When two boats share the same hull type — in this case both the AB Inflatables 13 VS 2012 and the AB Inflatables 28 VST 2008 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 2008 measures 28,0 feet overall (2008), giving it roughly 15,0 additional feet of deck space compared to the AB Inflatables 13 VS 2012 at 13,0 feet (2012). At 279 lbs and 286 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 300 hp, the AB Inflatables 28 VST 2008 has a 270-hp advantage over the AB Inflatables 13 VS 2012's 30-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 AB Inflatables 28 VST 2008 is rated for 25 passengers, while the AB Inflatables 13 VS 2012 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables 28 VST 2008 could be the deciding factor.
