Rigging

Mast

Main mast is 50ft above the deck. 14 inch diameter and 1/8" wall. --more or less.

Local manufacturer of steel poles: www.valmont.com

Steel Cable

"The design to go for, in a sheave carrying wire cable, is 40X the cable diameter. This is what we used to use for all shipboard sheaves where the cable had to have a long working life. Anything less than this figure and you reduce the working life of the cable. Going *much* less reduces the life really fast. So, 6mm should ideally have 240mm sheaves." --PDW
