Thanks for including this video, since I am looking for a better anchor for some time now a Rocna seems to be a interesting one.

Let's print out the drawings from their website and see how (and if) such a thing would fit on my boat...

PS: @tobixen if you read this: We had a talk some time ago about the Rocna. I thought a Rocna is the one like the Rocna, but with a flat blade. Seems that you ment these ones, and I was talking about a slighly different one (is it calles bow anchor in english?).
