Matching a inflatable rigid Mercury 350 Amanzi 2009 against a inflatable non rigid Mercury V-620 2008 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 2009 measures 11,0 feet overall (2009), giving it roughly 9,0 additional feet of deck space compared to the Mercury V-620 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Mercury V-620 2008 tips the scales at 1 071 lbs — 1 067 lbs less than the Mercury 350 Amanzi 2009 at 4 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 150 hp, the Mercury V-620 2008 has a 120-hp advantage over the Mercury 350 Amanzi 2009's 30-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 V-620 2008 is rated for 17 passengers, while the Mercury 350 Amanzi 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury V-620 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury 350 Amanzi 2009 comes in at 0 lbs per hp versus 7 lbs per hp for the Mercury V-620 2008. 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.
