Matching a inflatable non rigid Mercury 270 Air Deck Hypalon 2011 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.
On paper these two are close siblings in the size department — Mercury 270 Air Deck Hypalon 2011 at 8,8 ft versus Mercury 350 Amanzi Hypalon 2012 at 11,5 ft. Weight tells a clearer story for trailering families: the Mercury 350 Amanzi Hypalon 2012 tips the scales at 675 lbs — 583 lbs less than the Mercury 270 Air Deck Hypalon 2011 at 92 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 270 Air Deck Hypalon 2011'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 270 Air Deck Hypalon 2011 comes in at 9 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.
Bottom line: The Mercury 350 Amanzi Hypalon 2012 at 11,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Mercury 270 Air Deck Hypalon 2011 at 8,8 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
