Iron model of a ‘securitas’ anchor.
This anchor does not have a normal stock, but is fitted instead with a short stock set perpendicularly to the arms, and the flukes are set in the same plane as the arms. Arms and stock turn in the forked end of the shank, the stock forces the flukes into the ground. By means of a rope attached to a shackle at the crown, the stock can be set in the correct position and the anchor can also be raised. The top of the shank has a shackle.
The ‘securitas’ anchor was an improved version of Hawkins’ patent anchor and was patented in the Netherlands by L.J. Vonk in The Hague in 1853; the shape of the anchor stock was changed. It proved satisfactory as a day anchor on trials with Wassenaer, but would not hold in mud, as it transpired later with Zoutman in Japan. It was also difficult to cat and to fish.
Scale (estimate) 1:5.
