ask the expert
John;You need to give me a call on this one as I know your boat too well. For your information, the top of the compression post is secured on top of the deck and will not move. The bottom rests on a plate underneath the table in a small compartment. The plate that the compressin post rests on is tthe bracket which holds the centerboard in place. Should you secure the base of the compression post to the plate, you will break a seal allowing water to come in when the boat is under way. Therefore, the base of the compression post will sit on the plate but it is not screwed in. I would question the amount of pressure that the table is being exerted to cause the post to sway.As for another matter, I have your bimini which was repaired at no cost and I will ask that you contact me to make the exchange of the loaner that I gave you. Also, congratulations on getting married and many years of blissful relationship.Crazy Dave Condon
