If you mean the Cutty Sark Tall Ships Race you're in for a treat if your harbour & events people have done it right. Cutty Sark Tall Ships were in Greenock in 1999 and this was one of the best events / festivals I've ever seen (and I've been to a few!)The atmosphere was sooo terrific and people still talk about it. The bid from here to bring the event back next time lost out to Liverpool (narrowly) Take time off work to get to everything you can!
