Matching a inflatable non rigid Mercury 380 Heavy-Duty 2008 against a inflatable rigid Mercury 400 Amanzi Hypalon 2013 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Mercury 380 Heavy-Duty 2008 at 12,0 ft versus Mercury 400 Amanzi Hypalon 2013 at 13,0 ft. Weight tells a clearer story for trailering families: the Mercury 400 Amanzi Hypalon 2013 tips the scales at 775 lbs — 554 lbs less than the Mercury 380 Heavy-Duty 2008 at 221 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 50 hp, the Mercury 400 Amanzi Hypalon 2013 has a 25-hp advantage over the Mercury 380 Heavy-Duty 2008's 25-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 Mercury 380 Heavy-Duty 2008 is rated for 6 passengers, while the Mercury 400 Amanzi Hypalon 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury 380 Heavy-Duty 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 380 Heavy-Duty 2008 comes in at 9 lbs per hp versus 16 lbs per hp for the Mercury 400 Amanzi Hypalon 2013. 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.
