The Marquis Yachts 40 SC 2008 vs Marquis Yachts Tri-Deck 2009 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
The power gap is worth calling out. Rated to 1 676 hp, the Marquis Yachts Tri-Deck 2009 has a 1 076-hp advantage over the Marquis Yachts 40 SC 2008's 600-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Marquis Yachts Tri-Deck 2009 carries 33 gallons versus 3 gallons in the Marquis Yachts 40 SC 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Marquis Yachts Tri-Deck 2009 could be the deciding factor.
Bottom line: Choose the Marquis Yachts Tri-Deck 2009 if your priority is putting more people on the water — it handles 21 passengers and at 72,0 ft it has the deck room to back that rating up comfortably. The Marquis Yachts 40 SC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
