The Ultracraft 189FS 2012 vs Ultracraft Stealth 178W 2006 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.
On paper these two are close siblings in the size department — Ultracraft 189FS 2012 at 18,8 ft versus Ultracraft Stealth 178W 2006 at 17,0 ft. At 178 lbs and 112 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.
The power gap is worth calling out. Rated to 115 hp, the Ultracraft Stealth 178W 2006 has a 100-hp advantage over the Ultracraft 189FS 2012's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Ultracraft 189FS 2012 is rated for 8 passengers, while the Ultracraft Stealth 178W 2006 caps at 6. 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 Stealth 178W 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
