chainplate

The pole can be mounted onto the backstay chainplate.

A chainplate is a metal plate used to fasten a shroud or stay to the hull of a sailboat.

Although this type of chainplate is sometimes criticised, there is no recorded instance of a dismasting, and Rogers claims reinforcing this system would have no impact on safety.

One end of the chainplate is normally fastened to a turnbuckle which is connected to the shroud or stay, whereas the remainder of the chainplate normally has multiple holes that are bolted to the hull.
