Can unscrew everything and just leave the black base on the boat. Also made 2 7 " extensions that can be screwed in whichever hole needed. All threads are 1/2 " and extensions are 1" steel square tube. Base is mounted with 3/4 " Trailer hitch bolts that are carriage bolts. Cant catch anything on them or trip over any of it when holders are removed. Oh did i mention the jet black paint job i put on the setup!
