UPDATE: A boat stranded in Oak Park pool has been removed.
A Sutherland Shire Council spokeswoman said the boat had washed into the pool after breaking from its mooring at Bundeena.
''The boat was secured by a salvage contractor on Tuesday,'' she said.
''The boat was successfully towed out by another vessel this morning at high tide.
''Several of the stainless steel poles and chain surrounding the pool have been broken and will be repaired as soon as possible."
