Choosing an Anchorage

A good anchorage offers shelter from the wind and sea, adequate depth (allowing for tidal range), good holding ground (sand or mud), enough room to swing, and a clear approach free from h...

  • Shelter from wind and sea
  • Adequate depth for tidal range + vessel draught

Anchor Types

Different anchor designs work better in different seabed types. The CQR (plough) anchor performs well in sand and mud and sets reliably. The Bruce (claw) anchor is good all-round and self...

  • CQR (plough) — reliable in sand and mud, widely used
  • Bruce (claw) — good all-round, self-rights easily

Anchoring Technique

Approach the chosen spot heading into the wind (or tide, whichever is stronger). Stop the boat and lower the anchor — don't throw it. Pay out the cable (chain or warp) as the boat drifts...

Weighing Anchor

To weigh (recover) the anchor, motor slowly forward while retrieving the cable. This takes the load off the cable and makes retrieval easier. When the cable is vertical (the anchor is dir...

  • Motor forward slowly while retrieving cable
  • Pull vertically to break the anchor free

Advanced Anchoring Techniques

Kedging is the technique of using an anchor to move the boat rather than to hold it in position. A kedge anchor is rowed out in the dinghy (or thrown ahead if close enough) and dropped, t...

  • Kedging — using an anchor to haul the boat forward or off a grounding
  • Strong conditions: increase scope to 8:1 (chain) or 10:1 (rope)

Yachtmaster Offshore Standard

Anchorwork at Yachtmaster level is not just recall. The answer has to show command judgement, evidence quality, margin, and a fallback if the first plan stops being safe.

  • State the evidence you trust and the evidence you distrust.
  • Name the margin that makes the plan defensible.

Advanced Scenario Check

Decision pressure: Leaving later will be harder, so the Yachtmaster decision must come before the situation is forced.

  • Apply Considerations when anchoring to a changed real-world situation.
  • Separate fact, estimate, and assumption.
