The replacement for the Ambrose Lighttower looks something like your photograph.

On the CC-USLHS trip to the Chesapeake Light Tower, we were told the the tower is still structural sound, and will remain in place for another five years. Unfortunately by photos are not digital and I have no scanner. Maybe Chesapeake Bryan can post some.

I believe the Savannagh light tower was also struck by a ship several years ago, and the captain didn't even report the accident to the USCG.
