Almost all the AHTS I have found pictures of have anchor pockets as does the variant above that inspired me to be a bit more adventurous. So here I am marking and cutting for them as it's easier for them to be sorted before installing the decks. These are the first design which are 25mm wide and 12mm high. In the later evolution (after making the back-boxes and trial fitting them and an anchor) the cutouts actually ended up 22mm tall.
