Flags at Sea - Jack

“Jack” is the name given to the “Flag” flown on a small vertical spar (pole) at the stem or on the bowsprit of a warship.

E.M.C. Barraclough, the internationally renowned vexillologist writes ‘although at first ‘Jacks’ were flown from the mast-head of a ship, it soon became the practice to fly them from the ‘sprit-mast’ which was fixed to the bowsprit. It was often been thought that the “flag” is called a “Jack” because it flies from the ‘Jackstaff’, but actually the ‘staff’ is called a “Jackstaff” because the “Jack Flag” flies from it. Likewise, the British “Union Flag” is most often wrongly referred to as “Union Jack”

 

 

Most countries use the diminutive of their National flag as ‘Jack’

 

 Scandinavian countries State flags and Jacks are 'swallow-tailed' or 'split' at the fly.

 

 

 Some countries have/had a ‘historic’ or other special design ‘Flag’ for use as ‘Jack’.
