Detailed Evaluation & Buyer Recommendation
Sea Ray 40 Motor Yacht 2007 vs Sea Ray 680 Sun Sport 2005 — Same Brand, Different Boat
The Sea Ray 40 Motor Yacht 2007 vs Sea Ray 680 Sun Sport 2005 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.
Size is the most obvious dividing line here. The Sea Ray 40 Motor Yacht 2007 measures 41,0 feet overall (2007), giving it roughly 34,0 additional feet of deck space compared to the Sea Ray 680 Sun Sport 2005 at 7,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray 40 Motor Yacht 2007 tips the scales at 265 lbs — 190 lbs more than the Sea Ray 680 Sun Sport 2005 at 75 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.
The Sea Ray 40 Motor Yacht 2007 carries a rated maximum of 407 hp. Engine data for the Sea Ray 680 Sun Sport 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 3 gal and 1 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 680 Sun Sport 2005 is rated for 21 passengers, while the Sea Ray 40 Motor Yacht 2007 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 680 Sun Sport 2005 could be the deciding factor.
Bottom line: Choose the Sea Ray 680 Sun Sport 2005 if your priority is putting more people on the water — it handles 21 passengers and at 7,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 40 Motor Yacht 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
