The Sparta, with 32 crew on board, hit underwater ice on Dec. 16 that tore a 1-foot (30-centimeter) hole in its hull and caused it to list at 13 degrees. Several rescue ships had been hampered by heavy ice in the Ross Sea off the northern Antarctica coast before the icebreaker Araon finally pushed through and reached the Sparta on Monday, New Zealand Rescue Coordination Center spokeswoman Rosalie Neilson said.
The arrival was a relief to the crew, which had been desperately pumping out near-frozen sea water while awaiting rescue. At one point, more than half of those on board were forced onto life rafts.
A New Zealand air force cargo plane had previously made two parachute drops of pumps and hull patching gear that had helped keep the single-hulled Sparta from sinking.
