Detailed Evaluation & Buyer Recommendation

Marquis Yachts Tri-Deck 2009 vs Marquis Yachts 50 LS 2007 — Same Brand, Different Boat

The Marquis Yachts Tri-Deck 2009 vs Marquis Yachts 50 LS 2007 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 961-hp advantage over the Marquis Yachts 50 LS 2007's 715-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 6 gallons in the Marquis Yachts 50 LS 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Marquis Yachts Tri-Deck 2009 is rated for up to 21 people. Passenger data for the Marquis Yachts 50 LS 2007 wasn't available.

Bottom line: The Marquis Yachts Tri-Deck 2009 at 72,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Marquis Yachts 50 LS 2007 at 51,0 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.
