Voyage help

Since the servers are temporarily down I'd like to see if anyone else is having an issue with one of the voyages. Can't remember what the voyage was called, but it was centered at Crooked Masts. The second to last part wanted me to go to the "Northwest grave of the Kraken's prey" and to play a shanty. I tried the ship wreck on the north part of the island where the skeleton is impaled on the ship and played both instruments, but nothing more was revealed on the riddle. Anyone have any luck with this one?
