[PSUBS-MAILIST] Alec's new sub

Mon Jun 29 17:10:22 EDT 2015

"A knot or less" and "Manatee" both suggest sluggishness to me, but I think
this little boat will move. My wife is suggesting "Shackleton" since I
really like the fellow and he was a relative. So that one's in the lead,
but I'm still pondering it. If she were a one-person, I would name her
"Batchelors Delight" after a pirate ship that I think had the best name of
all time.  Yesterday I did something I hadn't done in a long time, and
actually looked at a list of baby names. This is fun.
