For the dinghy -- I use a spinnaker halyard and have experimented with a number of techniques and bridle configs. I rigged a 3-point bridle with rope and can use that to hoist horizontally, but the best (for me) is to first remove the motor and just use the bow attachment to haul it up vertically. My boat has a vinyl rub rail so I slide the dinghy bottom over that as it's raised. I guide it while my wife operates the electric winch for the halyard. When it comes aboard I control and position it, as she lets it down slowly. This method can also be done single-handed in stages by going back and forth between the winch and repositioning the aft end of the dinghy in steps.
For the dinghy motor I use a Forespar Motor Mate, which I modified: I mounted a Forespar Marelon winch to the top so it's easier for her to use without hard pulling. However, she finds it awkward to simultaneously crank and tail the winch in that position so I'm going to try a crank-type Fulton trailer winch (spooled line, so no tailing required).
We carry the dinghy on our side nets. This image shows it upright but I only keep it like that when harbor hopping in fair weather. If I expect to leave it when we're away from the boat, or expect rough seas or T-storms I invert it and secure from 3 points.
This image shows the Motor Mate on the stern rail, with the Marelon winch attached to the top.
