The term 'Keel Part' refers to two components of a boat's hull, the SKAG and the skeg. The SKAG is a triangular piece of metal or wood that is attached to the bottom of the boat's keel and extends outwards from the stern. The skeg is a fin-like structure that is attached to the bottom of the boat's keel and extends outwards from the bow. Both the SKAG and the skeg provide stability and protection for the boat while it is in the water.
