Disaster Rescue ships

The recent earthquake disaster in Haiti deserves help and all should contribute what they can.

More generally, the world needs more disaster rescue ships. They should be of several types: hospital ships of multiple drafts for different harbors, emergency electrical power ships, communications ships in addition to whatever emergency communications might be standard on the other varieties of ships, emergency sanitation and shelter ships capable of deploying temporary sewerage and water systems and civil reconstruction vehicles such as bulldozers and cranes.

Rescue aircraft are also desirable, but they can do less because of the limited cargo capacity on devastated airfields. Most of the world's population is near the sea. Disaster aid by rail is also possible and it could be done by keeping modules ready for loading on flat-cars.
