When two boats share the same hull type — in this case both the Navigator Yachts Navigator 5100 2013 and the Navigator Yachts Navigator 6200 2010 are deep vee designs with fiberglass 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?
