If I remember right, the Cutty Sark has a black hull, right? I assume then that the name would be in a white font. It is very hard to make your own white decals. However, if you can find them in a close-enough font, Archer makes very nice dry transfer lettering. So you can at least do the name and other lettering. The dry transfer lettering, while a bit more work, since you need to apply each letter seperately, look even better than decals when done. Archer has a fair selection of fonts, and a wide range of letter sizes.
