In many models of 17th & 18th ships displayed with catted anchors the anchor line ends in a bight which is formed around a ring on the anchor stock. The anchor line is then led through a hawse hole into the ship. No provision is made for removing the anchor line from the anchor although this was apparently done so the line could be pulled entirely inboard and the hawse hole plugged to prevent water from entering. Does anyone know how the anchor connection was actually made (e.g. large shakle? split ring?) or have examples, diagrams, etc. Any comments would be much appreciated.
