In the case of an ASW 24 My friend who weighs 230 lb is well over six feet
has a lead weight of six kilo's or 13.2 lb. installed in the fin.
Each glider has or at least should have provisions to install this type of
weight to make sure the glider flies within the required C of G.

Is it acceptable practice to put lead in a gliders tail to counter the
weight
of a large pilot?
