When two boats share the same hull type — in this case both the Zodiac 350 TC4 2009 and the Zodiac Pro 850 2011 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 850 2011 tops out at 300 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 850 2011 is rated for 10 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 850 2011 could be the deciding factor.
