It doesn't work I tell you, those Rag and Stick guys are having us on.
I would stick to one ball if you are anchor, two balls signifies you are "Not Under Command"
As far as the other comments go as to wether you really need to use it, it is part of the IRPCS. If you were ever involved in a collision, then failure to comply with the Coll. Regs could cause some apportionment of blame to come your way.
Basically the law said you must use an anchor ball when your vessel is at anchor BUT some RIB owners will be glad to know that vessels under 7 m are allowed to not use one as long as they dont anchor near a fairway, anchorage or area commonly used by other boats.
