Hi simple sailor.
You have to show that you have taken steps to protect your members, the public, and any workers.
We drew a diagram of our parking area along side the lake,when we park our cars side by side, just enough to open the car doors without touching , that would indicate two metres. We sail our boats from in front of our car, still-two metre away from each other ,we will wear gloves when needed to open, or shut our entrance post (gate).if needed we can sail along the side of our lake, still maintaining two metres. Keep an eye out for the general public , and inform them of the two metre distance guidelines.
Or make up a notice board reminding them of the two metre.
That the general idea, we actually drew a diagram with all this on ,and sent a copy to all our members, and a copy to our council. They were very happy with it and gave us permission to start to sail again...hope you can understand it, and . hope all that helps mate...
