I am also building the Thermopylae. I think I built the Cutty Sark 3 times through college in the 60s. A couple of years ago I bought both Thermopylae and Cutty Sark on eBay before prices skyrocketed. I ended up using both kits to build one ship. Some of the parts, especially masts, we’re warped. The Cutty Sark masts weren’t any better and had parts only partially formed. I checked on line for a fix after my own attempts were dismal. I worked up a procedure that works reasonably well. Fill a pan with the hottest water you can get out of your faucet. Place the part in the water and leave for about one minute. This softens the plastic enough to bend it with your fingers. I tried it on a spruce runner and could bend it double without breaking. I used a cutting mat printed lines to get the part as close to straight as possible. Once you’re satisfied it is straight enough Leave it on the mat and clamp it in position until the plastic cools ( several hours). If you don’t clamp it the piece will return to its original shape. I found I had to do this several times before I was satisfied. It not perfect, but close enough to finish straightening it out with shrouds and stays when you rig it.
