Over SealandSealand along with a Motorboat seen parked by its rope ladder

Sealand is an easter egg which is merely a platform off the coast of Wolin. and there is speculation that Sealand is a marine base or government base due to the words 'SEALANDGOV' on a side of the platform. There are no lights on the platform.

Sealand in comparison to the Trafalgar

Ships can approach the other side to refuel. This is a very handy feature since ships like the Motorboat, which may be used to access Sealand, has a very low tank capacity. Therefore, the player can refuel their vehicle in order to ensure their return back to Wolin or any other port.

The interior of the first room on Sealand

On the platform are three rooms, each connected with a corridor. The first room is a break room/kitchen. The left and right walls are lined with counters, while the left wall is lined with cabinets on top. There is a stove and a sink on the right, as well as a wooden table with seating for 4 people. There is a window from the room which overlooks the sea.
