A boat without a keel pointed at both ends is typically referred to as a "double-ended" boat. This design allows for efficient movement in either direction, making it versatile for various water conditions. However, the absence of a keel can make it less stable and harder to maneuver compared to keel-equipped vessels, especially in rough waters. Common examples include some types of canoes and traditional fishing boats.

KEEL
The keel boat was invented to provide stability and maneuverability to boats, especially in rough waters. The addition of a keel helps prevent capsizing and allows for better control over the boat's direction.
The keel is important because it forces the boat to move forwards when the force of the wind on the sails might also be pushing the boat sideways. The keel stops the boat simply going directly downwind.
The distance between the bottom and the keel of a boat is the draught (British English).
