A transport system includes a dry dock mounted on an air cushion platform to portage a ship overland. The system raises the ship from one body of water, hauls it across different surfaces, and launches it in another body of water. Ships and other water borne vessels can be portaged on air cushions across land, marsh, bog, or other impediments to navigable waters, or barge-like work platforms can be taken to work sites on water, swamps or tundra and retrieved after completion of the task. Transport system and ships can bypass canals and locks if these become inoperable, or the canals and locks can be circumvented if political conflicts deny their access.
