When two boats share the same hull type — in this case both the AB Inflatables 12 DLX 2010 and the AB Inflatables 28 VST 2013 are inflatable rigid designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The AB Inflatables 28 VST 2013 measures 28,0 feet overall (2013), giving it roughly 15,8 additional feet of deck space compared to the AB Inflatables 12 DLX 2010 at 12,3 feet (2010). Weight tells a clearer story for trailering families: the AB Inflatables 12 DLX 2010 tips the scales at 506 lbs — 220 lbs more than the AB Inflatables 28 VST 2013 at 286 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 400 hp, the AB Inflatables 28 VST 2013 has a 370-hp advantage over the AB Inflatables 12 DLX 2010's 30-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 28 VST 2013 carries 132 gallons versus 11 gallons in the AB Inflatables 12 DLX 2010. 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 28 VST 2013 is rated for 25 passengers, while the AB Inflatables 12 DLX 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables 28 VST 2013 could be the deciding factor.
