Four Winns 245 Sundowner 2004 vs Four Winns 310 Horizon 2007 - Boat Spec Comparison

Q: Which is easier to trailer — the Four Winns 245 Sundowner 2004 or the Four Winns 310 Horizon 2007?

For trailering, the Four Winns 310 Horizon 2007 has the edge at 74 lbs dry weight versus 445 lbs for the Four Winns 245 Sundowner 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.

Q: How many people can each boat hold?

The Four Winns 245 Sundowner 2004 is Coast Guard rated for 8 passengers, while the Four Winns 310 Horizon 2007 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.

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

The Four Winns 310 Horizon 2007 measures 116" wide, compared to 102" for the Four Winns 245 Sundowner 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: Which boat has the larger fuel tank — the Four Winns 245 Sundowner 2004 or the Four Winns 310 Horizon 2007?

The Four Winns 245 Sundowner 2004 has the bigger tank at 65 gallons, versus 13 gallons on the Four Winns 310 Horizon 2007. That 52-gallon difference translates to roughly 156–260 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Four Winns 245 Sundowner 2004 and Four Winns 310 Horizon 2007 from the same manufacturer?

Yes — both the Four Winns 245 Sundowner 2004 and the Four Winns 310 Horizon 2007 are built by Four Winns. 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

Four Winns 245 Sundowner 2004 vs Four Winns 310 Horizon 2007 — Same Brand, Different Boat

The Four Winns 245 Sundowner 2004 vs Four Winns 310 Horizon 2007 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.

For family outings this is probably the sharpest distinction between the two. The Four Winns 310 Horizon 2007 is rated for 9 passengers, while the Four Winns 245 Sundowner 2004 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Four Winns 310 Horizon 2007 could be the deciding factor.

Bottom line: Choose the Four Winns 310 Horizon 2007 if your priority is putting more people on the water — it handles 9 passengers and at 31,0 ft it has the deck room to back that rating up comfortably. The Four Winns 245 Sundowner 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
