Sheave (12A16)
This heavily eroded sheave was found to the west of the Coronation weck site off Penlee Point. All that remains is the central portion of the sheave that was protected by the triangular copper alloy coak fitted in the centre that was used as a bearing surface for the central spindle. The lower image shows a similar but nearly intact sheave found in the Hamoaze.
The sheave would originally have been mounted within a large pulley block and would have been used as part of the rigging on the vessel. Blocks were also used for gun tackle but the block that this sheave came from is probably too large for that purpose.
