1. Gravitational force: The gravitational force pulls the boat downward toward the Earth. This force is equal to the mass of the boat multiplied by the acceleration due to gravity (g = 9.8 m/s²).

2. Buoyant force: The buoyant force is an upward force exerted by the water on the boat. This force is equal to the weight of the water displaced by the boat. The buoyant force is what keeps the boat afloat.

3. Drag force: The drag force is a resistive force that opposes the motion of the boat through the water. This force is caused by the friction between the boat's hull and the water. The drag force increases with the speed of the boat.

4. Wind force: The wind force is a force that is exerted by the wind on the boat. This force can be either positive (pushing the boat forward) or negative (pushing the boat backward). The wind force depends on the speed and direction of the wind.

5. Mooring force: The mooring force is a force that is exerted by the anchor or other mooring device on the boat. This force prevents the boat from drifting away.

When these forces are in equilibrium, the boat remains stationary.
