Heaving to is a sailing maneuver used to slow down or stop a boat in rough weather. It involves adjusting the sails and rudder to create a balanced position, allowing the vessel to ride out waves and wind more safely. This technique is particularly useful when a sailor needs to rest, wait for better conditions, or address issues on board. During heaving to, the boat typically sails at an angle to the wind, which helps to minimize the impact of waves. This method can be employed on various types of vessels, including sailboats and yachts, making it a valuable skill for sailors navigating challenging waters.
