Madleen set sail from Sicily towards Gaza on Sunday. The ship is loaded with humanitarian aid for Gaza's population.
We are now sailing outside Egypt's coast, says the German human rights activist Yasemin Acar to AFP on Saturday.
The ship's crew has reported a number of observations of drones during the journey. According to activists on board, drone surveillance is intended to intimidate them.
We are fully aware of any potential consequences, says Acar.
She does not want to say when or where the ship will try to get in towards Gaza.
Freedom Flotilla was originally supposed to sail to Gaza with another ship in May, but that ship was attacked according to the organisation by drones on international waters outside Malta.
A high-ranking source within Israel's Ministry of Defence stated in the week for the newspaper [The Jerusalem Post](The Jerusalem Post) that the ship will neither be allowed to approach nor dock in Gaza.
