Anchor safety clip

[Hurricane]

No, never have tied it down. The chances of it self launching are pretty small, it takes quite a bit of effort for me to push it off the bow roller.

Oh - I wouldn't - there is always a first time.
Maybe a big wave - bows go up and crash down - then the anchor could slip on its clutch - there is nothing else holding it.
The next thing could be chain round the props.
