The Sea Ray 450 Sedan Bridge 2013 vs Sea Ray Sundeck 290 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 450 Sedan Bridge 2013 measures 45,6 feet overall (2013), giving it roughly 16,4 additional feet of deck space compared to the Sea Ray Sundeck 290 2017 at 29,2 feet (2017). Weight tells a clearer story for trailering families: the Sea Ray 450 Sedan Bridge 2013 tips the scales at 36 602 lbs — 30 131 lbs more than the Sea Ray Sundeck 290 2017 at 6 471 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 480 hp, the Sea Ray 450 Sedan Bridge 2013 has a 100-hp advantage over the Sea Ray Sundeck 290 2017's 380-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 450 Sedan Bridge 2013 carries 375 gallons versus 85 gallons in the Sea Ray Sundeck 290 2017. 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 450 Sedan Bridge 2013 is rated for 13 passengers, while the Sea Ray Sundeck 290 2017 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 450 Sedan Bridge 2013 could be the deciding factor.
