Both the Marquis Yachts 500 Sport Coupe 2010 and the Marquis Yachts 520 2009 are semi-displacement designs, both built in fibreglass, so 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 2010 at 49,5 ft versus Marquis Yachts 520 2009 at 51,6 ft. Weight tells a clearer story for trailering families: the Marquis Yachts 520 2009 tips the scales at 56 227 lbs - 11 727 lbs less than the Marquis Yachts 500 Sport Coupe 2010 at 44 500 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.

Both boats are rated for 14 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
