Actually, the correct word would be "digipeater", rather than repeater - basically a device that hears & records AIS signals, then sends them out again on one of the two AIS channels. If you located one (or more) in high places (mountaintop or high tower), it would facilitate long-distance AIS coverage.
See:
PMAPI AtonisPro-R AIS Repeater

https://navcen.uscg.gov/?pageName=AISworks Note that the 5th paragraph refers to AIS repeaters.
That said, I think it's more likely that propagation is causing the OPs event.
