Mass of size classes was never given in SG, but it was given in FT for
us
vac heads. In MT, it gave the ratio of cargo size points (in SG terms)
per
mass, and from this I worked out each size class in SG equals 8 tonnes,
so a
class 5 MBT masses 40 tonnes (unless you are using the
multipul/sectional
rules, can`t remember the exact name, don`t have the book handy).
