I have strongly disagreed with the recommendation to start with simple one or two masted rigs. My belief is that you should start with a ship that interests you instead. You are far more likely to finish it. Author Wolfram zu Mondfeld, Historic Ship Models agrees. His advice is to find one that is attractive enough to you that you will put in the necessary effort to stick with it.
Keep in mind that the rigging plans for most of the following models are simplified, so pick which ship you like. These simplified plans will enable you to get a feel for both standing and running rigging. As you develop your skills you can become more elaborate. There are many books about rigging that could be very helpful to you.
There are many kits in plastic. Most are out of production. Manufacturers like Airfix once produced a nice line of ships of the line like HMS Victory, HMS Prince, and HMS Royal Sovereign. They also produced the British race built Galleon Revenge, the Golden Hind, Mayflower, the HMS Endeavor, HMAV Bounty, the sail/steam Great Western, Discovery, Cutty Sark, and Flying Cloud.
Revell also has a very extensive line of discontinued sailing ships. Stay away from their kit of the HMS Beagle and Thermopylae because the bears no resemblance to the real ship. Their other ships are quite good.These include USS Constitution in three scales, HMS Victory, Santa Maria, Nina, and Pinta, Charles W. Morgan, Cutty Sark, Great Eastern, Batavia, and others.
Lindberg still manufactures several as so-called "Pirate Ships". However, these models are really the French Frigate La Flore, the Wappen von Hamburg, the HMS Royal Sovereign, and French Le Saint Louis.
Heller probably has the largest selection but about half of their ships are fictional. Zvesda is newly developing a sailing ship line but these are quite small at 1/350 scale.
I recommend searching on sites like eBay. These kits are readily available there. I am a big fan of the Airfix line. The hardest thing with them are the elaborate paint schemes.
