Keelguard required for drive on jet dock?
 

I am going to put my 20' sf in a marina drive on floating dock.Is a keel guard necessary? my boat is not pristine,so if is just an issue of cosmetics in the short term,I just assume let it go through the summer till fall. Any input appreciated,Thanks!

I'd put something on the dock rather than the boat - take it off later if need be
