While we work on updating the filming locations for the final few episodes of Season 4, we'll drop a fun tidbit today:
During the stunning finale, we were pleasantly surprised to see the
Searcher appear on Lost as Penelope Widmore's rescue boat. This boat in real life is exactly the kind of boat Penny would use to find Desmond.
Not Penny's Boat:
The boat really is called the Searcher, and is a luxuriously appointed 96 ft research vessel owned by Dr. Jon Littenberg. Littenberg used to own a smaller boat, with which he occasionally helped marine scientists conduct their research. Eventually he decided change his life path by purchasing a former luxury yacht and converting it into a research vessel and home, in order to facilitate research full time through his nonprofit the Medical Foundation for the Study of the Environment (MFSE).

Perhaps most famously, the Searcher was recently used by none other than
Jean-Michel Cousteau in a voyage to Kure in the Northwest Hawaiian Islands (See the
PBS Special).
This effort culminated in President Bush's June 2006 establishment of the Northwest Hawaiian Islands area as a National Monument, the largest protected marine area in the world (
press release).
So, following the Kahana (see our page
here), this is the second boat that retains its real-life name when shown in Lost. In a similar vein, we'll soon cover real-life filming locations this season that were depicted as themselves in Lost. There are at least three. Do you think you know what they are? Stay tuned!
