No doubt this is a well documented topic but opinions seem to vary.
For coastal cruising or even on inland waters, what type and weight of anchor would be suitable? The general answer seems to be 5kg with 2m of chain and a min of 30 m of non floating rope (8 mm) or a minimum of x3 depth of water.
So far I have not need one but the type of sailing I intend to carry out makes it part of the essential equipment to carry.
