Wild day!

This was the seen at Unapool today when we were traveling to Ullapool to do some shopping. It was a really wild day and bitterly cold wind and I can hear it just now. I think it may be gale force tonight by the sound of thing. Sunshinesilver posted a photo of a funny looking boat the other day here and I saw a similar thing today in Ullapool harbour. Does anyone know what it is used for? here
