A Frey Boat is a collapsible boat capable of turning into a Viking longship from a piece of cloth.
The Frey Boat is initially a piece of cloth like a handkerchief. When tossed into a surf, the cloth expands and folds into a full-size Viking warship with oversized oars, a figurehead carved as a wild boar and a green sail emblazoned with the Hotel Valhalla logo. The words: HOTEL VALHALLA COURTESY VEHICLE are lettered in white along the side of the prow.
- A Frey Boat is similar to the Skidbladnir, a ship that could sail anywhere in a short time and could be folded up for easy transport.
