Detailed Evaluation & Buyer Recommendation
Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 vs Zodiac Pro Open 850 2011 — Same Brand, Different Boat
The Zodiac Open 5.5 PVC 115hp T-Top On Order 2021 vs Zodiac Pro Open 850 2011 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.
The power gap is worth calling out. Rated to 350 hp, the Zodiac Pro Open 850 2011 has a 235-hp advantage over the Zodiac Open 5.5 PVC 115hp T-Top On Order 2021's 115-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 Pro Open 850 2011 carries 106 gallons versus 26 gallons in the Zodiac Open 5.5 PVC 115hp T-Top On Order 2021. 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 850 2011 is rated for 8 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 850 2011 could be the deciding factor.
Bottom line: Choose the Zodiac Pro Open 850 2011 if your priority is putting more people on the water — it handles 8 passengers and at 27,9 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.
