Tips for Visiting Marinas in Wilmington
- ✓ Call ahead to confirm slip availability — especially on peak summer weekends and during fishing tournaments. See all Illinois marinas.
- ✓ Verify fuel hours before you commit to a destination — many small-marina fuel docks close earlier than the marina office.
- ✓ Ask about pump-out availability and any environmental restrictions on holding-tank discharge.
- ✓ Confirm transient slip rates, electric/water hookup, and any minimum-night stays before booking.
- ✓ Monitor VHF channel 16 (or the marina's posted channel) on approach to coordinate dock assignment.
