Zodiac 350 TC4 2009 vs Zodiac Pro Open 550 2008 — Which Inflatable Rigid Fits Your Needs?

When two boats share the same hull type — in this case both the Zodiac 350 TC4 2009 and the Zodiac Pro Open 550 2008 are inflatable rigid designs with inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

The Zodiac Pro Open 550 2008 tops out at 120 hp. Engine specs for the Zodiac 350 TC4 2009 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Zodiac Pro Open 550 2008 is rated for 11 passengers, while the Zodiac 350 TC4 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac Pro Open 550 2008 could be the deciding factor.

The Zodiac Pro Open 550 2008 has a documented top speed of 45 mph. Speed data wasn't available for the other model.

Bottom line: Choose the Zodiac Pro Open 550 2008 if your priority is putting more people on the water — it handles 11 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Zodiac 350 TC4 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
