It floats really well, can withstand salt water (the seed still lives after months of floating around) and even as the outer hard layer gives way, the bare seed can still float and survive on its own. Also young palm trees settle well on the nutrient-poor sand where they arrive.
The coconut itself is the seed of a palm tree. Coconut dispersal is by water. It can travel for thousands of kilometer then settles on the land to germinate.

Well, if you are talking about water disperal, it's the outer shell of coir that allows it to float. Barochory, the use of gravity also helps the dispersal. The weight of the coconut means that it hits the ground with enough energy to roll a considerable distance from the tree.
Coconut is dispered by water. It has waterproof outer layer or fibrus husks to help stay afloat in water.

Plants that use water dispersal for seed dispersal include water lilies, coconuts, and mangroves. These plants produce seeds or fruits that can float on water, allowing them to be carried to new locations for germination.

Coconut seeds are among some of the seeds that are dispersed by water. This is because these seeds are capable of floating on the water despite being very large. They have fibrous husks, which traps air helping it to stay afloat in water. Due to this type of dispersion, the seeds germinate at new sites away from the parent plant.

The four main dispersal methods are wind dispersal, water dispersal, animal dispersal, and self-dispersal. Wind dispersal involves seeds or spores being carried by the wind, water dispersal involves seeds or spores being carried by water currents, animal dispersal involves seeds or spores being carried by animals, and self-dispersal involves seeds or spores being dispersed by the plant itself.
