We hear only what shore-based receivers pick up, and that network is uneven — dense on some coasts, absent on others and in mid-ocean. A register with no vessels here simply means none of its ships have been heard by those receivers — it says nothing about the size of the Cocos (Keeling) Islands fleet.
Listed newest position first, capped at 150 rows. “No position held” means we have a static report from the vessel but no position report.
