When two boats share the same hull type — in this case both the Marquis Yachts 500 Sport Coupe 2011 and the Marquis Yachts Marquis 50 2008 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?

On paper these two are close siblings in the size department — Marquis Yachts 500 Sport Coupe 2011 at 49,5 ft versus Marquis Yachts Marquis 50 2008 at 51,0 ft.
