There'll be a limited timetable for ferries from the Central Coast to Palm Beach for the next two days, and services will be diverted to Patonga.
It comes after a master boat ran aground at 5:45 this morning, with the last ferry leaving Patonga at 8am.
"The channel at Box Head is extremely shallow and deemed unsafe for crossing, to avoid further groundings Fantasea Cruising (Palm Beach Ferries) will be diverting services to Patonga for the next two days," the carrier says in a statement.
The next service from Palm Beach is due at 3:30pm.
Fantasea Ferries says the boat ran aground after powerful surf dislodged significant amounts of sand over the past few days.
However Peninsula Chamber of Commerce President Matthew Wales says the boat currently that dredged the Ettalong channel never even got to area where today's ferry ran aground.
"The money ($150,000 provided by the state government) ran out, the dredge never got that far, and of course, that's where the incident occurred. It was quite an unsettling experience for the skipper this morning as I understand it."
Fantasea has used text messages and mobilised Wagstaffe and Ettalong businesses to get the word out to commuters.
They expect the timetable to be back to normal by Saturday.
