Landing-stage
From Cantr II Wiki
The landing-stage is a freestanding building that must be built within a town's main area. Its prime purpose is to allow ships to dock that usually can't. Any ship/boat can dock to a landing-stage, even if they can't dock to the town's beach. The building can be locked, but boats may still dock.
The landing-stage can only be built when an area has access to a lake. If the area has access to the sea, a coaster harbour is required.
