The Sea Ray 340 Sundancer 2006 vs Sea Ray Sundancer 460 2017 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 Sundancer 460 2017 measures 46,8 feet overall (2017), giving it roughly 9,8 additional feet of deck space compared to the Sea Ray 340 Sundancer 2006 at 37,0 feet (2006). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 460 2017 tips the scales at 36 208 lbs — 36 062 lbs less than the Sea Ray 340 Sundancer 2006 at 146 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 power gap is worth calling out. Rated to 526 hp, the Sea Ray Sundancer 460 2017 has a 151-hp advantage over the Sea Ray 340 Sundancer 2006's 375-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 Sundancer 460 2017 carries 375 gallons versus 225 gallons in the Sea Ray 340 Sundancer 2006. 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 Sundancer 460 2017 is rated for 14 passengers, while the Sea Ray 340 Sundancer 2006 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 Sundancer 460 2017 could be the deciding factor.
