Esther,
As Tracy said in her 1st message, Titanic's 13
saved lifeboats were likely re-used on other White
Star ships. There is a picture in "Titanic - An
Illustrated History" which shows
Olympic shortly
after the disaster with a handful of lifeboats in
the foreground. It is possible that the boats were
transported back to England and re-installed
perhaps even on the
Olympic. They were only used
once and in good shape. With the name plates
removed, no one would ever know if they were new
or from the Titanic. Officials would not have
discarded a good boat, as it would have been a
waste of money to do so, especially then in a
non-disposable society. Those boats the Carpathia
couldn't haul back to New York on her decks were
deliberately sunk for safety purposes.
Collapsibles A and B were left adrift, as they
never made it to the Carpathia. A was picked up
some time later and hauled ashore. As far as I
know, B, damaged during the sinking, drifted and
probably eventually rotted somewhe
