Castaways stranded on an island in Micronesia were rescued after spelling out "HELP" in palm leaves.

The U.S. Coast Guard picked up the three sailors stranded on Pikelot Atoll after they got into trouble in their small 20-foot open skiff.

The men, all experienced in navigating local seas, reportedly embarked on a voyage from Polowat Atoll on Easter Sunday equipped with an outboard motor.

But six days later, the Joint Rescue Sub-Center Guam received a distress call from a relative of the three mariners reporting that her uncles were missing after they departed on a 100-nautical-mile voyage and had not returned.

Thanks to the coordination of the Coast Guard in Micronesia/Sector Guam and the U.S. Navy, the men were able to be located—with a "crucial factor" being their idea to spell out ‘help' on the beach.

The breakthrough came when the U.S. Navy P-8 Poseidon aircraft confirmed their presence on April 7 on Pikelot Atoll, and the crew successfully deployed survival packages to sustain the men until further assistance could arrive.

"In a remarkable testament to their will to be found, the mariners spelled out "HELP" on the beach using palm leaves, a crucial factor in their discovery. This act of ingenuity was pivotal in guiding rescue efforts directly to their location," said Lt. Chelsea Garcia, the search and rescue mission coordinator on the day they were located.

The U.S. Coast Guard added that they strongly recommend all mariners equip their vessels with an Emergency Position Indicating Radio Beacon (EPIRB) to enhance safety on the water.
