We installed an Island Davit Set, Kato Marine. Had on for 2 seasons now. We opted for the heavier grade blocks and glad for it as we often haul the dinghy up with the outboard attached. I have the anchor points checked each season and all looks well. But it is not meant to be removable. I also had to custom fit my winter canvas to allow for them. Mounted large rigid solar panel on top of the davits too.
