Seamanship 5 Practice Test

What is a heave-to and when is it appropriate to use one?

A heave-to is a high-speed maneuver to escape danger.

A heave-to is a method to anchor in shallow water.

A heave-to is the process of lowering lifeboats.

A heave-to is a controlled, stable position in heavy weather or for maintenance; used to ride out rough seas, conduct tasks, or give relief crew breaks; achieved by wind and rudder settings that hold the vessel nearly stationary.

The idea being tested is how a heave-to creates a stable, nearly stationary position to handle a vessel in heavy weather. You achieve this by trimming the sails and setting the helm so wind pressure on the sails and water acting on the rudder counter each other, holding the boat in a steady heading with little forward motion. On many fore-and-aft rigs, that often means backing the jib against the wind and using the rudder to keep the bow into the wind and waves, so the boat stays roughly in one spot or moves very slowly.

This setup is useful because it lets you ride out rough seas more comfortably, perform maintenance or repairs, or give relief crew a break without the vessel charging ahead or taking hard pounding. It’s not about speed or escaping danger, and it isn’t about anchoring to the bottom or lowering lifeboats—that would be separate actions.
