Mine are a fixed style. Many are now available with a spring load that pulls the whip vertical when disconnected from.the boat. Those are easier with a tower. I take the front whip out of it's socket when I'm heading out and leave it laying on the dock. That's an easy work around.
The key to leaving a boat on whips is tieing it properly. You need a line from the forward and the aft cleat on the boat to the dock near the boat cleat. The boat should sit 2-3 feet out from the dock when those lines are on. Then you need a spring line from the fore cleat on the boat to the aft location on the dock and from the aft cleat on the boat to the fore locatn on the dock. (spring line is the name of the way of tieing the boat, the lines are normal boat roaps). There are lots of diagrams on the web if you search "spring lines".
If you can, leave the nose out so that waves break On the bow instead of the transom and swim deck. They are handy.
