Vier Gebroeders, on the slipway this week, highlights this family orientation, as it means Four Brothers. I myself was born on a barge called Twee (two) Gebroeders.
I suggest taking a good look at the Vier Gebroeders, then compare to Pete Townshend's Dutch barge. A striking resemblance, I'd say. Indeed they are the same type: tjalk.
African beads anyone?
There's more where this came from: Grahamstown, South Africa.
