Searches for the bodies of the seven fishermen missing for a fortnight will resume in the morning.
Divers hope to be able to dive at two separate locations, but this will depend on the weather and diving conditions.
Divers from the navy plan to go down to where the Pere Charles is lying 4km from Dunmore East in 35m of water.
And divers from the Garda Water Unit hope to dive at a site 5km south east of Ram Head in west Waterford to see if the wreck of a boat located 30m below the surface is that of the Honeydew II.
The Coastguard Service has set up two seperate command centres, one at Dunmore East which will deal with the Pere Charles, and the other in Youghal, which will deal with the dive at what is hoped is the Honeydew II.
Divers did not manage to dive at the Pere Charles today because of weather and tidal conditions, and tomorrow's dive off Ram Head will be the first attempted dive at that location.
