Hi Ian,
Thanks for the feedback.
As we have recently been putting out the buoys (well Andrew has) in seemingly random locations with people from the pontoon shouting left a bit, right a bit; I can only assume that we haven’t been using the block and loops. That raises the question in my head as to how we would locate the blocks again if the buoy has become detached and the rope has pulled back through the loop.
