Jupiter 31 Forward Seating 2007 vs Jupiter Marine 38 2022 — Same Brand, Different Boat

The Jupiter 31 Forward Seating 2007 vs Jupiter Marine 38 2022 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 600 hp, the Jupiter 31 Forward Seating 2007 has a 200-hp advantage over the Jupiter Marine 38 2022's 400-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Jupiter Marine 38 2022 carries 475 gallons versus 26 gallons in the Jupiter 31 Forward Seating 2007. 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 Jupiter Marine 38 2022 is rated for 11 passengers, while the Jupiter 31 Forward Seating 2007 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jupiter Marine 38 2022 could be the deciding factor.

Bottom line: Choose the Jupiter Marine 38 2022 if your priority is putting more people on the water — it handles 11 passengers and at 38,0 ft it has the deck room to back that rating up comfortably. The Jupiter 31 Forward Seating 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Jupiter 31 Forward Seating 2007 vs Jupiter Marine 38 2022 — Common Questions

Which is the larger boat — the Jupiter 31 Forward Seating 2007 or the Jupiter Marine 38 2022?
The Jupiter Marine 38 2022 is the longer of the two at 38,0 feet overall. The Jupiter 31 Forward Seating 2007 comes in at 33,0 feet, making it roughly 5,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Jupiter 31 Forward Seating 2007 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Jupiter Marine 38 2022 tops out at 400 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.
How many people can each boat hold?
The Jupiter 31 Forward Seating 2007 is Coast Guard rated for 10 passengers, while the Jupiter Marine 38 2022 is certified for 11. 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 has the larger fuel tank — the Jupiter 31 Forward Seating 2007 or the Jupiter Marine 38 2022?
The Jupiter Marine 38 2022 has the bigger tank at 475 gallons, versus 26 gallons on the Jupiter 31 Forward Seating 2007. That 449-gallon difference translates to roughly 1347–2245 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Jupiter 31 Forward Seating 2007 and Jupiter Marine 38 2022 from the same manufacturer?
Yes — both the Jupiter 31 Forward Seating 2007 and the Jupiter Marine 38 2022 are built by Jupiter. 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.
