Bone Voyage

Starting out
Talk to Curator Haig Halen at the Varrock Museum to begin the quest.

Make your way to the digsite and talk to Barge foreman in front of the barge (north of Digsite)

Travel north to the lumberyard and talk to the Sawmill operator.

He will give you a sawmill proposal and extra large cucumber. Now travel to the woodcutting guild in Zeah and hand the proposal to the woodcutting guild sawmill operator or guard at the front gate of the guild.

Return to the sawmill operator and then to the Barge foreman. He will let you board the barge. On the barge, talk to the Lead Navigator. He will believe the journey is cursed and ask you to talk to some experienced sailors in the pub in Port Sarim.

Talk to Longbow Ben in the pub in Port Sarim who will give you two options. Either a potion or a lucky bone. Return to the Lead navigator once again.

Visit the odd old man north of the digsite to receive the bone charm.

Speak to the apothecary in varrock with an unfinished marrentill potion and 2 vodka to get the potion.

Return to the barge and give the junior navigator the lucky charm, and the lead navigator the potion.

You will now have to steer the barge as the potion has made the entire crew sick. You will have to steer left or right using the controls on the interface.
