When two boats share the same hull type — in this case both the Zodiac Medline IIC 2008 and the Zodiac ProJet 350 2008 are inflatable rigid designs with rigid inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Zodiac Medline IIC 2008 measures 17,0 feet overall (2008), giving it roughly 6,0 additional feet of deck space compared to the Zodiac ProJet 350 2008 at 11,0 feet (2008). Weight tells a clearer story for trailering families: the Zodiac Medline IIC 2008 tips the scales at 881 lbs — 220 lbs more than the Zodiac ProJet 350 2008 at 661 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.
Both boats share a closely matched power ceiling — 115 hp for the Zodiac Medline IIC 2008 and 98 hp for the Zodiac ProJet 350 2008. 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 Medline IIC 2008 is rated for 9 passengers, while the Zodiac ProJet 350 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Medline IIC 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac ProJet 350 2008 comes in at 7 lbs per hp versus 8 lbs per hp for the Zodiac Medline IIC 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.
Top speed is rated at 45 mph for the Zodiac ProJet 350 2008 and 44 mph for the Zodiac Medline IIC 2008.
Bottom line: Choose the Zodiac Medline IIC 2008 if your priority is putting more people on the water — it handles 9 passengers and at 17,0 ft it has the deck room to back that rating up comfortably. The Zodiac ProJet 350 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
