Detailed Evaluation & Buyer Recommendation
Marquis Yachts 55 LS 2007 vs Marquis Yachts Marquis 70 Tri-Deck 2008 — Which Semi Displacement Fits Your Needs?
When two boats share the same hull type — in this case both the Marquis Yachts 55 LS 2007 and the Marquis Yachts Marquis 70 Tri-Deck 2008 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?
The power gap is worth calling out. Rated to 1 676 hp, the Marquis Yachts Marquis 70 Tri-Deck 2008 has a 901-hp advantage over the Marquis Yachts 55 LS 2007's 775-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 55 LS 2007 carries 836 gallons versus 13 gallons in the Marquis Yachts Marquis 70 Tri-Deck 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Marquis Yachts Marquis 70 Tri-Deck 2008 at 72,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Marquis Yachts 55 LS 2007 at 57,0 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.
