An elegant ice yacht designed for civilian use during the historical period, featuring a polished wooden frame adorned with intricate carvings and decorative elements. The iceboat's sail, crafted from a blend of silk and linen, is dyed in a striking blue hue that stands out against the white expanse of the snowy terrain. The motorized mechanism hums softly as it powers the vessel across the frozen lake, its runners gliding effortlessly over the icy surface, leaving a shimmering trail in its path.
