These animated knots are primarily for boaters, but many are useful for anyone who uses rope and values safety.
Rope used in boating is durable and expensive and is often handling heavy loads, e.g., when berthing, mooring, towing another vessel, preparing for a storm, or managing sails. The emphasis, therefore, is on safety, reliability, and convenience. In contrast to the fishing knots, value is also placed on being able to use the rope repeatedly and untie each knot without difficulty.
