Why it is difficult to pull a boat on beach than in water?

Pulling a boat on the beach is more difficult than in water due to the friction between the boat's hull and the sand. In water, the buoyancy reduces the effective weight of the boat, making it easier to move. On land, the full weight of the boat rests on the surface, increasing resistance and making it harder to pull. Additionally, uneven terrain and obstacles on the beach can further complicate the task.
