Talk:deep six
Add topicFrom a nautical point of view you have to keep in mind two things:
1. Things aren't normally thrown overboard from a ship. The concept of a ship is to bring things over the water. So there is no idea to measure the difficulty to recover them.
2. It is fundamentally important for a ship to have always enough water beneath the keel. Measuring the depth of the water is done to asure exactly this.
The deep six call might be a threshold to be even more attentive because it might become critical for the ship if the water depth would further reduce. So things are getting bad "by deep six" and worse "by deep five" or even worst "by deep four".
Before the ship hits the ground, the last critical action would be to throw things - preferably heavy things - overboard, to keep the ship going and to avoid its destruction on the ground.
That is where the meaning comes from, to get rid of something, to throw away something, to stop something from getting worse. 193.24.32.58 22:20, 16 August 2022 (UTC)
