This last visit to the Cape found "replace mooring buoy" on my list. I purchased the buoy and line and snagged my nephew Alex to show him the ropes. One thing lead to another and we ended up rebuilding the whole upper end of the mooring, with Alex doing most of the splicing.
At the end, he even made a dog leash, using a dinghy clip that does not get fouled with sand,
What a delight to pass this on!
