It all depends on HOW you revive a thread.
If it were me running the site - I'd combine some things here.
There's a lot of duplication. In fact, I SEARCHED first (which is the proper etiquette on nearly every site on the planet it seems) for something about a school. I didn't actually find any threads.
After I started the new thread, suddenly some more threads showed up. I suggested the three be combined regardless of the dates on the threads, since the information in each was slightly different in regards to the same place. It helps folks LOOKING for information to FIND the information.
Responding to a years-old message though, to go sailing might not be helpful
