EQUIPMENT
The bat
The offi cial bat is made of wood, bamboo, plastic, graphite, metal, magnesium or any other composite
material. It must either be round or three sided. If the bat is round it may not be more that 60 mm in
diameter and it may not be longer than 860 mm or 1.08 kilogram in weight. In addition, in fast pitch, a
“drop” of no more than 12 is allowed. A drop is calculated by taking the length of the bat in inches and
subtracting the weight in ounces.
The ball
The size of the ball varies according to the classifi cation of play. In International play the circumference
is 300 mm and the weight is between 6 ¼ and 7 ounces and where the circumference is 280 mm the
weight is between 5 7/8 and 6 1/8 ounces.
Gloves
All defensive players wear fi elding gloves that have webbing between the thumb and forefi nger. The fi rst
baseman and the catcher may wear mitts. Mitts have additional padding and do not have fi ngers.
Construction of the soft ball fi eld
The substrate construction of both the infi eld and the outfi eld are the same. The difference in the two is
that the infi eld does not get grassed and the earth surface is compacted and levelled with the grassed
outfi eld.
The construction of the grassed outfi eld is as follows:
Grassed outfi eld
The general specifi cation of the sub-surface may vary dependant on site conditions and should be in
terms with a Civil Engineers specifi cations. The general specifi cation may, however, be described as
follows:
• Remove all topsoil. Remove all topsoil and level earth platform to correct site development
levels with particular emphasis on natural sub-soil drainage.
• Rip and compact in-situ earth to 93 % modifi ed AASHTO.
Softball
• Install sub-surface drainage comprising 110 mm diameter agricultural drains placed in 450
x 600 mm deep herring bone drainage system at 6 metre intervals and to entire perimeter
of the cricket fi eld.
• Sub-surface drains to be lined with a “Bidum” Hessian layer and fi lled in with 19 mm
crusher run stone.
• Sub-Surface drains to connect at the lowest point to a storm water catch pit which should
