Matching a inflatable non rigid Zodiac Cadet Roll Up 240 2009 against a inflatable rigid Zodiac Zoom 400 SR 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.
The power gap is worth calling out. Rated to 30 hp, the Zodiac Zoom 400 SR 2008 has a 26-hp advantage over the Zodiac Cadet Roll Up 240 2009's 4-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 Zodiac Zoom 400 SR 2008 is rated for 7 passengers, while the Zodiac Cadet Roll Up 240 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Zoom 400 SR 2008 could be the deciding factor.
Bottom line: Choose the Zodiac Zoom 400 SR 2008 if your priority is putting more people on the water — it handles 7 passengers and at 13,0 ft it has the deck room to back that rating up comfortably. The Zodiac Cadet Roll Up 240 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
