My local lake has a low water level, which mean that the shore is rockier than it should be at the boat ramp. It also means that my dagger board will get eaten by the rocks if I don't pull it up in time(which usually happens). I'd like to protect it, after I repair it, to keep this from happening. What would be the detrimental effect if I wrap the bottom portion of the dagger board in some type of protective material, like a split rubber hose? Would it effect how the boat sails? I don't race so I don't care too much about speed.
