Heligoland is strongest on Isolation 9/10 — Roughly 70 km of North Sea separate the island from mainland population sources and normal access is by ferry/ship. A year-round ferry, working harbour and established resident/tourist population prevent the absolute highest separation class.. Its clearest scored constraint is Defensibility 2/10 — The canonical Base is an inhabited whole island, not one harbour or bunker. Individual buildings and cliff sectors are secureable, but twenty people cannot defend the complete coastline, harbour and settlement as a continuous hardened perimeter. Sea separation is credited principally in Isolation/Exposure rather than double-counted as fortification..
