20.2.1 The Tabulated values for anchor masses
refer to High Holding Power anchors. Anchors of other designs may
be accepted based on the stated holding power.
20.2.2 When a fisherman type of anchor is provided, the
mass given in Table 1 should be increased by 75% but the diameter of the anchor cable need
not be increased.
20.2.3 For vessels with an unusually high windage, due to
high freeboard, a large rig, large deckhouses or superstructures, the mass of the anchor
and the anchor cable diameter should be increased above that required in Table 1 to correspond to the increased wind loading. The increase in anchor
mass and corresponding cable strength is to be to the satisfaction of the Certifying
Authority.
20.2.4 For vessels of unusual or non-conventional
ship form (including pontoon barges) the anchor and cable size should
be to the satisfaction of the Certifying Authority.
20.2.5 Anchors are to be rigged ready for use.
Only where the particular operating patterns dictate may the anchor
be left unready, e.g. Pilot boat duties.
20.2.6 The design of the anchor is to be acceptable
to the Certifying Authority.
20.2.7 Stainless steel and aluminium anchors will
be separately considered dependent upon the test loads for which the
anchor has been designed.
