The 480 Sedan Bridge (480DB) was in production from 1998 through 2004. It was changed very little during that run, but some of the changes include the square-cornered hard-top being replaced by a more rounded one, the swap of the salon sliding door from starboard to port, TV cabinet changes, salon and bridge HVAC re-work, misc trim and feature updates etc. Available engines included DD 6V-92's, Cat 3196, Cummins QSM-11 and MAN 700's. My favorite aspect of the 480DB, aside from what I think are clean, good looks, is the fact that visibility from the helm is just about perfect. It makes it seem like a much smaller boat than it is.
The 500 Sedan Bridge came out of a fresh mold in 2005 to replace the 480. The general layout remained the same, but the finishes were in the newer style. The 3rd stateroom has a smaller feel than that in the 480, but it has regular bunks instead of the odd perpendicular configuration. The galley became a step-down, which one could also argue makes the salon & galley area feel larger.
The 52 Sedan Bridge (52DB) is the re-named 500DB, but there were some tweaks to that too, most notably the galley moving a stop closer to the salon level (freeing some space in the 3rd stateroom), and a re-work of the upper transom assy.
