You are duty officer on board a vessel in open sea. The look out is doing work and you are alone on the bridge, presently checking the position in the chartroom. Suddenly you are colliding with a fishing vessel. You will be most to blame for the collision, because of:

You should ask over VHF if there is any vessels in the surronding waters before going to the chart room.

You shall always give the "keep away" signal when doing chart work.

When a ship is lying at anchor in a tidal area using both forward anchors, to what particular aspect should the officer of the watch be paying special attention?

When the ship swings to the tide the direction of swing should be controlled to avoid the anchor cables becoming wrapped round each other.

The ship will become controlled by the tide and the wind will not be allowed to have any effect on the direction the ship lies at anchor.

The two anchors will restrict the ships swing with the tide and the ship may not lie to the prevailing current and wind

The tension on both cables should be similar, to avoid one dragging and all the weight of the ship remaining on the other anchor only.

Experience has shown that the most successful method of double banking (when no tugs used) is:
