Matching a flat Ultracraft 1436 2011 against a modified vee Ultracraft 166T 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department — Ultracraft 1436 2011 at 14,0 ft versus Ultracraft 166T 2012 at 16,5 ft. Weight tells a clearer story for trailering families: the Ultracraft 1436 2011 tips the scales at 175 lbs — 106 lbs more than the Ultracraft 166T 2012 at 69 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 1436 2011 and 6 hp for the Ultracraft 166T 2012. 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 166T 2012 is rated for 5 passengers, while the Ultracraft 1436 2011 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Ultracraft 166T 2012 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Ultracraft 166T 2012 comes in at 12 lbs per hp versus 12 lbs per hp for the Ultracraft 1436 2011. 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 166T 2012 if your priority is putting more people on the water — it handles 5 passengers and at 16,5 ft it has the deck room to back that rating up comfortably. The Ultracraft 1436 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
