A keel is the long fin that comes out of the bottom of the boat. You could make it using any missle shaped object for the botton and a long narrow pice conecting it to the boat itself
The keel provides stability AND steerage.

KEEL
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).

The keel of the boat is made of lead and weighs 600 lbs. Even though customers can make me feel upset sometimes, I try to keep an even keel when dealing with them. That boat will not be able to sail in such shallow water because of its large keel. Sailboats with a mast of any appreciable size need a keel to remain stable. I am so tired, I feel like I could keel over at any moment.
Ben Lexen invented the winged keel for the American Cup
Viking longships, starting in the 700s AD, had a mast with a sail. To make a boat with a sail stable, a keel is needed to counteract the tipping forces the wind places on the sail. Prior to the sail being added, longships did not require or have keels.
