I might have found our solution for a dink. The F-RIB which is a foldable dinghy that could sit up top. We wanted what is called the 330 but no one has them in stock. We did find the 375 which is about 12ft Foldable RIB’s | Product Categories | F-RIB. But remember it is foldable when not in use. You can go up to a 30HP engine, which I'm not. I'll go with a 9.9 HP- 15HP. Here is a video showing one. This is an answer for us due to space and not having to spend the cost of davits.
