Matching a inflatable non rigid Mercury 310 Dynamic 2008 against a inflatable rigid Mercury 350 Amanzi Hypalon 2012 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.

Size is the most obvious dividing line here. The Mercury 350 Amanzi Hypalon 2012 measures 11,5 feet overall (2012), giving it roughly 10,5 additional feet of deck space compared to the Mercury 310 Dynamic 2008 at 1,0 feet (2008). Weight tells a clearer story for trailering families: the Mercury 350 Amanzi Hypalon 2012 tips the scales at 675 lbs — 563 lbs less than the Mercury 310 Dynamic 2008 at 112 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 40 hp, the Mercury 350 Amanzi Hypalon 2012 has a 30-hp advantage over the Mercury 310 Dynamic 2008's 10-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 4 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 Mercury 310 Dynamic 2008 comes in at 11 lbs per hp versus 17 lbs per hp for the Mercury 350 Amanzi Hypalon 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.
