Two men who recently spent five days on a coral island wished they had stayed there longer. They were taking a badly damaged boat from the Virgin Islands to Miami to have it repaired. During the journey, their boat began to sink. They quickly loaded a small rubber dinghy with food, matches, and cans of beer and rowed for a few miles across the Caribbean until they arrived at a tiny coral island. There were hardly any trees on the island and there was no water, but this did not prove to be a problem. The men collected rainwater in the rubber dinghy. As they had brought a spear gun with them, they had plenty to eat. They caught lobster and fish every day，and, as one of them put it 'ate like kings'. When a passing tanker rescued them five days later, both men were genuinely sorry that they had to leave.
