When two boats share the same hull type — in this case both the Zodiac 420 TC4 2009 and the Zodiac Bayrunner Pro Series 2010 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?

For family outings this is probably the sharpest distinction between the two. The Zodiac 420 TC4 2009 is rated for 6 passengers, while the Zodiac Bayrunner Pro Series 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Zodiac 420 TC4 2009 could be the deciding factor.
