Modern arbalists shoot crossbows markedly different from medieval artillerymen. Current-day target crossbows must conform to various limitations according to the governing body under which the shoot or
tournament is taking place. Firstly,
GNAS requires that arbalists shoot at targets separate from archers. Both the World Crossbow Shooting Association (WCSA) and GNAS require that the draw weight maximum be 95 lbs and that the minimum bolt (arrow) length be 12 inches. These organizations differ, however, in allowable maximum bolt length, GNAS citing 15", WCSA 18". They also disagree as to whether metal prods can be used; GNAS says no, WCSA says yes (with restrictions). Both require that the bolts shall be
fletched, GNAS imposing an additional constraint of the
number of fletchings (three). ==Classification==
