I am casting a new concrete lump for my swinging mooring, using an old Truck tyre as a mould. It will hold approximately 0.3 cubic metre of concrete. According to my research that should give a weight of about 800 Kg. My mooring contractor says he dislikes concrete as it is "lighter in water" than steel/iron. Of course it is lighter. Surely the key element is the weight of the lump (concave base assumed)? It is for a 23ft Ketch with a displacement of 2400 LBS.
Is my estimate of weight about right? Will that be heavy enough using 3metre of 1inch ground chain in 5 metres max depth? Comments greatly appreciated.
