When two boats share the same hull type — in this case both the Marquis Yachts 500 Sport Coupe 2012 and the Marquis Yachts 690 2010 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?

Size is the most obvious dividing line here. The Marquis Yachts 690 2010 measures 70,0 feet overall (2010), giving it roughly 20,5 additional feet of deck space compared to the Marquis Yachts 500 Sport Coupe 2012 at 49,5 feet (2012). Weight tells a clearer story for trailering families: the Marquis Yachts 500 Sport Coupe 2012 tips the scales at 445 lbs — 351 lbs more than the Marquis Yachts 690 2010 at 94 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
