Marquis Yachts 420 Sport Bridge 2012 vs Marquis Yachts 720 Tri-Deck 2010 — Which Semi Displacement Fits Your Needs?

When two boats share the same hull type — in this case both the Marquis Yachts 420 Sport Bridge 2012 and the Marquis Yachts 720 Tri-Deck 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 720 Tri-Deck 2010 measures 72,1 feet overall (2010), giving it roughly 28,5 additional feet of deck space compared to the Marquis Yachts 420 Sport Bridge 2012 at 43,6 feet (2012). At 32 lbs and 109 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The Marquis Yachts 420 Sport Bridge 2012 carries a rated maximum of 174 hp. Engine data for the Marquis Yachts 720 Tri-Deck 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Marquis Yachts 720 Tri-Deck 2010 carries 13 gallons versus 3 gallons in the Marquis Yachts 420 Sport Bridge 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Marquis Yachts 720 Tri-Deck 2010 at 72,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The Marquis Yachts 420 Sport Bridge 2012 at 43,6 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.
