A huge ocean swell forecast to hit the Gisborne coast on Friday could force the arrested bulk carrier New Giant to leave its anchorage in Poverty Bay and put out to sea for safety reasons.
Marine forecasters are predicting a swell between 6 and 7.5 metres to develop offshore on Friday.
The New Giant remains under arrest after receivers for the ship's South Korean owners obtained a court order to detain the vessel on behalf of creditors.
Eastland Port marine manager Charlie Jamieson said yesterday their forecaster was predicting a swell in the Bay of more than 3.5 metres.
"It could be a swell to rival the one that happened during the Jody F Millennium drama," Mr Jamieson said.
