This is a bygone era, but one that refuses to totally die out.  There are tallship cruises available all over the world, and many lighthouses, though no longer in use because of GPS technology, still have many tourists to view the various lighthouses and study their histories, which dates back to ancient Greek times.  That great city, Alexandria, in its day had had a lighthouse to guide the ships during storms or through the fog.

Tallships & Lighthouses

A lens, called a fresnel, to a lighthouse concentrates and increases the power of the light, and points it in one direction.
Gaff rigs are sailing rigs that help fore and aft sails to be hoisted in a four-cornered manner rather than triangular. This assists a sailing ship in sailing more effectively.

Tall Ships typically fall under the category of sailing ships, which are usually wind powered vessels with at least three masts. Tall ships may or may not have three masts and can even include yachts, brigs and barques. Schooners were made popular because of their speed and manueverability.
