Using studland eco moorings

The new 5 ton ones have pickup strops and they have a few yellow floats on them along with a ring on top. The strop is around 10 foot long, a decent loop and a 'rubber' tube protecting the rope as it goes over the fairlead. The nearest ones are still around 300 metres from the shore.

Thank you, that prompts another question with my 8 ton boat - are there 2 sizes and how are they differentiated?
