It seems to be a bit of both. The Google software clearly "knows" that this is a RIB/boating site in general, but it does serve ads related to individual threads too.
It's dynamic, and can change from view to view. Sometime it takes a while to catch up with the specific content, so you may see RIB related ads initially before it tunes into the actual thread. At the moment I am seeing ads for "Living trusts" which are indeed related to death.
A thread devoted to sausages
eventually brought up adverts for sausage making kits, but after a while it changed back to RIB adverts.
At the moment I am mostly seeing adverts for magnetic climbing walls and dolls houses. Not quite sure where they're coming from!
