When two boats share the same hull type — in this case both the Nor-Tech 4000 Roadster 2012 and the Nor-Tech 5200 Roadster 2012 are catamaran designs with composite 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 Nor-Tech 5200 Roadster 2012 is rated for 14 passengers, while the Nor-Tech 4000 Roadster 2012 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nor-Tech 5200 Roadster 2012 could be the deciding factor.
