Which method is NOT recommended when you run aground?

When a vessel runs aground, the primary goal is to safely refloat it without causing damage to the hull or getting further stuck. Starting the engine and accelerating in this situation can exacerbate the grounding problem. This can lead to an increase in prop wash, which might drive the vessel deeper into the grounding or risk damaging the propeller and gearbox.

Using the other methods mentioned are generally considered safer alternatives. Pushing off with a paddle can provide necessary leverage to move the vessel, while shifting weight helps to balance the load and could potentially free the vessel from the shoal. Setting a kedge anchor allows for control in maneuvering the ship, aiding in pulling it free more gradually and safely. Thus, employing these strategies is generally more advisable than attempting to accelerate, which could worsen the situation.
