Marquis Yachts 500 Sport Coupe 2011 vs Marquis Yachts 720 Tri-Deck 2012 — Which Semi Displacement Fits Your Needs?

When two boats share the same hull type — in this case both the Marquis Yachts 500 Sport Coupe 2011 and the Marquis Yachts 720 Tri-Deck 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?

Size is the most obvious dividing line here. The Marquis Yachts 720 Tri-Deck 2012 measures 72,1 feet overall (2012), giving it roughly 22,6 additional feet of deck space compared to the Marquis Yachts 500 Sport Coupe 2011 at 49,5 feet (2011). Weight tells a clearer story for trailering families: the Marquis Yachts 720 Tri-Deck 2012 tips the scales at 1 202 lbs — 757 lbs less than the Marquis Yachts 500 Sport Coupe 2011 at 445 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.

Bottom line: The Marquis Yachts 720 Tri-Deck 2012 at 72,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Marquis Yachts 500 Sport Coupe 2011 at 49,5 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
