Port Guns in Marauder's Sea are coastal batteries that shell enemy ships. Range, levels, and Repairman.
Harbor law is simple: if it is not your hull, it is in range. Port Guns are the argument written in iron.
Coastal battery vs ships. Upgrade to level 10. Range grows from 80 toward 113 tiles (past the navy's 85-tile grab). Repairman starts healing at level 4. Volley size steps up with level. About 8 seconds to build. Cost scales, cap $400,000.
