Nautical Term: Mast hole

Definition of Mast hole

A mast hole is a larger diameter opening in the deck specifically designed to house a mast. This hole is larger than the mast itself, allowing for the installation of two rows of founded wedges. These wedges securely hold the mast in place, preventing it from shifting or becoming dislodged during rough seas or strong winds.

For example, during the construction of a tall ship, the carpenters would carefully measure and mark the location of the mast hole on the ship’s deck. They would then cut out the circular opening using heavy-duty tools such as chisels and hammers. After the hole was cut, the carpenters would install the two rows of founded wedges to securely hold the mast in place once it was raised.
