You definitely went overboard on the Watchtowers. You were frequently drawing 2 or even 1 from them, and drawing 1 means that it might as well not be there. Your opponent only had one Watchtower, but it did lots of work thanks to Inns. If you adopt a strategy similar to HiveMind's suggestion/your opponent's strategy, you would likely win because your opponent kept on hitting $9 and $10.
I'm wary of Ghost Ship because of how much Watchtower would stop it, especially with Fishing Village + Inn out.
Then again, Ghost Ship + Rabble sounds incredibly mean...
Ghost Ship + Rabble is a double-edged sword. You might just end up discarding two of their Coppers, especially if they have an Inn or Watchtower in hand (since they have nothing to lose by putting two Coppers on top). Also, I initially parsed your name as Tit-and-rake.
