party Barge 20 Regency Edition 2008 is rated for 12 passengers, while the Sun Tracker Party Deck 21 I/O 2004 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sun Tracker Party Barge 20 Regency Edition 2008 could be the deciding factor.

Bottom line: Choose the Sun Tracker Party Barge 20 Regency Edition 2008 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Sun Tracker Party Deck 21 I/O 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
