The Commissioners of Irish Lights say it would not be feasible to mark a treacherous group of rocks off the Connemara coast which almost claimed the lives of 10 fishermen at the weekend.
The accident occurred at the same location two years after the loss of 12 lives from the Spanish flagship, Arosa.
The French-registered Spanish vessel, Lioran, was leaving Rossaveal, Co Galway, in favourable weather conditions when it ran up on the Skerd rocks some nine miles west of the Carna coast.
As in the case of the Arosa in October 2000, radio contact was lost for a time with the Lioran.
However, the Irish Coast Guard scrambled a rescue helicopter and lifeboat assistance, and the vessel was successfully hauled off the rocks and towed back into Rossaveal.
All 10 crew were reported to be shocked, but safe and well. The 38-metre vessel sustained a hole on its starboard side.
Two years ago only one member of the crew of the Arosa survived when the trawler hit the Skerd rocks while trying to make shelter from bad weather.
Among the 12 who died were three African crew members whose bodies were never found.
Gardaí have been unable to contact their next-of-kin in Sao Tome, an island republic off the west Africa coast.
A spokesman for the Commissioners of Irish Lights said the sea conditions were such that the area would not sustain a light.
Such is the strength of the wind on the rocks that a wind measurement mast was recently erected by a Connemara company to test suitability for wind energy.
