One of the many commendations you can complete while you sneak aboard other ships is the ‘Hidden in Plain Sight’ commendation.
To complete the commendation, you must sneak for a distance on an enemy player ship while Disguised.
To perform this sneaky commendation, you’ll first need to board the closest pirate ship. Once you on, you’ll want to find somewhere to hide so you won’t get caught!
Hidden in Plain Sight
To complete the ‘Hidden in Plain Sight’ commendation, you must sneak 10,000 meters on an enemy player ship while Disguised. Unlike Hide Emotes such as the Barrel Disguise Emote, you can move while Disguised as a Chest or Barrel.
Once on another pirate’s ship, find somewhere you can hide away and move around without being detected. Finding a Galleon would be ideal. The Galleon is such a large ship that you are less likely to run into the crew. You can make your way to the lowest level of the hull and walk around there in Disguise, hopefully without being interrupted. You could also try walking around the back balcony of a Galleon for a safe place to walk and increase your sneak distance.
It doesn’t matter if the ship is sailing the sea and traveling any distance. The distance you need to sneak for this commendation is you walking around on the enemy ship. Unlike the ‘Comfortable Sneaker’ commendation, you must be on another pirate’s vessel. You can’t work on this commendation on a Skeleton Ship.
