Ultracraft 1231 2011 vs Ultracraft Jon Boat 1031 2007 — Same Brand, Different Boat

The Ultracraft 1231 2011 vs Ultracraft Jon Boat 1031 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.

Size is the most obvious dividing line here. The Ultracraft 1231 2011 measures 11,8 feet overall (2011), giving it roughly 10,8 additional feet of deck space compared to the Ultracraft Jon Boat 1031 2007 at 1,0 feet (2007). At 8 lbs and 7 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 6 hp for the Ultracraft 1231 2011 and 4 hp for the Ultracraft Jon Boat 1031 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

Both boats are rated for 2 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Ultracraft 1231 2011 comes in at 1 lbs per hp versus 2 lbs per hp for the Ultracraft Jon Boat 1031 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: The Ultracraft 1231 2011 at 11,8 ft is the right call if deck space, comfort, and entertaining are top of your list. The Ultracraft Jon Boat 1031 2007 at 1,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Ultracraft 1231 2011 vs Ultracraft Jon Boat 1031 2007 — Common Questions

Which is the larger boat — the Ultracraft 1231 2011 or the Ultracraft Jon Boat 1031 2007?
The Ultracraft 1231 2011 is the longer of the two at 11,8 feet overall. The Ultracraft Jon Boat 1031 2007 comes in at 1,0 feet, making it roughly 10,8 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Ultracraft 1231 2011 or the Ultracraft Jon Boat 1031 2007?
For trailering, the Ultracraft Jon Boat 1031 2007 has the edge at 7 lbs dry weight versus 8 lbs for the Ultracraft 1231 2011. 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.
How many people can each boat hold?
The Ultracraft 1231 2011 is Coast Guard rated for 2 passengers, while the Ultracraft Jon Boat 1031 2007 is certified for 2. 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 better power-to-weight ratio?
The Ultracraft 1231 2011 has a better power-to-weight ratio at 1 lbs per hp compared to 2 lbs per hp for the Ultracraft Jon Boat 1031 2007. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Ultracraft 1231 2011 and Ultracraft Jon Boat 1031 2007 share an 46 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.
Are the Ultracraft 1231 2011 and Ultracraft Jon Boat 1031 2007 from the same manufacturer?
Yes — both the Ultracraft 1231 2011 and the Ultracraft Jon Boat 1031 2007 are built by Ultracraft. 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.
