Both the Marquis Yachts 560 2009 and the Marquis Yachts 690 2010 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?

Size is the most obvious dividing line here. The Marquis Yachts 690 2010 measures 70,0 feet overall (2010), giving it roughly 12,6 additional feet of deck space compared to the Marquis Yachts 560 2009 at 57,4 feet (2009). Weight tells a clearer story for trailering families: the Marquis Yachts 690 2010 tips the scales at 94 000 lbs - 32 000 lbs less than the Marquis Yachts 560 2009 at 62 000 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.

For family outings this is probably the sharpest distinction between the two. The Marquis Yachts 690 2010 is rated for 20 passengers, while the Marquis Yachts 560 2009 caps at 16. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marquis Yachts 690 2010 could be the deciding factor.
