When two boats share the same hull type — in this case both the Zodiac ProJet 350 TC4 2011 and the Zodiac Yachtline Deluxe 530 DL 2010 are inflatable rigid designs with fiberglass 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 Yachtline Deluxe 530 DL 2010 measures 17,4 feet overall (2010), giving it roughly 5,9 additional feet of deck space compared to the Zodiac ProJet 350 TC4 2011 at 11,5 feet (2011). Weight tells a clearer story for trailering families: the Zodiac Yachtline Deluxe 530 DL 2010 tips the scales at 882 lbs — 221 lbs less than the Zodiac ProJet 350 TC4 2011 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 — 98 hp for the Zodiac ProJet 350 TC4 2011 and 115 hp for the Zodiac Yachtline Deluxe 530 DL 2010. 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. Fuel capacity breaks the other way: the Zodiac Yachtline Deluxe 530 DL 2010 carries 32 gallons versus 12 gallons in the Zodiac ProJet 350 TC4 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Zodiac Yachtline Deluxe 530 DL 2010 is rated for 9 passengers, while the Zodiac ProJet 350 TC4 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Yachtline Deluxe 530 DL 2010 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac ProJet 350 TC4 2011 comes in at 7 lbs per hp versus 8 lbs per hp for the Zodiac Yachtline Deluxe 530 DL 2010. 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 44 mph for the Zodiac Yachtline Deluxe 530 DL 2010 and 44 mph for the Zodiac ProJet 350 TC4 2011.
Bottom line: Choose the Zodiac Yachtline Deluxe 530 DL 2010 if your priority is putting more people on the water — it handles 9 passengers and at 17,4 ft it has the deck room to back that rating up comfortably. The Zodiac ProJet 350 TC4 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
