What is the gunnel on a boat?

The gunnel of a boat is the upper edge of the side of the boat, where it meets the deck. It is sometimes referred to as the "wale". The gunnel is an important part of the boat, as it provides support for the deck and helps to keep water from coming into the boat. It also provides a place for passengers and crew to hold on to when the boat is moving. The gunnel is typically made of wood or metal, and may be covered with a rubber or plastic coating to provide additional grip and protection.
