Matching a deep vee Zodiac Medline Sundream 2012 against a inflatable rigid Zodiac Yachtline Deluxe 530 DL 2011 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.
On paper these two are close siblings in the size department — Zodiac Medline Sundream 2012 at 16,4 ft versus Zodiac Yachtline Deluxe 530 DL 2011 at 17,4 ft. At 875 lbs and 882 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.
The power gap is worth calling out. Rated to 115 hp, the Zodiac Yachtline Deluxe 530 DL 2011 has a 35-hp advantage over the Zodiac Medline Sundream 2012's 80-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Zodiac Yachtline Deluxe 530 DL 2011 carries 32 gallons versus 16 gallons in the Zodiac Medline Sundream 2012. 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 2011 is rated for 9 passengers, while the Zodiac Medline Sundream 2012 caps at 1. 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 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Yachtline Deluxe 530 DL 2011 comes in at 8 lbs per hp versus 11 lbs per hp for the Zodiac Medline Sundream 2012. 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 2011 and 42 mph for the Zodiac Medline Sundream 2012.
The Zodiac Medline Sundream 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Yachtline Deluxe 530 DL 2011 is a rigid hull, which typically offers a more confident ride in chop and easier maintenance over the long term.
Bottom line: Choose the Zodiac Yachtline Deluxe 530 DL 2011 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 Medline Sundream 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
