Who controls ships flying flags of convenience in war?

A flag state has a say, but changing registration, ownership, and orders from a warship can all affect a merchant ship's wartime movements.

Question

Can a flag-of-convenience state decide where its registered merchant ships sail during war?

Short answer

Yes, but the flag can change, ownership matters, and a warship can impose an immediate direction to sail elsewhere.

Notes

A flag-of-convenience state has some say over where a ship on its register sails. The flag can change, however, and the ship's owner remains another relevant party. Naval coercion can also determine the ship's movements: a warship can order a merchant vessel to sail elsewhere. Registration, ownership, and the force available at sea therefore need to be considered separately.
