As forecast weather deteriorates while a vessel is at anchor, what should change regarding the main engine's readiness state?

A. The main engine should be brought to a state of readiness appropriate to the deteriorating conditions and proximity of hazards (e.g. reduced notice for starting, or main engine on standby/running) well before conditions actually require its use — engine readiness must anticipate a deteriorating trend, not be arranged only after dragging or an emergency is already underway

B. The engine should always remain on the same readiness state regardless of weather forecast or trend

C. Engine readiness is irrelevant while at anchor since the anchor alone is responsible for holding the vessel in position

D. Engine readiness should only be increased after the anchor has already started dragging, not before

A. Scope refers only to the type of anchor fitted and has nothing to do with chain length

B. A shorter scope always provides better holding power than a longer scope in all conditions

C. Scope is irrelevant to holding power and only affects swing radius

D. Scope is the ratio of chain length paid out to the depth of water; a greater scope lays more chain along the seabed, reducing the angle of pull on the anchor itself (keeping the pull more horizontal), which significantly improves the anchor's ability to dig in and hold rather than being lifted or dragged by a more vertical pull

A. A high-holding-power anchor is designed and tested to achieve significantly greater holding power for a given weight compared to a standard stockless anchor, allowing either a lighter anchor for the same holding requirement or better holding for the same weight — the trade-off can include different digging-in behaviour or seabed type sensitivity depending on design

B. Anchor type has no bearing on holding power, only chain scope matters

C. All anchor types provide identical holding power regardless of design, with weight being the only relevant factor

D. Stockless anchors always provide more holding power than any HHP design, making HHP anchors obsolete
