Both the AB Inflatables 15 DLX 2008 and the AB Inflatables 15 VST 2012 are rigid inflatable designs, both built in fibreglass, so 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?

On paper these two are close siblings in the size department - AB Inflatables 15 DLX 2008 at 15,0 ft versus AB Inflatables 15 VST 2012 at 15,0 ft. At 682 lbs and 605 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.

Both boats share a closely matched power ceiling - 50 hp for the AB Inflatables 15 DLX 2008 and 60 hp for the AB Inflatables 15 VST 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. Both carry nearly identical fuel loads - 26 gal and 25 gal - so range won't be a tiebreaker here.

Both boats are rated for 9 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The AB Inflatables 15 VST 2012 comes in at 10 lbs per hp versus 14 lbs per hp for the AB Inflatables 15 DLX 2008. 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.
