It is not clear whether these wooden pulley sheaves were a pair or from single sheave pulleys. Generally made from ash (Fraxinus), hickory (Carya) in the case of North America, or Lignum vitae. Lignum vitae, Latin for 'wood of life', is a trade wood, also called Guayacan or Guaiacum from the trees of the genus Guaiacum. The trees are indigenous to the Caribbean and the northern coast of South America and have been an important export crop to Europe since the beginning of the 16th century due to its extraordinary combination of strength, toughness, and density. It was also considered to have self lubricating properties. Ash though tough and elastic is prone to wet rot. Roller bushes were also introduced during the 1880s to reduce friction on the sheave pin. A sheave's size depended mostly on the rope it handled, the higher up the rigging the block was, and the lighter the ropes, the smaller they were. Sheaves also shrank in size as rope quality improved over time, and the introduction of iron parts also contributed to this process. However, many ships continued to use larger blocks due to their making the work easier and therefore requiring less crew to operate.This item was found along with a wooden belaying pin (MAS-D100032) and a marble tile (MAS-D100050).WATER CRAFT36391032/173MAS2017-03-14T00:00:00ZSHIPWith finder2017-03-14T07:28:01Z2017-09-26T13:21:53Z49214283115PAS57C96ECD001E82PAS57C96ECD001E822MAS MASMASWood11988UncertainFairPOST MEDIEVALx41047NINETEENTH CENTURYx41047DivingSubmitted as wreck to the Receiver of WreckIMG_3921.JPG164images/MASABB2017-11-06T18:19:33.525Zfinds-3232MAS-D100032WATER CRAFT EQUIPMENTPOST MEDIEVALA wooden belaying pin, approximately 0.4 m in length.
Belaying pins are either solid metal or wooden objects used on sailing ships to secure the running rigging. They are still seen today on traditional square rigged ships and replica vessels. More modern sailing vessels have tended to replace them with fixed cleats. Their design has little changed, comprising a rounded handle and cylindrical shaft of varying length and thickness, dependant on the workload placed on it. The shaft would fit into holes in pinrails, which lined the inside of the bulwarks around the base of the ship's mast, or a fife rail, which was a free-standing rail set on posts to hold the belaying pins to secure the ship's halyards. The ropes or lines would be wrapped around the pin in a figure of eight pattern to secure them. Similarly designed pins, known as thole pins, were inserted into the gunwales to act as a fulcrum for oars on small boats.This item was found along with two pulley sheeves (MAS-D100049) and a marble tile (MAS-D100050).TRANSPORT36391032/173MAS2017-03-14T00:00:00ZWATER CRAFT EQUIPMENTWith finder2017-03-14T07:28:01Z2017-09-26T13:11:50Z3211428415PAS57C96ECD001E82PAS57C96ECD001E822MAS MASMASWood11988CompletePOST MEDIEVALx41047NINETEENTH CENTURYx41047DivingSubmitted as wreck to the Receiver of WreckIMG_3921.JPG104images/MASABB2017-11-06T18:21:06.602Z
