The Ultracraft 189FS 2012 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 189FS 2012 measures 18,8 feet overall (2012), giving it roughly 17,8 additional feet of deck space compared to the Ultracraft Jon Boat 1031 2007 at 1,0 feet (2007). Weight tells a clearer story for trailering families: the Ultracraft 189FS 2012 tips the scales at 178 lbs — 171 lbs more than the Ultracraft Jon Boat 1031 2007 at 7 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.
Both boats share a closely matched power ceiling — 15 hp for the Ultracraft 189FS 2012 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.
For family outings this is probably the sharpest distinction between the two. The Ultracraft 189FS 2012 is rated for 8 passengers, while the Ultracraft Jon Boat 1031 2007 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ultracraft 189FS 2012 could be the deciding factor.
Bottom line: Choose the Ultracraft 189FS 2012 if your priority is putting more people on the water — it handles 8 passengers and at 18,8 ft it has the deck room to back that rating up comfortably. The Ultracraft Jon Boat 1031 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
