Zodiac Medline vs. Zodiac Open: Which Zodiac RIB Line Is Right for You?
When shopping for a premium rigid inflatable boat (RIB), Zodiac offers two standout lines that appeal to very different types of boaters: the Zodiac Medline series and the Zodiac Open series. While both share Zodiac’s renowned RIB heritage, performance-oriented hulls, and family-friendly versatility, each line is designed with a different primary mission in mind.
The Medline lineup focuses on comfort, relaxation, entertaining, and all-day cruising. The Open lineup leans more toward utility, watersports, offshore capability, fishing, and active boating.
If you are trying to decide between the two, understanding how each line is designed — and how you plan to use your boat — will make the decision much easier.
Understanding the Zodiac Medline Series
The Zodiac Medline line is built around the concept of “private beach on the water.” These boats prioritize social spaces, large sunpads, comfortable seating layouts, and easy movement throughout the deck.
The Medline series is ideal for:
- Family day boating
- Sandbar trips
- Entertaining guests
- Coastal cruising
- Swimming and lounging
- Yacht tender use
- Relaxed watersports
Compared to the Open line, Medline models generally feature:
- Larger sun lounges
- More upscale upholstery and comfort amenities
- Convertible seating areas
- Greater emphasis on relaxation
- Softer, more luxurious deck layouts
The Medline series still delivers the performance benefits of a Zodiac RIB — including stability, lightweight construction, and excellent rough-water handling — but comfort and social usability are clearly the priority.

Understanding the Zodiac Open Series
While the Medline line focuses on comfort and leisure, the Zodiac Open line is designed around versatility and activity.

Medline vs. Open: Key Differences
1. Comfort vs. Utility
The biggest distinction between the two lines is how the deck space is used.
Medline boats prioritize:
- Sunpads
- Lounging areas
- Convertible seating
- Relaxation
- Entertaining
Open boats prioritize:
- Deck space
- Movement around the boat
- Watersports functionality
- Fishing utility
- Offshore practicality
If your boating days revolve around anchoring, relaxing, swimming, and entertaining, the Medline is likely the better fit.
If your boating days involve activity, fishing, diving, watersports, or offshore exploration, the Open series may make more sense.
2. Seating Layouts
The Medline line features more elaborate seating arrangements and larger social zones.
The Open line typically uses simpler bench seating and more open deck areas to maximize flexibility.
3. Watersports and Fishing
Both lines can handle watersports, but the Open series generally performs better for:
- Fishing setups
- Diving access
- Tow sports
- Active movement around the boat
The Medline line can still tow tubes and skiers comfortably, but its layouts are more optimized for relaxing once the activity ends.
4. Offshore Capability
Both series benefit from Zodiac’s RIB hull designs, which are known for stability, soft rides, and efficiency.
However, the Open series is typically chosen more often by owners prioritizing offshore performance and utility-driven boating.
5. Luxury Feel
The Medline lineup generally feels more upscale and refined, especially in the larger models.
Premium upholstery, expansive sunbeds, integrated social spaces, and convertible layouts give the Medline series a more luxury-dayboat-oriented personality.
