Sailsleighs (Ice Ships) are the vehicles in which the Dwarves cruise the frozen lakes, rivers and sea shores of the Shiverpeak Mountains. Since the waters in that region are perennially frozen, sleighs are a convenient method of transportation. When there is no sufficient wind to sail, Dolyaks are used to drag the sleighs. Sailsleighs come in various sizes. Sleighs used to navigate the frozen bay of the Sea of Sorrows, marking the southern edge of the Shiverpeaks, can be huge in size. Some impressive sleighs can be seen in Droknar's Forge, Port Sledge and off the south-west coast of Ice Floe.
