If sailing at night, in particular, it is such a good idea to have these hard points alongside the companionway
. If you are (rudely) awoken in the wee small hoursto go on watch, from a deep sleep, and you stagger upstairs to go on deck
, you will most likely be groggy, uncoordinated and a little bit disorientated for a few minutes before you wake up fully, get your night vision, etc. This is when you are most vulnerable to making a mistake. Clipping your harness tether onto a hard point before even coming up from down below is definitely a great idea.
