Detailed Evaluation & Buyer Recommendation
Zodiac 550 2009 vs Zodiac Medline IV 2012 — Same Brand, Different Boat
Matching a inflatable rigid Zodiac 550 2009 against a deep vee Zodiac Medline IV 2012 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.
The power gap is worth calling out. Rated to 350 hp, the Zodiac Medline IV 2012 has a 230-hp advantage over the Zodiac 550 2009's 120-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Zodiac 550 2009 is rated for 11 passengers, while the Zodiac Medline IV 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac 550 2009 could be the deciding factor.
The Zodiac Medline IV 2012 has a documented top speed of 57 mph. Speed data wasn't available for the other model.
The Zodiac Medline IV 2012 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac 550 2009 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 550 2009 if your priority is putting more people on the water — it handles 11 passengers and at 18,1 ft it has the deck room to back that rating up comfortably. The Zodiac Medline IV 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
