The party situated on the two ships and the crew evenly distributed, the pair of ships heads for the docks of the city Travilis, putting enough distance between them as to not be suspicious.
While you're sailing, Yolani or Colk (whichever of the two was put upon the pirate ship with Katherine and Remi) approaches the captains. "Ye'll be needin' ta sign in ta th' ledgers at th' docks. They like ta keep track a who's comin' an' goin', but they'll ask no questions other'n that. Th' captain a th' vessel'll need ta do th' signin'."
Several days later, the port city of Travilis comes into view on the horizon. Around noon, the two ships dock.

Katherine, Remi - The Pirate Ship
You pull into the docks easily enough, the crew getting the aging ship into port with few problems. The sound of a rope snapping as the ship drags to a halt seems to be the only problem.
A few men on another ship on your end of the docks watch passively as you dock, though they return to their work as soon as the crew pulls out the plank and lowers it to the dock.
A pedestal with a large book is quite visible at the end of the dock, a quill and inkpot next to it.

Hallandor, Ao'Thuir, Zumar - The Gazelle
You pull into the docks with no problems, the Gazelle easing into port with grace. As soon as the ship has stopped, an official walks down the dock and waits for the crew to set the plank down, allowing passage between the ship and dock.
"It'll be three crowns to dock your ship." The official, a well-groomed gnome in blue, calls. "And I'll need the name of the ship, and her captain." As he speaks, he takes a small book out of a pocket, accompanied by an inkpen.
