The Sea Ray 240 Sundeck 2007 vs Sea Ray Sedan Bridge 390 2010 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 380 hp, the Sea Ray Sedan Bridge 390 2010 has a 60-hp advantage over the Sea Ray 240 Sundeck 2007's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray Sedan Bridge 390 2010 carries 300 gallons versus 65 gallons in the Sea Ray 240 Sundeck 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 240 Sundeck 2007 is rated for 12 passengers, while the Sea Ray Sedan Bridge 390 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 240 Sundeck 2007 could be the deciding factor.
