Thirty years ago a strange board mysteriously washed up on Bonaire. Some called it ocean debris. Others called it a gift from God. A few boys patched up the board and strung up some cloth. Then they stood on the board and hung on. Windsurfing was here. No one took to it quite like a 20-something fisherman, Elvis Martinus, who in 1992 qualified for the Olympics. He couldn’t go to Barcelona because he had to work, but he did lead a new movement with the wind.
