Sound Travels through Ice

The last 3 or 4 nights have been very cold which have made for interresting mornings. The peace of our sleep has been punctured by the sound of fellow live aboards pounding ice off their hulls, docks and lines. You can’t tell what direction the pounding is coming from either as it seems to come from all around. The sound travels very well through the ice and you could swear someone was pounding on your own hull with a hammer. It’s a new experience for me … I love the sound of pounding ice in the morning.
