A tall ship is a large traditionally rigged sailing vessel. Popular modern
tall ship rigs include topsail schooners, brigantines, brigs and barques.

Traditional rigging may include square rigs and gaff rigs, with separate
topmasts and topsails. It is generally more complex than modern rigging,
which utilizes newer materials such as aluminum and steel to construct
taller, lightweight masts with fewer, more versatile sails.

The term tall ship has come into widespread use in the mid-20th century with
the advent of The Tall Ships' Races.

While Sail Training International (STI) has extended the definition of tall
ship for the purpose of its races to embrace any sailing vessel with more
than 30 ft. (9.14 m) waterline length and on which at least half the people
on board are aged 15 to 25, this definition can include many modern sailing
yachts, so for the purposes of this article, tall ship will refer to those
vessels rated as class "B" or above (Fore and aft rigged vessels between 100
to 160 feet in length, and all square rigged vessels).

The well-known poem "Sea Fever" by the English Poet Laureate John Masefield
contains the line "And all I ask is a tall ship and a star to steer her by",
inspired by the poet's experience of serving in sailing ships during his
youth.[1]

And talking of being picky, once aboard a sailing ship, you learn the
"ropes" not the "lines".
