Both the AB Inflatables 15 AL 2008 and the AB Inflatables 15 DLX 2012 are rigid inflatable designs, the first built in aluminium and the second 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 AL 2008 at 15,0 ft versus AB Inflatables 15 DLX 2012 at 15,0 ft. Weight tells a clearer story for trailering families: the AB Inflatables 15 DLX 2012 tips the scales at 739 lbs - 474 lbs less than the AB Inflatables 15 AL 2008 at 265 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 60 hp, the AB Inflatables 15 DLX 2012 has a 30-hp advantage over the AB Inflatables 15 AL 2008's 30-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

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 AL 2008 comes in at 9 lbs per hp versus 12 lbs per hp for the AB Inflatables 15 DLX 2012. 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.
