Editor’s note: Has this happened to you? You’re out for a sail and realize the cockpit-led reefing line or mainsheet that has sailed many years with you is showing signs of wear or UV damage. Back at the dock you remove it, buy a replacement line from a chandler, and then, ready to run the new line, realize you don’t remember whether to run the new line inside or outside the lazy jacks, or how to thread it through the multi-sheave blocks to gain the necessary purchase… contributor Gregg Bruff has the answer:

In a plastic notebook binder, I keep a sketch I made of how the mainsheet runs through the blocks correctly. In the same notebook I keep also a cheat-sheet on the Mayday procedure, a layout of my switch control panel (upside down, as I access it from the cockpit), and any notes I make while sailing.
