So far I've visited Ko Maprao, aka Coconut Island, twice already. For the pizza at the Village Resort, and even on a boat trip to walk around the island. This time, I'm visiting the Sea Food rafts between Coconut Island and Phuket Island.
The principle is simple, fish, seafood and shellfish are kept in pens under the rafts. You visit the rafts by boats from Laemhin pier, these boats are free, but the captains receive a commission for customers they deliver.
There are two main rafts, Kruvit Raft, and Black Crab raft. You can visit either, I chose Kruvit because it was nearer to the pier at Coconut Island. Since the boat man gets paid for my visit, he was happy to drop me off at Coconut Island first and wait for me to finish exploring the island.
