Louie 13 contacted me via PM with another John Docherty . Hopefully this is the correct one.
The ticketing system was widely unpopular and is recorded sometimes incorrectly, in three different series 1835-1844, 1845-1854 and 1853-1856.
This record is from the second series (BT114) which is the most difficult to interpret.
For 1847
outward. The letters 9/52 could be the ships Port Rotation number. Unfortunately no "Key" exists to link the number to a ships name.
The number 44 tells us she was registered in Glasgow and John Docherty sailed from Greennock (48) on the First of June 1847.
I cannot read the comments in the "Home" column.
The only way to find out which vessel it was is to look at the Crew Agreements of Glasgow registered vessels 1847. These are stored in Kew in the series BT98.

If I am correct about the Port Rotation number, this may be recorded on the crew agreement rather than look for a name.
A search of the Greenock/Glasgow newspapers around the 1/6/1847 may help narrow things down.
