Watch tackle:

A watch tackle or Handy Billy is most useful contrivance, and should have a place on every cruising boat. It is made of a single and double block, both having hooks, or else the single having a hook and the double an eye. For a small yacht, blocks carrying a 15-thread rope are heavy enough. When stretched to its best there should be at least 15 feet drift between the blocks. This tackle saves oceans of labor, and makes the heaviest job light. If your anchor sticks, Handy Billy will bring him to terms. If you get aground, he will give a strong pull on the warp to get you off. If the bobstay breaks, or a shroud parts, he will help to keep the mast in while repairs are being made. You want good, strong blocks, as there is a tremendous strain when all the beef is on this tackle. Keep Handy Billy in a safe and easily accessible place, and he will pay you well for his lodgings.
