Ultracraft Jon Boat 1031 2006 vs Ultracraft Jon Boat 1236 2008 — Same Brand, Different Boat

The Ultracraft Jon Boat 1031 2006 vs Ultracraft Jon Boat 1236 2008 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 Jon Boat 1236 2008 measures 12,0 feet overall (2008), giving it roughly 11,0 additional feet of deck space compared to the Ultracraft Jon Boat 1031 2006 at 1,0 feet (2006). At 7 lbs and 14 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 — 4 hp for the Ultracraft Jon Boat 1031 2006 and 10 hp for the Ultracraft Jon Boat 1236 2008. 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.

For family outings this is probably the sharpest distinction between the two. The Ultracraft Jon Boat 1236 2008 is rated for 3 passengers, while the Ultracraft Jon Boat 1031 2006 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ultracraft Jon Boat 1236 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Ultracraft Jon Boat 1236 2008 comes in at 1 lbs per hp versus 2 lbs per hp for the Ultracraft Jon Boat 1031 2006. 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: Choose the Ultracraft Jon Boat 1236 2008 if your priority is putting more people on the water — it handles 3 passengers and at 12,0 ft it has the deck room to back that rating up comfortably. The Ultracraft Jon Boat 1031 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.

How many people can each boat hold?
