As was raised on another thread, suggestions are needed for the large fire and rescue boats, fire away below...
I have a few personally:
Fire on a Tourist Boat: - Requires Tourist Boat Dock as POI
Both 1 of a Large Rescue and Fire Boat required, Ambos and 1 swift water rescue boat. 1 HAZMAT, 2 Fire Trucks, 1 batallion Chief.
Up to Five casualties, 30% chance of transport, general surgery.
Fire on a Cruise-liner: - Would Require a cruise-liner Dock as POI
Both 1 of a Large Rescue and Fire Boat required (potentially more Fire boats), Ambos and maybe a swift water rescue boat, MCV, 2 batallion Chiefs, 5 Fire Trucks, 2 Heavy Rescue, 2 Mobile Air, 1 Water Tanker, 1 HAZMAT.
Up to 20 casualties, 30% chance of transport, general surgery.
Rescue Boat, 2 Swift water rescue boats, (Police Heli), 1 Ambo,
One casualty, 70% chance of transport, general internal.
