don't give up the ship
I have nothing to offer regarding the ships mentioned in this post, but I encourage members to continue following this site because you never know what will happen. Sometimes the new information about a ship you knew nothing about will incite your interst and start you on a new quest. Other times (as was the case for me) you will find present in a post something which at first seems only tangentially related to your search but ends up being a very close clue. So, sorry I have nothing to add but encouragement...
Oops! also gratitude to all the members who continue to help perfect strangers in their search for the important stories that make up our collective international and personal nautical heritage.
