of masts on naval ships are plated, but lattice masts may still exist

of masts will determine their structural integrity for the purpose
of carrying naval equipment and supporting loads from RAS equipment
where fitted.
6.1.3 Areas that
can trap water internally and externally are to be carefully examined
for corrosion.
