OK we worked with the crew to steal the ship and lure Benny out - then we killed him and when we went back to the window we arrived through there was no option to leave (did not use a hook) - so we fought our way to the usual entrance/exit - (killed everyone in the outside areas)  and it is closed and I can't find any way to do anything with the gate or the crane to open the port gate and leave???

My bad! I was trying to use the crane and not the windlass - problem solved we are off to plunder elsewhere! 😆
