Anchor rope + bouy knot. How to?

[Nanu/Nanu]

No mention of the sheepshank knit a good one to know

Sheepshank

Unreliable knot used to shorten a length of rope. With a few possible exceptions, the Sheepshank should never be used. It is only included here because Boy Scouts used to be required to learn it.

This knot is nice to shorten rope but yes completely unreliable.

Not true, I can tie several knots.

Just not the one you need…..
