I rarely used my dingy. However when I did, this may be an alternative for you, I lashed it to the swim platform. It was not as easy as having davits but it worked quite well. I used two ratchet straps secured at the cleats and crisscrossed them to the center of the stern rail. I replaced the open hook at the long strap end with a brass spring clip. I would clip the strap to the swim step cleat. I would bring the dingy to the swim step as you would with davits, with the bow of the dingy to port. From the swim step I would insert the unsecured end of the port strap through the painter ring and then lay it on top of the dingy. I would then take the starboard strap and make one wrap around the tube that is against the swim step and then under and over the outer tube. Then grab both straps and lift the dingy as you would with davits. temporarily tie to rails to hold it in place. Then one at a time attach ratchet ends to the strap, hook onto stern rail crisscrossed and tighten away. I would then also tie the painter line to the stern rail as a secondary tie, just incase. The tube should lay on the swim step. I went many miles this way and in rough seas on occasion and never had a problem in ten years. This sounds a bit more complicated than it is. I would say it takes about ten minutes to set up. And by the way I used a Torqeedo with the shaft mounted to the stern rail on a bracket I made out of 6" X 5/4" thick treated lumber with the shaft on the swim step side so there was no room taken up in the cockpit.
If you plan on getting davits next season then I would definitely not bottom paint the dingy.
