Almost all materials I need to build some floating buoys have now been delivered. For example high visibility fabric, ropes, silicon tubing (the kind of tubes often used in hospitals for all types of fluids) and empty water bottles. So, towards the end of this week I will be able to actually build the floats. They will represent some of the yellow dots in the map about Shifting Spurn.
In order to find out the right size for these swimming devices I marked them into an image. - This is the way to do it when you haven't got a car to quickly drive to Spurn.
