Detailed Evaluation & Buyer Recommendation
Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 vs Zodiac Pro Open 550 2013 — Same Brand, Different Boat
The Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 vs Zodiac Pro Open 550 2013 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Both boats share a closely matched power ceiling — 115 hp for the Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 and 120 hp for the Zodiac Pro Open 550 2013. 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 Open 5.5 PVC 115hp T-Top On Order 2021 carries 26 gallons versus 2 gallons in the Zodiac Pro Open 550 2013. 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 Pro Open 550 2013 is rated for 11 passengers, while the Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Pro Open 550 2013 could be the deciding factor.
The Zodiac Pro Open 550 2013 has a documented top speed of 45 mph. Speed data wasn't available for the other model.
The Zodiac Pro Open 550 2013 is an inflatable design — lighter, easier to store, and quicker to launch from a beach or dock without a slipway. The Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 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 Pro Open 550 2013 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 Open 5.5 PVC 115hp T-Top On Order 2021 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
