When two boats share the same hull type — in this case both the Marquis Yachts 420 Sport Coupe 2009 and the Marquis Yachts 600 2012 are semi displacement 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?
