I created custom SS brackets for the upper attachment point. The key design criteria was that the davits could still rotate for full use of the swim platform and they were low enough on the transom to not interfere with the standard canvas when in use and buttoned down. This resulted in the the upward angle.
Also, in effort to not impact the usable area of the platform (mine is slightly narrow compared to factory original) I mounted everything on transom above he hull to deck joint.
Well done. It looks great. Thanks for sharing.
