Running Moor
Anchoring with two anchors by laying the first anchor while making way ahead, then dropping the second after veering chain.
In practice
Used in restricted-swinging anchorages; needs accurate timing of letting go each anchor. Bow team coordinates with the bridge via VHF or hand signals.
Regulatory detail & full definition
Anchoring procedure in which the first anchor is laid while the ship is making way ahead, then the ship runs forward over the laid anchor while paying out chain, drops the second anchor, and then heaves on the first while veering on the second to balance the catenaries. The result is two anchors on the same line of bearing with the ship moored between them. The technique is used in restricted swinging room and where strong tides reverse direction. Skill in chain handling and timing is the critical operational skill.
