Advantage 28 Party Cat XL 2007 vs Advantage 34 Offshore 2009 - Boat Spec Comparison

Q: Which is the larger boat — the Advantage 28 Party Cat XL 2007 or the Advantage 34 Offshore 2009?

The Advantage 34 Offshore 2009 is the longer of the two at 33,0 feet overall. The Advantage 28 Party Cat XL 2007 comes in at 28,0 feet, making it roughly 5,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer — the Advantage 28 Party Cat XL 2007 or the Advantage 34 Offshore 2009?

For trailering, the Advantage 28 Party Cat XL 2007 has the edge at 435 lbs dry weight versus 734 lbs for the Advantage 34 Offshore 2009. 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: How many people can each boat hold?

The Advantage 28 Party Cat XL 2007 is Coast Guard rated for 18 passengers, while the Advantage 34 Offshore 2009 is certified for 12. 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 Advantage 28 Party Cat XL 2007 and Advantage 34 Offshore 2009 share an 102 in 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 Advantage 28 Party Cat XL 2007 or the Advantage 34 Offshore 2009?

The Advantage 34 Offshore 2009 has the bigger tank at 195 gallons, versus 1 gallons on the Advantage 28 Party Cat XL 2007. That 194-gallon difference translates to roughly 582–970 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Advantage 28 Party Cat XL 2007 and Advantage 34 Offshore 2009 from the same manufacturer?

Yes — both the Advantage 28 Party Cat XL 2007 and the Advantage 34 Offshore 2009 are built by Advantage. 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

Advantage 28 Party Cat XL 2007 vs Advantage 34 Offshore 2009 — Same Brand, Different Boat

The Advantage 28 Party Cat XL 2007 vs Advantage 34 Offshore 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 Advantage 34 Offshore 2009 measures 33,0 feet overall (2009), giving it roughly 5,0 additional feet of deck space compared to the Advantage 28 Party Cat XL 2007 at 28,0 feet (2007). Weight tells a clearer story for trailering families: the Advantage 34 Offshore 2009 tips the scales at 734 lbs — 299 lbs less than the Advantage 28 Party Cat XL 2007 at 435 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.

For family outings this is probably the sharpest distinction between the two. The Advantage 28 Party Cat XL 2007 is rated for 18 passengers, while the Advantage 34 Offshore 2009 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Advantage 28 Party Cat XL 2007 could be the deciding factor.

Bottom line: Choose the Advantage 28 Party Cat XL 2007 if your priority is putting more people on the water — it handles 18 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The Advantage 34 Offshore 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
