The AB Inflatables F 28 2011 vs AB-Inflatables Nautilus 15 DLX 2019 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 AB Inflatables F 28 2011 measures 28,0 feet overall (2011), giving it roughly 13,0 additional feet of deck space compared to the AB-Inflatables Nautilus 15 DLX 2019 at 15,0 feet (2019). Weight tells a clearer story for trailering families: the AB Inflatables F 28 2011 tips the scales at 3 146 lbs — 2 380 lbs more than the AB-Inflatables Nautilus 15 DLX 2019 at 766 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.

The power gap is worth calling out. Rated to 250 hp, the AB Inflatables F 28 2011 has a 190-hp advantage over the AB-Inflatables Nautilus 15 DLX 2019's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the AB Inflatables F 28 2011 carries 132 gallons versus 27 gallons in the AB-Inflatables Nautilus 15 DLX 2019. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The AB Inflatables F 28 2011 is rated for 25 passengers, while the AB-Inflatables Nautilus 15 DLX 2019 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables F 28 2011 could be the deciding factor.
