 The bilander is a two-masted vessel, the foremast carrying square rigs on all of its yards and its taller mainmast having a long lateen mainsail yard with corresponding trapezoidal sail and rig inclined at about 45° with square rigs on the yards above that, the lowermost secured at the corners by a crossjack.The design was popular in the Mediterranean Sea as well as around New England in the first half of the 18th century but was soon surpassed by better designs.It is considered the forerunner of the brig.
