I think you may be confusing rode for a boat anchor with chain for cement blocks. But even if that's not the case, 45' of chain is likely to make placement that is both legal and enjoyable impossible--the raft will swing in a radius of something like 40'.

I'd recommend bungee cords--purpose designed models are available on Amazon.
