This umbrella is made to fold up with the wind preventing it from breaking. Also the bracket does screw down on the umbrella holding it in place, and adjusts to move umbrella where needed. If it doesn't work it goes back to the store.
But yes, I've spent money trying to do things cheaper but when all was said and done I should have just bought the Hobie product!! For example, the Hobie rod holders: I was going to make my own using PVC. When completed I still went out and bought the Hobie rod holders! But you still can't beat using 2" PVC for bunks compared to the PA cradles!!!!!!!
