Which method should be used to tighten the rope connected to the pickets?

Using a Spanish windlass is an effective method for tightening the rope connected to pickets in a rescue scenario. This technique involves creating a tensioning system by using a long object, such as a pole or a baton, which is inserted through a loop formed by the rope. By twisting the object, you create a windlass effect that applies significant tension to the rope, securely holding the pickets in place.

The design of the Spanish windlass allows for effective leverage, making it easier to tighten the rope without the need for complex knots or additional hardware. It is particularly useful in situations where controlled and precise tensioning is required. This method is efficient and can be quickly adjusted, which is crucial in emergency situations where time is critical and safety is paramount.
