Both the AB Inflatables 19 VST 2012 and the AB Inflatables 8 AL 2008 are rigid inflatable designs, the first built in fibreglass and the second in aluminium, 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?
Size is the most obvious dividing line here. The AB Inflatables 19 VST 2012 measures 19,0 feet overall (2012), giving it roughly 11,0 additional feet of deck space compared to the AB Inflatables 8 AL 2008 at 8,0 feet (2008). Weight tells a clearer story for trailering families: the AB Inflatables 19 VST 2012 tips the scales at 1 252 lbs - 1 179 lbs more than the AB Inflatables 8 AL 2008 at 73 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 115 hp, the AB Inflatables 19 VST 2012 has a 111-hp advantage over the AB Inflatables 8 AL 2008's 4-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 19 VST 2012 is rated for 15 passengers, while the AB Inflatables 8 AL 2008 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 19 VST 2012 could be the deciding factor.
Bottom line: Choose the AB Inflatables 19 VST 2012 if your priority is putting more people on the water - it handles 15 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The AB Inflatables 8 AL 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
