Another option might be the mast socket. Remove the screw on the underside and pull out the socket. It helps to put a line around the tab on the aft side of the post to give you some purchase since it’s a tight fit. Create a small loop of line around the post so that a section of the loop sticks out after reinstalling the post and you have a sturdy attachment point. When reinstalling the post, pay attention as there is a thin tab on the bottom cap that aligns with a groove in the post. I installed the one below as an attachment point for a stand up assist strap.
