Navy divers have managed to locate the wreckage of one the trawlers, which sank off the south-east coast last week.
The 'Pere Charles' went down off Dunmore East with five hands on board.
The divers had been prevented from reaching the vessel because of dangerous sea conditions.
But lieutenant commander Terry Ward says bad weather has again stopped the underwater search - for the time being:
"They dived to about 10 metres beneath the surface," he said. "But unfortunately the swell made it impossible to go ahead with the dive. They'll stand by for the remainder of the day and hopefully if they get another chance they'll go out again."
