If ya want to get technical you can mount a pole holder (salt water type or PVC Pipe) and take the one off your back patio and use it just fine!! I did that in Florida with my CC after my T Top broke and I did not have the $$ to replace it! I just slipped the patio Umbrella in the pole holder opened it up while at anchor or even drifting and all good. On the ride in take it, store it and put back on the patio before the wife ever knew it was gone! Cheap I am, Genius I am not
