Marquis Yachts 720 Fly Bridge 2011 vs Marquis Yachts 720 Tri-Deck 2010 — A Close Look at Two Semi Displacements

When two boats share the same hull type — in this case both the Marquis Yachts 720 Fly Bridge 2011 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?

On paper these two are close siblings in the size department — Marquis Yachts 720 Fly Bridge 2011 at 72,1 ft versus Marquis Yachts 720 Tri-Deck 2010 at 72,1 ft. Weight tells a clearer story for trailering families: the Marquis Yachts 720 Fly Bridge 2011 tips the scales at 1 152 lbs — 1 043 lbs more than the Marquis Yachts 720 Tri-Deck 2010 at 109 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 20 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.

Bottom line: The Marquis Yachts 720 Fly Bridge 2011 and Marquis Yachts 720 Tri-Deck 2010 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Which is the larger boat — the Marquis Yachts 720 Fly Bridge 2011 or the Marquis Yachts 720 Tri-Deck 2010?
The Marquis Yachts 720 Tri-Deck 2010 is the longer of the two at 72,1 feet overall. The Marquis Yachts 720 Fly Bridge 2011 comes in at 72,1 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Marquis Yachts 720 Fly Bridge 2011 or the Marquis Yachts 720 Tri-Deck 2010?
For trailering, the Marquis Yachts 720 Tri-Deck 2010 has the edge at 109 lbs dry weight versus 1 152 lbs for the Marquis Yachts 720 Fly Bridge 2011.

How many people can each boat hold?
The Marquis Yachts 720 Fly Bridge 2011 is Coast Guard rated for 20 passengers, while the Marquis Yachts 720 Tri-Deck 2010 is certified for 20.

Do these boats require an oversize trailer permit to tow on US highways?
Both the Marquis Yachts 720 Fly Bridge 2011 and Marquis Yachts 720 Tri-Deck 2010 share an 18 ft. 4 in. (4.7 m) with gunnel molding beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Marquis Yachts 720 Fly Bridge 2011 and Marquis Yachts 720 Tri-Deck 2010?

Yes — both the Marquis Yachts 720 Fly Bridge 2011 and the Marquis Yachts 720 Tri-Deck 2010 are built by Marquis Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
