Heel – Definition and Pronunciation
What is Heel?
Heel is a term referring to the angle of a sailboat when it leans to one side while sailing.
Examples of Heel
Gear nets or gear hammocks are handy for storing clothes along the V-berth. They keep your clothes easily accessible yet out of the way, and they stay put when you’re on a good heel.
From “Cruising in Comfort on a Sailboat”.
On older boats it may go through the deck with the heel connecting with a mast step just above the keel.

You will find that exceptions can be made on those pipes or systems in which the outlet is above the waterline, but if a boat is operating in rough seas or it is a sailboat that will heel over, those above-water outlets can find themselves submerged (the only pipe that doesn’t have a seacock fitted is the engine exhaust pipe).
From “Marine Plumbing – Systems and Materials”.
