Don't anchor much but when I do my boat has about 48ft. of chain and a good size Fortress anchor. When I do anchor it's usually in less than 15 ft of water so up to this point I havent't seen the need to add any rope to this configuration. Now I'm having second thoughts and am going to add some 5/8 line. Here's the question, should I reduce the amount of chain or just add the line to the existing chain as it is? Also, when I do anchor in 8-12 ft. of water should I just go with the chain or let out more scope to have some rope in the equation?
