Matching a deep vee Zodiac Medline Sundream 2012 against a inflatable rigid Zodiac Yachtline Deluxe 420 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 420 DL 2011 at 13,8 ft. Weight tells a clearer story for trailering families: the Zodiac Medline Sundream 2012 tips the scales at 875 lbs — 273 lbs more than the Zodiac Yachtline Deluxe 420 DL 2011 at 602 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 — 80 hp for the Zodiac Medline Sundream 2012 and 60 hp for the Zodiac Yachtline Deluxe 420 DL 2011. 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. Both carry nearly identical fuel loads — 16 gal and 15 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Zodiac Yachtline Deluxe 420 DL 2011 is rated for 6 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 420 DL 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Zodiac Yachtline Deluxe 420 DL 2011 comes in at 10 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 42 mph for the Zodiac Medline Sundream 2012 and 37 mph for the Zodiac Yachtline Deluxe 420 DL 2011.
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 420 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 420 DL 2011 if your priority is putting more people on the water — it handles 6 passengers and at 13,8 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.
