Both the Marquis Yachts 690 2011 and the Marquis Yachts 720 Tri-Deck 2011 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 690 2011 at 70,0 ft versus Marquis Yachts 720 Tri-Deck 2011 at 72,1 ft. Weight tells a clearer story for trailering families: the Marquis Yachts 720 Tri-Deck 2011 tips the scales at 120 200 lbs - 26 200 lbs less than the Marquis Yachts 690 2011 at 94 000 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.
