Matching a inflatable non rigid Mercury 240 Roll-Up 2008 against a inflatable rigid Mercury V-520/570 Series 2009 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 V-520/570 Series 2009 measures 17,0 feet overall (2009), giving it roughly 10,0 additional feet of deck space compared to the Mercury 240 Roll-Up 2008 at 7,0 feet (2008). Weight tells a clearer story for trailering families: the Mercury V-520/570 Series 2009 tips the scales at 578 lbs — 516 lbs less than the Mercury 240 Roll-Up 2008 at 62 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 100 hp, the Mercury V-520/570 Series 2009 has a 95-hp advantage over the Mercury 240 Roll-Up 2008's 5-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-520/570 Series 2009 is rated for 9 passengers, while the Mercury 240 Roll-Up 2008 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury V-520/570 Series 2009 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Mercury V-520/570 Series 2009 comes in at 6 lbs per hp versus 12 lbs per hp for the Mercury 240 Roll-Up 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.
