While checking out the plans, I came across an item that I had previously missed. As shown on the plan, it shows an item called the Bulwark Sheave. I thought maybe I had missed it, but checking all the plans and the instruction book, I find no mention of a bulwark sheave. I am assuming that it is a sheave that is mounted into the bulwark. I think it would require some prep before planking the bulwark. Any thoughts? Pretty sure I will pass on this item.
