The Zodiac Zoom 240 2008 vs Zodiac Zoom 310 SR 2007 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Zodiac Zoom 240 2008 measures 7,0 feet overall (2008), giving it roughly 6,0 additional feet of deck space compared to the Zodiac Zoom 310 SR 2007 at 1,0 feet (2007). At 46 lbs and 93 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 4 hp for the Zodiac Zoom 240 2008 and 8 hp for the Zodiac Zoom 310 SR 2007. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The Zodiac Zoom 310 SR 2007 is rated for 4 passengers, while the Zodiac Zoom 240 2008 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 310 SR 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Zoom 240 2008 comes in at 12 lbs per hp versus 12 lbs per hp for the Zodiac Zoom 310 SR 2007. 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: Choose the Zodiac Zoom 310 SR 2007 if your priority is putting more people on the water — it handles 4 passengers and at 1,0 ft it has the deck room to back that rating up comfortably. The Zodiac Zoom 240 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
