Notes:
|
|
|
1.
|
The anchor sizes given are for high holding power (HHP)
types.
|
|
2.
|
When a vessel has unusually high windage due to any
combination of high free-board, large superstructure or deck equipment outfit,
the mass of anchor given above shall be increased to take account of the
increase in wind loading.
For vessels of unusual or
non-conventional ship form (including pontoon barges) the anchor size shall be
to the satisfaction of the Administration.
The diameter of the
anchor cable shall be appropriate to the increased mass of anchor.
|
|
3.
|
Chain cable diameter given is for short link chain. Chain
cable should be sized in accordance with ISO 4565:1986 - Anchor chains for
small craft, or equivalent.
|
|
4.
|
The rope diameter given is for nylon construction. When
rope of another construction is proposed, the breaking load should be not less
than that of the nylon rope specified in the table.
|
|
5.
|
When anchors and cables are manufactured to imperial
sizes, the metric equivalent of the anchor mass and the cable diameter shall
not be less than the table value.
|
|
6.
|
Lwl is the waterline length of the vessel when the vessel
is floating at the assigned free-board draught.
