Thanks for the skiff is a written note found in Death of the Outsider.
Transcript[]
Here's your skiff back, safe and sound at the waterlock, just like I promised. Ruiz got his fancy fish eggs to the lords, so we made good coin on this run. You'll get your cut next time we meet up. And don't worry, I had the oil levels checked and the throttle fixed by "Lieutenant" Dunbar, so everything is exactly where it should be.
Thanks again,

This note can be found on the Dreadful Wale's skiff in the canal in the Upper Cyria District, during the mission Follow the Ink.
