The Sea Ray Fly 460 2018 vs Sea Ray Sedan Bridge 450 2012 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.
On paper these two are close siblings in the size department - Sea Ray Fly 460 2018 at 46,8 ft versus Sea Ray Sedan Bridge 450 2012 at 45,0 ft.

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.

Rated to 550 hp, the Sea Ray Fly 460 2018 has a 70-hp advantage over the Sea Ray Sedan Bridge 450 2012's 480-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 375 gal and 375 gal - so range won't be a tiebreaker here.
