Just Keep Swimming and Viking Funeral are two achievements tied to the same quest. In City of Light down south, Calabar wants you to get a fishing map. Save before accepting the quest so you can reload later. Accept the quest and once you leave the building, Lenny wants you to burn the boat instead. Just Keep Swimming is ignoring Lenny and getting the fishing map. Viking Funeral is accepting Lenny's quest and burning the boat. Pick one, complete it, reload your save and choose the other option for both achievements.

There are 2 secret achievements:

In City of Light, head to the center of town with the band playing. Talk to Garos and donate gold to the band to unlock the achievement.
