Clue: Old queen makes love among ship's timbers (8)
Answer: CAROLINE
Explanation: Definition: Old queen
O in CARLINE – Chambers defines this as "a strong beam used for supporting the deck in a ship, etc", so it's a timber rather than timbers. The echo of 1d is also perhaps a bit of a blemish. There have been various Queen Carolines, incuding the wives of George II and George IV: I don't know if any of them (or other Carolines) have particular pirate-y connections.
