Just got back from K-mart, was looking at their boating merchandise and realized something about my anchoring plan. I was going to use a fluke anchor but after seeing them in person I don't think I want to use them, the one required for my boat is HUGE, actually they didn't have one rated for my boat it was a step down and that was huge. I looked at the dimensions in the iboats store so I had a general idea of their size but it actually hit me in the store. So I was planning on purchasing a 15lb navy anchor instead, since I wanted to be able to put everything in a 5 gallon bucket the navy anchor would work out perfect. I know that I could read the manufacturer reccomendations and such but I figured I would ask. Does anybody use this type of anchor and if so how did it work for you? The river I am in is sandy with some rocks (mostly small) is there any reason why I shouldn't try using it?
