Ice Traverser

Ice is not difficult terrain for iceboats. However, they're unable to travel over land unless it's completely covered in ice.

Steel Keel

Iceboats have steel blades affixed to their keels and outriggers that enable them to travel over ice at tremendous speed.

Description In addition to sailing across open water, this vessel can also travel at high speeds over frozen rivers, lakes, oceans, and fjords.
