Not sure who your ancestor might be but searching just on boat gord ancestry tosses out this one in 1861 as a BOAT GORD LABOURER...

And since it kinda looks like the name isn't exactly right either I chose to search on SP with wildcards of H*T to truly find the right 50 year old chappie in Tradeston....
1861 HUNT THOMAS M 50 TRADESTON GLASGOW/LANARK 644/09 010/09 004
and if you truly viewed the original census you'd quickly see that a boat gord equals a BOAT YARD LABOURER.
If he's not your ancestor then perhaps ancestry calls all the boat yard folk boat gorders?
My best guess...
