6.1.1 A primary assumption made in this chapter
is that high-speed craft will only need an anchor for emergency purposes.
6.1.2 The arrangements for anchoring, towing and
berthing and the local craft structure, the design of the anchor,
towing and berthing arrangements and the local craft structure shall
be such that risks to persons carrying out anchoring, towing or berthing
procedures are kept to a minimum.
6.1.3 All anchoring equipment, towing bitts, mooring
bollards, fairleads, cleats and eyebolts shall be so constructed and
attached to the hull that, in use up to design loads, the watertight
integrity of the craft will not be impaired. Design loads and any
directional limitations assumed shall be listed in the craft operating
manual.
6.1.4 Under any operating load up to the breaking
strength of the anchor cable or mooring lines, the loads on the bitts,
bollards, etc., shall not result in damage to the hull structure that
will impair its watertight integrity. A strength margin of at least
20% above the resultant load based on the minimum specified breaking
strength of the relevant cable or warp shall be required.
