The Endymion was a small sailboat approximately 16 meters in length which was owned by an Australian by the name of Anthony Corbyn. In October 1998 the vessel ran aground near Makawa Island and was considered a total loss.
The sailboat sank with all its rigging and equipment, settling at the bottom of the reef in approximately 17 meters of water. Over the years submerged underwater the wooden main deck of the vessel has disappeared and the rest of the wreck has been colonised by soft corals.
No other information concerning this vessel has been found to date.
