From A Wiki of Ice and Fire
Shipbreaker Bay is a large bay in the Stormlands along the eastern coast of Westeros. Rocky and frequented by storms, it is named after the large number of ships that have been destroyed in its waters.
Storm's End sits along the northern shore of Shipbreaker Bay, while Griffin's Roost is on the western shore. South of the bay is Cape Wrath with the rainwood and Rain House. Tarth sits in the narrow sea east of Shipbreaker Bay, with Evenfall Hall situated along the bay on the western side of the isle. North of Shipbreaker Bay are the Straits of Tarth.
Lord Steffon Baratheon and his wife, Cassana Estermont, died when the Windproud broke up within sight of Storm's End during a sudden storm.
During the Siege of Storm's End, the smuggler Davos navigated the rocks of Shipbreaker Bay to bring supplies to the besieged Stannis Baratheon.
